What metallurgical effects are there on refining outside the furnace?
fine-tuning the components to reduce the chemical composition of the finished steel;
What is the effect of slag oxidation on the smelting process?
affecting dephosphorization, desulfurization, dephosphorization, not conducive to desulfurization
What is the cause of the lining erosion?
The role of high temperature heat flow. The high temperature action from the liquid metal and slag, especially in the primary reaction zone, may soften and melt the surface of the lining.
What is the role of the carbon-oxygen reaction during steel making?
Increase the steel-slag interface and accelerate the physical and chemical reactions.
Where does the steel making slag come from?
Where does the steel making slag come from? The main source of steel making slag is: oxides of various impurity elements (such as Si, Mn, P, etc.) contained in steel materials (hot metal, scrap steel);
Briefly describe the behavior of unburned pulverized coal in the blast furnace
