The digestibility of recarburizer manufacturers harms the composition of molten iron. The recarburizers with different proportions of silicon, manganese, carbon, and sulfur have very different digestibility during the whole process of melting in the heating furnace, such as silicon, manganese, carbon, and sulfur. The harm has been reduced successively. In the case that we use recarburizers, how to manipulate the digestibility of recarburizers, I will give you a detailed explanation of the semi-graphitized recarburizer below: high temperature asphalt
1. When the original carbon content increases by 0.1%, the digestibility of the carbonizing agent will decrease by 1%~2%.
2. When the original silicon content increases by 0.11%, the digestibility of the recarburizer will decrease by 3% to 4%;
3. When the original sulfur content increases by 0.1%, the carbonization agent digestibility will decrease by 1%~2%.
4. Every time the original manganese content increases by 0.1%, the digestibility of the carbonizing agent increases by 2% to 3%, which can be calculated according to this ratio.
When the original carbon content in the molten iron is high, the digestion and absorption rate of the carbonizing agent is slow, the intake is small, the ablation is relatively high, and the digestibility of the carbonizing agent is low under a certain melting moral bottom line.
When the original carbon content of the molten iron is low, the digestion and absorption rate of the carbonizing agent is fast, the intake is large, the relative ablation is low, and the digestibility of the carbonizing agent is high under a certain melting moral basis.
During ironmaking, because the molten steel is in the over-oxidation situation, the relative density of the recarburizer is low, so it cannot sink into the molten steel and react with the molten steel. The low utilization of carbon and the heavy objective deviations make the carbon content of steel grades in smelters low in accuracy everywhere, resulting in the production of stainless steel plates that are more brittle. The addition of recarburizers can solve the problem of carbon deficiency during ironmaking. Moreover, it can also reduce the composition of sulfur in steel. According to the above analysis, it is not too difficult to find out what will happen to the adverse effects of recarburizers if ironmaking does not work. Indeed, recarburizers are indispensable in ironmaking. In addition to adjusting the carbon content of molten steel to improve the quality of stainless steel plates, the non-ferrous metal raw materials will continue to reduce the cause of sulfur. It is reasonable to maintain everyone’s air and the physical and mental health of front-line workers. No recarburizer.
