According to China’s Sina site, owning an air force ready to fight requires the state to pay huge costs, something not every country can do. “Any country that intends to build its own air force must have a solid economic foundation, otherwise they will not be able to maintain a fleet of fighter aircraft,” Sina said. clear. Chinese military experts noted that the Flanker-class fighters were the main foundation of the country’s air force, and they tried to enumerate the factors that influence the cost of the flight. The first indicator to take into account is the fuel consumption, which is influenced by the fuselage weight and the weapon’s weight. Besides, there is also the flight mode (at a lower fuel consumption rate as opposed to tactical maneuvering); engine model (consumption increase is proportional to engine power); pilot skills. The Su-27 Flanker is used as an example. The total weight of fuel carried by the aircraft is 9.7 tons. At the same time an aviation fuel specific gravity of 0.85 will result in a fuel volume of 11,200 liters. “In a normal flight, the Su-27 in cruise mode, excluding maneuvers, fuel consumption per hour is 3,750 liters, its flight time is 3 hours”. If you calculate that with the current jet fuel price of 6,500 yuan per ton ($ 990), the Su-27’s one-hour flight time will cost 63,000 yuan ($ 9,590), “Sina said. just the most economic state “. If we take into account take-off time and the pilot’s tactical actions, fuel consumption increases by at least three times, or about 200,000 yuan per hour ($ 30,400), Sina said. Given this fact, the Chinese newspaper argues that average countries simply cannot have a large-scale Air Force, if one takes into account these factors. In addition to the amount of fuel consumption, the purchase of ready-made fighters abroad requires the payment of tens of millions of dollars per aircraft, possibly hundreds of millions of dollars. After solving the problem of purchasing combat vehicles (including accompanying weapons), it is necessary to continue investing in the maintenance, maintenance, construction of ground infrastructure and pilot training. “The money to maintain a large number of fighters is extremely expensive. But without its own air force, any country in the modern world could be plundered by the opponent”, Sina confirmed. However, the Chinese newspaper also noted that the flight on the Su-27 is not the culmination of costs, as an hour of flight of the F-35 stealth fighter is estimated at $ 36,000, even though it is only a single engine. The aforementioned amount is mainly calculated into the depreciation cost of machinery or the wear and tear of stealth coating, guaranteed weapons, showing that owning the fifth generation fighter is still a dream of many countries.

Thuy Van welcomes her first son in November 2020. After more than a month of giving birth, the runner-up returned to the Vietnamese fashion village. In Vietnam International Fashion Week At the end of December last year, Thuy Van strode on the catwalk with Khanh Van and Kim Duyen in designer Nguyen Cong Tri’s show. Contribute to stay Vietnam International Fashion Festival 2020 Thuy Van takes on the opening position for designer Kieu Viet Lien’s show. Chat with Zing About the secret of postpartum postpartum postpartum, Thuy Van said: “I don’t take long maternity leave. In addition to eating and exercising properly, I quickly get back to work. Going to work also helps my body to move a lot. more, thereby dissipating excess fat “. “Health will go hand in hand with beauty” I always think women have to be beautiful. Pregnant and becoming a mother, I have to be even prettier. First, beauty is for yourself. When we are beautiful, we will have positive emotions and motivation to work harder in life. Runner Thuy Van maintains a radiant beauty before and after having a baby. Many opinions say that mothers are always cheerful and radiant, their baby will be beautiful. I look forward to this for my child. If we know how to maintain our beauty, we will be happy and healthy. Mother is fine, you will be fine too. During pregnancy, I usually wear loose fitting clothes for easy portability. Besides, I also like clothes with bright colors. The moment I had a baby coincided with a complicated epidemic progression. Everyone, including me, is very worried and insecure. Fashionable dresses are something to help me reassure myself, feel my life brighter. After giving birth, I still appreciate the factor of comfort in dress for easy care and breastfeeding. Regarding the fashion style of the workplace, I choose the outfits that show professionalism and elegance. They help us to emphasize our own personality and color. Don’t forget to take care of your skin In the past, I used a variety of cosmetics. However, when I have a baby, I realize that all the products I use will affect the baby. Therefore, the selection of cosmetics becomes more thorough. I no longer use most cosmetics I used to use before pregnancy. Instead, I turn to cosmetics that contain ingredients that are benign, safe for mom and baby. I always prefer skin care over makeup. I love some skincare products like toners, serums or lotions. They keep my skin hydrated and moisturized enough. Thuy Van takes good care of her skin to maintain a smooth, vibrant appearance. Every pregnancy and childbirth is a strenuous process for mothers. Therefore, pregnant women are prone to many skin problems. I also researched pre-baby stretching, acne or edema to find out prevention measures. Before showering, I massage my skin with coconut oil. It helps skin to be moisturized, supple, and maintained for better elasticity. Thanks to the application of the good routine, my skin is fortunate enough to not have many problems. When not pregnant, women should learn the secret to beautiful skin. Son is the first cosmetic item in my bag every time I go out. Son helps less pale face. Next, I have sunscreen. The weather in Ho Chi Minh City is very hot, UV rays are active, so this is an indispensable skin protection cosmetic. Besides, I bring an antiseptic hand sanitizer to protect the health of myself and my baby. I use hand sanitizer to wash my hands before touching my baby to make sure it’s safe. Maintain proper eating and exercise Speaking of the secret to postpartum postpartum postpartum, I think the most important thing is breastfeeding. When breastfeeding, the body naturally loses weight. In addition, living habits, diet and exercise also significantly affect. If we don’t lose sleep or worry too much, our bodies will produce a lot of energy to work. Since then, the consumption of excess fat also takes place smoothly and quickly. Thuy Van believes that hard work contributes to rapid weight loss of the body. I don’t have the concept of “eating for two”. I eat in moderation to provide adequate nutrition, good for myself and my baby’s health. I like a variety of plant foods like tofu, nuts, grains and soups. They help me get more milk. At the beginning, I limited my seafood consumption but then gradually started eating normally again. Also, I tolerate a lot of fish and white meat like chicken. As for red meat, I only eat once a week. Regarding the form of movement, I choose to practice yoga. I have maintained a very regular practice from pregnancy to now. If I have free time, I usually go for walks and jogging around where I live. Going back to work after a short time of birth helps me feel good. Being physically active also assists in releasing excess fat and losing weight. Appreciate the opportunity to be close to the audience At the end of last December, I received a fashion invitation from designers Cong Tri and Kieu Viet Lien. I feel very grateful for being remembered by the brothers and sisters as well as giving me a special place in the show. Therefore, there is no reason for me to decline these invitations. On the other hand, by that time my health was stable. I was able to finish well on the show so I decided to accept. I don’t think I’ll leave the spotlight after getting married. Besides a favorable career, I also received a lot of love from the audience. That’s too lucky for me. If there is any opportunity close to the audience, I appreciate it. Thuy Van became active again after having a baby. This year, I participate Miss Fitness Star Vietnam through the role of examiner with Minh Tu and Mau Thuy. This will be a long journey to find girls pursuing healthy lifestyles, positively influencing the community. I also accompany the competition Miss Universe Vietnam 2021 to find the beauty representative of the home country Miss Universe Future. In addition, I continue to work on inspirational startup plans and projects for young people. I always put my enthusiasm and accumulated experience to share with everyone. I choose a balance between work and home. I try to spend time taking care of my children and contributing to the community.

Since the company’s energy management system (Energy Management) came into operation in 2014, information on equipment operation and energy consumption has been reviewed and evaluated comprehensively. In fact, the plant’s lines are invested in many stages, asynchronous, so it is necessary to research to have appropriate solutions, especially related to synchronous lines and energy consumption, positive pressure. to use new techniques and technologies to use energy economically and effectively, improve the life of equipment and reduce costs.

In addition to internal issues such as promulgating regulations and instructions related to operating and using equipment to save energy, raising the user’s awareness into a cultural feature, the Company has implementing many renovation projects. Typically the major improvements are as follows:

Water supply system improvementPreviously, using only one upstream station and mixing pumps with different characteristics, causing energy loss, often having problems in the pump system and not meeting production needs well.

The renovation project is divided into 2 independent stations and connected in series: the upstream station reduces the pressure and increases the flow to supply part of the transmission line and the booster pump station is used for the required equipment. higher pressure. Each of these pumping stations includes a number of pumps with the same output and ensures the characteristics of parallel-connected pumps are equivalent and each station has 01 inverter pump as the main driver to automatically control the remaining pumps according to the applied pressure.

Always maintain the desired pressure in each area and optimize power consumption when demand changes to reduce power consumption in this area. The equipment’s age has also been markedly improved.

Install the inverter that controls the fan motor speed: To replace the flue air pressure control system with the previous inlet throttle.

When the power consumption is in proportion to the rate of 3 with the change of speed: N1 / N2 = (n1 / n2) 3 should show that in addition to the ability to respond to the fast system, the power consumption is very saving. After replacement, it was verified that power consumption decreased by more than 20% compared to before.

Replaced Russian 20/8 Piston Air Compressor: By Ingersoll-Rand R160 inverter controlled air compressor from USA to help adjust pressure as desired and save energy consumption.

Installation of low voltage compensation system: In addition to 6KV compensation, automatic compensation cabinets are installed for low voltage distribution stations; directly install compensation cabinets for AC motors> 22 KW, right near where the engine works; help to improve quality Electrical Power for the gear and reduce losses, reduce current through the switch for direct compensation motors.

Install the LEDs: For use areas with different requirements 150 lux, 200 lux, 300 lux, 500 lux, and have separate switches that are clearly communicated and specifically assigned.

Replace the oven ceiling with new materials: Previously made of heat-resistant concrete, there was a large heat loss with the temperature measured above 100 degrees C, the Company replaced with a new material with ceramic fiber, the temperature dropped to around 70 degrees Celsius and ensured ensure better life during work

Installation of aeration systems for filter towers: Helps to dispel the debris that clumps up that previous backwash is ineffective. Helping the filter towers always in effective working conditions, reducing pump power consumption due to reduced filter pressure and increasing the time to change filter material after 3 years instead of yearly as before, reducing production costs.

Renovation of replacement materials for cooling towers: The previous material is PVC with a short working time that must be replaced every 3 years and has a lot of dirt, reducing the heat exchange process is replaced by a Composite material (FRP) with better heat resistance. , no fouling and Splash Bar design to create turbulent and splashing flow for better exchange and cooling (the previous temperature through the Tower only decreased from 5-7 degrees, raised to 10-12 degrees C), reduce the power consumption for the cooling fan and the service life of the material is more than 10 years.

With a series of technical solutions above, energy audit results in 2018 show that energy management activities in Vietnam – Singapore Steel have achieved quite good indicators, power consumption and FO oil have both decreased. Specifically for electricity, from 2015 to 2020, auxiliary power will decrease from 21.70 Kwh / ton to 20.48 Kwh / ton of product; Electricity for production decreased from 97.97 KWh / ton product to below 86.79 KWh / ton of product. FO oil for billet baking in 2015 to 2020 will decrease from 32.50 liters / ton of products to 31.29 liters / ton of product.

Sharing experiences in energy saving activities at the Conference of the Ministry of Industry and Trade

Energy management activities, research and application of science, technology and new technology in the production process help reduce consumption and optimize expenditure. From there, it will contribute to improving productivity, product quality, reducing costs and increasing product competitiveness in the market.

Moreover, this also shows the sense of responsibility, increases creativity and professionalism in the work of the technical team of the Company. Using energy economically and efficiently is a very unique culture of NatSteelVina and this activity has been shared at a number of specialized conferences of the Ministry of Industry and Trade.

The company will continue to uphold its existing results and traditions to grow and prosper.
