The use of EAF allows steel to be made from 100% scrap metal raw material. This significantly reduces the energy required to make steel compared to ore primary steelmaking.Another benefit is flexibility: While blast furnaces cannot drastically change output and can run for years at a time, electric

Ferrochromium or ferrochromium (FeCr) is an iron alloy, an alloy of chromium and iron, usually containing 50-70% chromium. [1][2]Ferrochrome is produced from chromite ore by arc carbothermal reduction. Most of the global production comes from countries with rich domestic chromite resources such as S

A large amount of gas is produced in the production process of ferroalloy reduction electric furnace. When the open electric furnace is used for production, the gas burns into flue gas when encountering air, which is large and dusty. It is difficult to purify and is not conducive to energy recovery. It will pollute the environment for a long time, form public hazards and cause energy loss.

Main equipment for smelting ferroalloy. Ferroalloy electric furnaces are divided into reduction electric furnaces and refining electric furnaces. There are various types of electric furnace, such as electric furnace with open or semi arc operation, or electric furnace with submerged arc operation. Electric refining furnace is used to refine medium carbon, low carbon and micro carbon ferroalloys.

The electric furnace method is the main method for smelting continuous cast steel|iron alloy, and the output of electric furnace ferroalloy accounts for more than 70% of the total ferroalloy output. Electric furnaces can be divided into submerged arc furnaces and electric arc furnaces, also called r
