Seek the "source" of cost reduction, gather the "force" of efficiency, grasp the details, reduce costs, promote business... The companies of Hebei Xinda Group firmly establish the concept of "all costs are controllable and reduced", deeply dig the potential of cost reduction and efficiency improvement, take production and operation work as the main line, and strive to carry out various quality and efficiency improvement work, aiming at the key and precise force, so that cost reduction and efficiency improvement are deeply integrated with production work.

How to win in the "change" and how to dig the "gold" mine in the details has become a major issue in front of every manager. Hebei Xinda Iron and Steel Group Co., Ltd. raw material factory white ash workshop is in such a background, to the director Li Lianjun lean development production concept as guidance, assistant director Zhou Limin's high standards and strict requirements as a drive, workshop director Xu Yao's exploration and innovation as a pioneer, jointly write a brilliant chapter of multiple measures, improve quality and efficiency.

Underscreen recycling

Screening benefit

As a key part of the whole production process, the production efficiency and cost control of the white ash workshop of the raw material plant are directly related to the overall benefit of the enterprise. In the face of constant changes in the market environment and the pressure of cost control, managers at all levels of the white ash workshop know that only exploration and innovation can be invincible in the fierce market competition.

Under the leadership of Xu Yao, the director of the workshop, the management team of the white ash workshop first made an in-depth analysis of the current production situation. They found that although the standard enterprises have their own advantages, but copy copy is not the fundamental way to solve the problem, to achieve the real cost reduction and efficiency, but also need to find a breakthrough point from their own, explore the potential, improve production efficiency, so a vigorous cost reduction and efficiency action in the white and gray workshop.

Xu Yao led the team to carry out in-depth research and discussion on the large amount of screening material produced by the Maltz white ash workshop every day. They found that up to 40% of the 9mm-30mm limestone in these undersifts can be used only after being sold directly to mining companies and processed into limestone powder, which undoubtedly increases the cost of enterprises. In order to solve this problem, Xu Yao led the team to brainstorm and organize a technical transformation, they added a set of vibrating screen equipment, the bottom of the screen is transferred to the material shed, the use of 9mm vertical teeth screen for screening. After sifting, 9mm-30mm of greystone is successfully recovered and digested internally, and the remaining undersifted material is resold. This initiative not only reduces the cost of purchasing limestone powder, but also improves the utilization of resources, and it is estimated that the cost of saving the enterprise is as high as 8.7834 million yuan/year.

Equipment system improvement

Conversion efficiency

As the saying goes: "If you want to do something good, you must first benefit its tool", equipment is the fundamental guarantee of production and operation, while ensuring the quality and quantity of production tasks, the white gray workshop always pays attention to the equipment situation. In order to improve work efficiency, the management team of the white ash workshop has optimized the denitration system of the rotary kiln. They found that the current denitration system uses a rake soot blower for continuous automatic soot blowing, although it can maintain the normal operation of the denitration system, but each denitration system consumes up to 1400m³/h of air pressure, and the cost is high. In order to reduce this cost, the secondary directors of the white ash workshop combined with professional technicians to conduct an improvement proposal exercise. After in-depth research and analysis, they decided to change the rake type soot blower from automatic to manual operation, setting the cut-off point of the pressure difference of each layer of catalyst to 250pa, and manually blowing ash when the catalyst layer pressure difference is higher than 250pa. This improvement initiative not only reduces the air pressure consumption, but also improves the operational efficiency of the denitration system. It is estimated that this improvement activity is expected to reduce the cost by 408,000 yuan/year.

In addition, the White Ash plant management team also found another way to reduce costs - increasing the temperature of the imported flue gas. In daily work, they found that by increasing the temperature of the flue gas imported from denitrification, they could not only meet the production requirements, but also reduce the gas consumption. Therefore, they actively tried to improve the relationship between the temperature of imported flue gas and the reduction of gas consumption. After many tests and adjustments, it was found that when the temperature of imported flue gas reached 200 degrees, the gas consumption was significantly reduced, and the consumption of tons of ash was reduced from 90m³/t to 52m³/t. The implementation of this measure not only improved the production efficiency, but also, according to estimates, It also reduces the cost of 792,000 yuan/year for enterprises.

The innovative measures and cost reduction and efficiency actions of the white ash workshop of the raw material factory not only improve the economic efficiency and competitiveness of the enterprise, but also set an example for the entire industry. Their successful experience shows that only continuous innovation, continuous exploration, and multiple measures can achieve real cost reduction and efficiency and sustainable development. In the coming days, the white ash workshop will continue to closely unite under the leadership of the factory, to promote the optimization and upgrading of the production process with higher standards and more stringent requirements, and contribute to the long-term development of the enterprise.

Don't neglect to save, save a little into a million. The completion of the overall work objectives must be guaranteed by the completion of the indicators of each unit, the steel mill will continue to take the initiative to pressure on the basis of the courage to take the initiative, implement the main responsibility one by one, firmly focus on the budget indicators, keep an eye on the time node, wall chart combat, step by step, steady and steady. With the courage to emancipate the mind and self-revolution, we will consistently promote the work of reducing costs and increasing efficiency, continue to improve technical and economic indicators, and work together to live a game of chess to contribute to the work of reducing costs!
