bessemer process

Isaac Kremer/ September 9, 2018/ / 0 comments

Bessemer steel is made by pouring molten iron into a bottle-shaped vessel lined with refractory material, and blowing air through the iron until the carbon and silicon are burned out. The combustion of the carbon and silicon produces sufficient heat to keep the mass thoroughly melted. If the lining of the vessel is silicious or acid all the phosphorus and sulphur remain in the steel. By the Thomas Gilchrist method a basic lining is used, and the steel is made free of phosphorus. (Sturgis, 1900)
