Calcium ferrite, also known as pre-melting steelmaking slag-forming agent,
The performance and characteristics of calcium ferrite:
1. Calcium ferrite can accelerate the dissolution of lime, so it is no longer necessary to use fluorite to help the ferrite. The ferrite removal test of carbon-saturated Fe-C-P alloy by ferric calcium slag system at 1350 ° C under N 2 atmosphere is found. Compared with the oxide dephosphorization agent, the calcium dephosphorization agent has less oxygen consumption and has good dephosphorization kinetic conditions, realizes fluorine-free steelmaking, reduces lining erosion, and reduces environmental pollution.
Second, calcium ferrite is mainly composed of high-calcium composite materials, with uniform product composition and stable quality. Because the slag is good, the smelting is stable, and the molten steel is splashed, the steel industry can increase the yield by about 1%.
3. Calcium ferrite effectively improves the converter smelting process, rapidly slag, and efficiently dephosphorizes the rate, thereby shortening the smelting time.
