摘要

The present invention is used as a material erosion inflow of molten steel slag line portion of the vessel wall of the ladle steelmaking process and in invasive and have a high sex content relates to ladle slag composition for carbon -containing basic refractory material inlet line , which is 58-72 % by weight of magnesia clinker , 20 to 25 % by weight spinel clinker powder , granular or pulverized coke, artificial graphite 3-7 % by weight of calcined alumina, 5-10 wt% ultra fine powder with a basic composition , and thus the second extrapolated pulverized silica flower , B4C, SiC, sodium hexametaphosphate , to more than one tenth the weight % of the basic composition of citric acid so will not add to the mix .
