The Production and Utilization of Two Smelting Processes for V-Ti Magnetite

Abstract

In this paper, two processes for V-Ti magnetite smelting were introduced, the processes respectively are the conventional blast furnace-BOF process and the high-profile rotary hearth furnace direct reduction technology. The two kinds of processes were introduced briefly, and the problems of the two processes in the production of V-Ti magnetite were analysed. The blast furnace-BOF process with the relatively perfect, large output, high energy efficiency can't make full use of Ti in the mineral resources, in this way, the resource was wasted and the environmental were polluted, and the existence of Ti in slag can also bring a series of problems in blast furnace production. Rotary hearth furnace direct reduction technology has the advantages of high reduction temperature, low product price, flexible selection for raw materials and reducing agent, while the large scale of equipment brings a series of problems to the production and design.
