Micro carbon residue, commonly known as "MCR", is a laboratory test used to determine the amount of carbonaceous residue formed after petroleum materials are evaporated and pyrolyzed under certain conditions. This test is used to provide some indication of the coking propensity of the material. [1][

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.
