本发明为铁水脱硫(如高炉铁水炉外脱硫)提供了一种可喷射的脱硫粉剂。该脱硫剂包括由焙烧石灰、冶金萤石及石油焦组成的渣生成成分,镁粉与渣生成成分合成一种可向铁水喷射的粉剂脱硫剂。
The present invention provides a sprayable desulfurization powder for hot metal desulfurization (such as blast furnace hot metal furnace desulfurization). The desulfurization agent comprises slag generation components consisting of calcined lime, metallurgical fluorite and petroleum coke, and the magnesium oxide powder and the slag generated components synthesize a powder desulfurization agent capable of being sprayed onto the molten iron.
