2020-8-15 Bessemer process, the first method discovered for mass-producing steel. Though named after Sir Henry Bessemer, the process evolved from the contributions of many investigators before it could be used commercially. It was apparently conceived independently and almost concurrently by Bessemer

What was the purpose of the Bessemer process? –
Why was the Bessemer steel process invented? The Bessemer Steel Process was a method of producing high-quality steel by shooting air into molten steel to burn off carbon and other impurities. Both Bessemer and Kelly were responding to a pressing need to refine the methods of manufacturing steel so it would be entirely reliable.

A Short History of Steel and the Bessemer Process
2018-7-22 Steel was still unproven as a structural metal and production was slow and costly. That was until 1856 when Henry Bessemer came up with a more effective way to introduce oxygen into molten iron to reduce the carbon content. Now known as the Bessemer Process, Bessemer designed a pear-shaped receptacle—referred to as a converter—in which iron ...

Bessemer process and similar topics
Process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
