On New Year’s Day 2022, an epidemic struck, posing severe challenges to the company’s normal production and operations.
Production management departments such as the Manufacturing Management Department, Equipment Department, Energy and Environmental Protection Department carefully sorted out the problems encountered in each production line, combined with equipment maintenance and elimination of deficiencies, optimized production planning, strengthened on-site control, and organized production meticulously. Under the unprecedented high-load normal production and high-quality specific ratio production mode, the production organization team has done a full system analysis to improve the effective operation rate of continuous casting, conduct targeted research, and effectively solve the iron and steel balance bottleneck. At present, the daily consumption of molten iron for steelmaking reaches 13,800 tons. The supply and production team focuses on ensuring the supply of materials, purchasing raw materials, and material balance in advance, formulating emergency plans, strengthening abnormal handling, and coordinating changes in conditions and ensuring supply of peripheral raw materials, fuels, intermediate products, and energy media. The production and sales team actively responded to the severe restrictions on product delivery and logistics, realized 24-hour production-delivery linkage, dynamically adjusted production plans, maximized the warehouse storage capacity, and effectively supported stable and efficient production throughout the entire process.
The coking plant actively overcomes the impact of the epidemic and implements “three shifts” operations for on-the-job personnel to ensure normal and stable production. It solves the shortage of raw materials through various channels, strengthens production and equipment management, and ensures the continuous supply of dry quenched coke and stable and mature coke quality. Meet blast furnace production needs.
The ironmaking plant adheres to the purpose of “stability, consolidation and improvement” to ensure smooth blast furnace production. The No. 1 blast furnace maintains low energy consumption and stable production, optimizes the internal operating system, improves refined operation capabilities, and has a daily output of more than 7,000 tons many times; the No. 2 blast furnace has overcome many difficulties since the thermal load test, gradually optimized the operating system and indicators, and solved the problem through grouting Due to the problem of tapping iron splashing, output continued to rise in March, and the daily output at the end of the month stabilized at more than 6,700 tons.
Taking the balance of iron and steel as the starting point, the steelmaking plant strengthens lean management, optimizes key indicators such as operating procedures, steel material consumption, and scrap steel material types, dynamically organizes the connection balance of iron and steel, and implements equipment shortages in a planned manner to achieve stable and orderly production. Cost and quality are stable and controlled. Among them, the number of continuous casting furnaces of No. 2 continuous casting machine in January reached 204, breaking the record of 182 furnaces; the number of continuous casting furnaces in February reached 223, setting a new high.
The hot rolling mill actively plays the leading role of party building, focusing on stable and high production, scientifically arranges rolling plans, standardizes the roll changing process, cooperates with steel coil shipments, and ensures the safe operation of the coil warehouse; actively promotes standardized operations, increases the proportion of full hot charging, and timely Eliminate equipment hazards and improve the stable operation of equipment. The comprehensive hot charging rate of slabs has exceeded 85% for two consecutive months. The total hot charging of slabs in the first quarter reached 1.0408 million tons, achieving a significant increase in efficiency and carbon reduction.
On the basis of achieving a “good start” in the first quarter, Ningbo Steel will continue to follow the work requirements of Hangzhou Iron and Steel Group’s “Strive for Reform and Development”, closely focus on the annual production and operation tasks, and continue to do a good job in epidemic prevention and control and production operations, striving towards “green We are moving towards the high-quality development goal of “, low-carbon, smart and high-end”.
