"Two down and one up"
Strive to build a low-cost, high-quality leading edge
In the face of the complex macroeconomic environment and the severe situation of the steel industry, I think the key to survival is to reduce costs, and the core of getting better is quality. I will lead all the cadres and staff of Hebei Xinda Iron and Steel Group Co., Ltd. to implement the "ultimate cost reduction" strategic deployment, break the habitual thinking, deepen the standard to find the difference, pursue process progress, continue to optimize the charge structure, deoxidation mode, etc., to promote the main economic indicators to improve, achieve the maximum benefit of the whole line, and strive to complete the annual production goals and tasks.
Focus on efficient cooperation
Promote process cost reduction
Reduce the consumption of steel and ferrous materials. According to the heat balance, the slag is reasonably added in the converter, and the double slag is reasonably used in the silicon high manganese blast furnace to avoid large spatter. Strengthen the communication of continuous casting in converter, control the temperature reasonably according to the time of pressing steel, control the pouring of large and medium ladle, divide the pouring stop and block the flow of billet, reduce the cutting head and tail of billet. Develop plans to improve the converter one-down rate and carbon temperature hit rate, refine rewards and punishments, enhance the awareness of key positions of the converter, and improve the one-down rate. In the furnace where the temperature is high, the cold material such as steel bar cutting is used to adjust the temperature after the furnace to reduce the temperature of nitrogen in the furnace and improve the metal recovery rate. Increase the recycling of self-circulating slag steel, large iron, steel beans, self-produced slag steel back to eat more than 18kg/t; The continuous casting platform uses a special slag basin to collect all kinds of scrap steel, and the iron-bearing material consumption is reduced by 3.02kg/t compared with the plan.
Reduce alloy consumption. Combined with the test data of the quality measurement department, the performance of the product is tracked, and the composition of the steel grade is controlled in the lower limit. Discussed with the Technical Department and Quality Measurement Department about Q195 using SiAL iron to replace part of the aluminum block to reduce the deoxidation cost, and tracked the subsequent rolling situation and quality feedback. Through professional training, improve the level of component control, ensure the qualified rate of finished internal control components, and improve the operation level of steel and metal workers by using the lever of reward and punishment. Standardize the alloy structure of each steel type of converter and the use of deoxidizer, strictly in accordance with the operation points or technical requirements, strengthen the operation when steel, pay attention to the addition of alloy and carburizing auxiliary materials, do a good job in slag retaining operation, and create good conditions for saving the amount of alloy and carburizing auxiliary materials. Pay close attention to the composition temperature of molten iron, adjust the amount of scrap steel, prevent the phenomenon of low temperature after blowing, affecting the absorption rate of alloy and carburized auxiliary materials; Strengthen the operation of converter, increase the end point C content, reduce the oxidation of molten steel. Through the above measures, the consumption of all-steel alloy is reduced by 0.46kg/t compared with the plan.
Reduce fuel power consumption. The first is to reduce power consumption, pay attention to the peak valley flat price, such as the production preparation section in the valley period to fill the silo; The medium pressure pump of the unit is transformed into a closed circuit pump, which can save 190,000 yuan per month; Control the use of air conditioning in the high voltage distribution room, prevent equipment idling during maintenance, and reduce the power consumption by 2.96kwh/t compared with the plan. The second is to reduce the gas consumption of blast furnace, and reduce the number of online ladle baking under the premise of meeting the production requirements. The third is to reduce nitrogen consumption, the furnace with a large amount of slag, under the premise of ensuring the requirements of furnace protection, first pour out part of the slag and then splash the slag, shorten the splashing time, nitrogen consumption is reduced by 1.2m³/t compared with the same period in previous years.
Improve the pass rate of casting billet. Implement the quality management requirements of the company, do a good job of key quality equipment control, and focus on the stability of continuous casting equipment. By controlling the amount of slag under the converter, improving the internal control ratio of molten steel composition and the pass rate of molten steel process temperature, the pass rate of casting billet in the steel mill is increased by 0.11% compared with the plan.
Focus on improvement and innovation
Promote production cost reduction
Steel mills adhere to the improvement and innovation as the lead, closely follow the theme of cost reduction and efficiency, all-round and multi-level to carry out independent improvement activities, dredging and solving the blocked points and difficulties that restrict production, and complete more than 100 proposals for improvement throughout the year.
Among them, the automatic deburring program of slab heat delivery roller is designed, which improves the integrity of slab process, and the number of abnormal holes is almost zero, reducing the consumption of burring machine blade more than 300,000 yuan/year. The slag car was improved by adding a big shovel, and 200 beams were installed on site to strengthen the strength and improve the production operation rate, with an annual comprehensive effect of about 5.126 million yuan. The closed circuit water transformation of the water pump unit changed the motor with the original closed circuit pump power of 630KW and the head of more than 1600 li to the converter medium pressure pump motor with the power of 250KW and the head of more than 560 li of water, saving about 3 million yuan of electricity every year. Converter aggregate bin internal vertical plate transformation, reduce manufacturing, replacement, maintenance costs of 160,000 yuan. Slab cutting car chain to guide rail, expected annual effect of 500,000 yuan.
Manage by accounting
Promote overall efficiency improvement
In terms of production organization, adhere to the production policy of "stable continuous casting as the center, converter furnace condition as the basis, equipment as the guarantee", take standardized operations as the starting point, standardize operation details, and strictly control all kinds of accidents. Strengthen production organization and coordination, do the converter "four unequal", compress the standard auxiliary production time.
In terms of converter production, ladle is covered in the whole process to achieve red envelope steel, reduce the steel temperature, and ensure the low temperature and fast casting of continuous casting. Converter strive not to pour the furnace forward, direct out of steel, refining across the arrangement of a crane to ensure rapid replacement of steel car slag basin. Reasonable adjustment of scrap ratio, eliminate scrap block degree, unreasonable size of the impact of scrap. The weight of a single bag of molten iron in the furnace is stable, and it is consistent with the loading amount of the converter to ensure that a can is finished; When loading iron, the scrap car and the iron crowning car are called to the furnace in time, and the iron can be loaded when the furnace is shaken to the position. Avoid red slag overflow during steel drawing; Strict management of slag-blocking car, slag-blocking resistant material, slag-blocking operation, improve the slag-blocking effect; Speed up the transfer of steel slag, and ensure the recycling of slag pond. Evaluate the hit rate of assessment, pass rate and other indicators, improve the hit rate of molten steel, eliminate waste.
In terms of continuous casting production, adhere to the temperature control in the package, control the superheat of the package, and close communication with the scheduling and converter, reduce the number of isosteel and steel pressing, and eliminate steel leakage accidents. Continuous casting pull down to clean the nozzle in time to ensure the cooling effect; Ensure opening degree to prevent bulging and center line cracks at too fast pulling speed.
In terms of equipment management, implement daily spot check, improve the spot check record, know the operating status of the equipment thoroughly, and eliminate all kinds of equipment problems that may affect production. Regular sorting of spare parts, spare parts, combined with the actual situation of production safety and equipment operation, with the repair of old and waste as the starting point, to ensure that key parts have spare parts, common spare parts self-repair and self-reform, extend the service life of equipment.
