After 1920, the production of low-carbon ferroalloy came to a new era in the context of development of high-quality steel and stainless steel. On one hand, on the basis of the process of producing metals by aluminothermy invented in 1898, aluminothermy was used for smelting of certain carbon-free ferroalloys and pure metals.
