Micro Carbon Ferro-Chrome

Micro carbon ferrochrome contains about 30% gas (mainly N₂ and H₂), which floats at the interface between molten steel and slag during steelmaking, leading to increased chromium losses and reduced recovery rates. The vacuum treatment process reduces the gas content in the alloy, minimizing metal losses caused by bubbles.

Ferrochrome is classified into four types based on carbon content: high-carbon ferrochrome, medium-carbon ferrochrome, low-carbon ferrochrome, and micro carbon ferrochrome. High-carbon ferrochrome enhances the hardenability and wear resistance of steel, while micro carbon ferrochrome is used as an alloying element in steelmaking.

The Bessemer method, also known as the "thermal exchange method," is an external desiliconization process that uses a silicon-based reducing agent to reduce the chromium and iron from the chrome ore-lime melt in a reaction tank, resulting in a low-carbon product with a chromium recovery rate of up to 95%. Compared to the electric silicon thermal method, the silicon utilization rate is close to 100%, and it avoids contamination from carbon electrodes.

The electric silicon thermal method involves melting chrome ore, lime, and silicon-chromium alloy in an electric arc furnace, with the required heat energy provided by electric heating and the oxidation reaction of silicon. This method effectively produces refined ferrochrome.

The vacuum solid decarburization method uses oxidants to oxidize carbides in high-carbon ferrochrome in a vacuum electric resistance furnace to produce micro carbon ferrochrome, primarily used as an alloying additive in steelmaking. The unit energy consumption of the product ranges from 3600 kWh/t to 3700 kWh/t, with a qualification rate of over 98%.
