We will pay close attention to basic management

Improve standardized operations

Starting from the adjustment of the converter load, through theoretical calculation, the total load of the converter is controlled according to the optimal furnace capacity ratio, which provides basic support for the stable operation of the converter. Formulate a series of operation instructions and special situation guidance, such as the comparison table of incoming materials, the comparison table of deoxidation alloy addition, and the gun level control curve, etc., independently develop the automatic control program of oxygen gun, and constantly promote the standardization of converter operation. In view of the problem that the parameters of the oxygen gun do not adapt to the actual situation on site, we timely communicate with relevant leaders and manufacturers to optimize the parameters of the oxygen gun nozzle, which plays an obvious role in improving the comprehensive index of the converter. Through the above comprehensive improvement, the operation foundation of the converter has been consolidated, the operation stability of the converter has been greatly improved, and it has become the core foundation for the improvement of various indicators in the steel mill, continuous stability, and continuous reduction of the comprehensive cost of billets.

Optimize production process

Reduce the cost of steel materials

Start from optimizing the production process control, implement the production organization mode centered on continuous casting, improve the production rhythm of single furnace and single machine, and gradually reduce the temperature of converter steel. Strengthen the utilization of hot metal temperature, combine with iron making under different iron consumption conditions to flexibly control the amount of iron produced in each package, achieve "one pot to the end", and reduce the loss of hot metal temperature; Self-made iron ladle capping, reduce the hot metal temperature loss before waiting for the furnace, after capping each ladle iron water temperature drop by about 15℃. The purpose of reducing the consumption of iron and steel material is to reduce the cost of iron and steel material by raising and lowering the temperature of molten iron and the temperature of steel.

Improve the utilization rate of solid waste

Reduce material consumption

Through continuous optimization of slag splashing control, scrap mixing and gun position control, the slag retention operation is gradually promoted, and the influence of dry dust removal on the slag retention operation is overcome, and the first step of solid waste utilization is realized. Through theoretical calculation and practical verification, we independently design the secondary utilization system of steel slag, and make a full set of equipment. In addition to using the iron in steel slag, we can also use the effective components such as calcium oxide, magnesium oxide and iron oxide in steel slag. Through slag retention operation and steel slag secondary utilization, the consumption of steel and solvent is further reduced.

Lifting converter terminal control

Compression alloy control range

By improving the operation level of the converter and making full use of the method of bomb prediction, the double hit rate of carbon temperature at the end point can be increased, the after-blowing can be reduced and the absorption rate of alloy can be increased. In order to reduce alloy consumption and ensure the quality of molten steel, we also promote the composition of molten steel very narrow range control, gradually narrow the composition range, reduce alloy waste; In order to control the slagging of steel, the slagging car is reformed to realize automatic slagging. In order to control the phosphorus return of the slag, the self-made throwing and feeding machine, adding white and gray surface to change the alkalinity of the slag, effectively control the phosphorus return of the slag. In addition, the recycled waste aluminum wire is fully used to replace the aluminum block for deoxidation, helping to reduce the alloy consumption.

Implement equipment renovation

We will strengthen energy conservation and reduce consumption

In view of the high cost of combustion power, the nitrogen equipment used in oxygen gun nitrogen sealing and evaporative cooling has been reformed according to the actual situation. Reroughing gas recovery pipeline; The waste water from the heat accumulator is connected to the boiler feed pool; The implementation of steam pipeline insulation and a series of renovation work, supplemented by the optimization of dust removal fan operating parameters, gas recovery operating parameters, steam recovery operating parameters, off-peak power consumption and strengthening energy management and control, reduce all kinds of waste and other comprehensive control, fuel power costs are greatly reduced.
