The smelting methods of micro-carbon ferrochromium include electrosilicothermal method, hot melting method, etc. It is mainly used to improve the oxidation resistance and corrosion resistance of steel, so that the surface of the steel forms a layer of strongly adherent oxide film in the oxidizing atmosphere, and then Oxidation stops or the oxidation rate slows down. Microcarbon ferrochromium is mainly used to produce stainless steel, wear-resistant and heat-resistant steel.
The main uses of high carbon ferrochrome are:
1. Used as an alloying agent for circulating pearl steel, tool steel and high-speed steel with high carbon content to improve the hardenability of the steel and increase the wear resistance and hardness of the steel.
2. Used as an additive for cast iron to improve the wearability and hardness of cast iron, and at the same time make cast iron have good heat resistance;
3. Used as a slag-free method to produce silicon-chromium alloys and medium, low and micro carbon ferrochromium and chromium-containing raw materials;
4. Used as chromium-containing raw materials for the production of metallic chromium by electrolysis;
5. Used as raw materials for smelting stainless steel using oxygen blowing methods. .Smelting process of high carbon ferrochrome: The smelting methods of high carbon ferrochrome include blast furnace method, electric furnace method, plasma method, smelting reduction method, etc.
