Research on refining slag-making process of high alumina vanadium clay
In view of the problems of poor slagging effect,large deviation between final slag composition and target,high total Fe content in slag and high cost in slag-making process of Xingang Special Steel Plant.Based on the principle of chemical reaction,smelting and sintering at high temperature can react high alumina vanadium clay with other raw materials to produce refining slag.After comparing the experimental results,it was found that using high alumina vanadium clay instead of fluorite and refining slag can solve the problems such as poor slagging effect in the slag-making process,improve the deviation of final slag composition,lower the total oxygen content of steel billets,higher cleanliness,better fluidity of molten steel.In addition,this improvement not only reduces the cost of slag production,but also helps to reduce slag erosion of the furnace lining refractory material and reduces the volatilization of fluoride,thus reduces the pollution of the environment.
