Therefore, the appropriate stirring time for molten iron should be when the recarburizer is completely dissolved. Refining slag can enable steelmaking enterprises to save raw materials in the production process, thereby achieving an effect of reducing production costs. Everyone knows that when ore is being smelted, a lot of resources are needed to be able to meet production requirements. The use of recarburizers has greatly reduced the utilization rate of coal and pig iron. This is only one aspect of it. On the other hand, increasing the use of recarburizers can greatly reduce resource development and reduce environmental pollution. The recarburizer is used in casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or eliminate the need for pig iron. The recarburizer is used in the smelting of the intermediate frequency electric furnace. It can be added to the middle and lower parts of the electric furnace according to the proportion or carbon equivalent requirements. The recovery rate can reach more than 95%. If the carbon content is insufficient to adjust the carbon content, the furnace should be cleaned first. In the slag, add recarburizer.
The carbon is dissolved and absorbed by heating the molten iron, electromagnetic stirring or manual stirring, and the recovery rate can be around 90. If the low-temperature recarburization process is adopted, that is, only a part of the charge is melted. When the molten iron temperature is low, all the carbon is increased. Agent. Add it to the molten iron at one time, and press it into the molten iron with a solid charge to prevent it from exposing the surface of the molten iron. This method can increase the carbon content of molten iron by more than 1.0%.
