Description:

Calcium ferrite slag arises from their high capacity to absorb acidic impurities (e.g., arsenic and antimony) while presenting a wide, homogeneous liquid area when mixed with iron oxides. These two aspects partly solve troublesome magnetite precipitation during the smelting and converting of copper concentrates and reduce bath contamination in the electrolytic refineries.
Calcium ferrite is used as deoxidizer, desulfuration, dephosphorization in steelmaking. which
can rise refining effective highly and ladle' using time. 

Characteristic：

1、 Slagging speed. Because of the slag conditions improve, lime use efficiency, can save lime
consumption.
2、 Due to good slag, created good dephosphorization in the furnace conditions. The purposes of prophase dephosphorization, increase the rate of dephosphorization 3 ~ 5%.
3、 Type the premelting steelmaking slag agent (calcium ferrite) can accelerate the dissolution of limestone, and therefore do not need to reoccupy fluorite to melt and achieve fluorine-free steelmaking; Lining erosion reduction, to reduce the environmental pollution
4、 In smelting slag is good, smooth, reduce spillage molten steel, which can improve the steel liquid yield is about 1%.
5、 Shorten the melting time. The rapidness of slag, high efficiency dephosphorization rate, smelting time can be shortened.
