Damage Cause Analysis and Improvement of Injection Lance For High Vanadium Ferrovanadium
Through analyzing the reasons for lance damage during the smelting process of high vanadium iron lean slag in Chengsteel Company,it is concluded that the main factors affecting the service life of the injection lance:the body of the refractory burning and slag erosion,drastic changes in temperature cycle stress damage.Industrial tests have shown that the electric melting magnesia as aggregate,magnesium chloride as binder,adding steel fiber as refractory made injection lance,can significantly improve the Injection lance fire and good thermal shock stability and improve the service life of the Injection lance,reduce the production cost.
