Embodiment Construction
[0010] The present invention will be described in detail below in conjunction with the examples. Seven hot metal desulfurization stations are set up, which are respectively 1#~7# hot metal desulfurization stations; 1#~3# hot metal pretreatment station process flow: the molten iron tank is hoisted to the molten iron tipping car by the crane Up——Dump the tipping car to the injection position—Temperature measurement and sampling——Confirm the amount of powder sprayed—Lower the gun, spray——Elevate and clean the spray gun—Tip over the molten iron tank and remove slag——Reset the molten iron tank ——Temperature measurement and sampling——The end point of sulfur meets the requirements of the regulations, and the dump truck is driven out——The molten iron tank is waiting to be lifted away;
[0011] In the 4#~7# molten iron pretreatment station, the crane lifts the molten iron tank to the molten iron truck—the molten iron truck drives to the pouring station to connect the iron——after connect...
