Development of technology for removing manganese from ferrovanadium by sulphide slags and determination of its basic parameters

Purpose of the work: development of a technology for demanganization of ferrovanadium based on refining of metal melt from manganese by sulphide slags. The technology has undergone experimental industrial testing. The results of the work include the determination of laws of behaviour of metal and slag components when treating vanadium-containing metal by sulphide slags and the study of the concentration dependence of the sulphide slag adhesion to the ferrosilicovanadium melt and rate of evaporation of the sulphide phase. The results also include the determination of the optimum composition of the sulphide slag-forming mixture, duration of metal treatment, expenditure of the slag-forming materials, and technical, economical and ecological parameters of the technology of manganese removal from ferrovanadium by sulphide slags. The results of the work are being partially used at metallurgical plantsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
