Generally, ferrochrome is produced by two production methods: high-carbon ferrochrome refining method and electric silicon thermal method. The electric silicon thermal method is to use silicon in silicon-chromium alloy to reduce chromium and iron oxides in the circuit under the condition of making alkaline slag in the circuit, so as to produce medium and low carbon ferrochrome.
High-carbon ferrochrome refining method is to use chromium ore to refine high-carbon ferrochrome. In addition, oxygen can be used to refine low-carbon ferrochrome. If chromium ore concentrate low-carbon ferrochrome is used, the slag in the refining furnace has a large viscosity and a high melting point. During the smelting process, the temperature must be very high. Therefore, the power consumption is high, the furnace lining life is short, and the carbon content is not easy to reduce. If oxygen is used to blow low-carbon ferrochrome, it has great advantages and many benefits, such as high productivity, low production cost, high recovery rate, etc.!
