LOW CARBON-FERROCHROMIUM MANUFACTURING METHOD BY USING CONTINUOUS THERMIT REACTION

摘要

The present invention relates to a process for producing low-carbon ferrochromium,;Introducing scrap iron or ferrochrome into an electric furnace to produce a molten metal; Mixing molten chrome ore powder with a reducing agent powder containing no carbon to produce molten ferrochrome melted by a thermite reaction; And removing the slag produced by the thermite reaction. The present invention relates to a method for producing low-carbon ferrochromium,;Particularly, in the present invention, the use of coke as a reducing agent in the prior art can reduce costs by using waste or by-products such as aluminum dross, magnesium cutting liquor, and ferrosilicon powder as waste generated in an aluminum melting furnace, It is possible to reduce the heating cost by continuously supplying the molten metal in the electric furnace in advance and to inject ferrochromium in a molten state directly into the mold to provide ferrochromium having a uniform and uniform component content.;Thermite Reaction, Briquette, Aluminum Cutting Snow, Aluminum Abrasive
