The slag chemistry of the process is also controlled to ensure that impurities such as silicon and phosphorus are removed from the metal. The process was developed in 1948 by Robert Durrer, using a refinement of the Bessemer converter where blowing of air is replaced with blowing oxygen.

The slag,Steelmaking - Wikipedia,Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome but the process of ancient steelmaking was lost in the West after the fall of the Western Roman Empire in the 5th century CE.What is Slag Glass? Price Guide and History,18/08/2020· Perhaps the most unique addition to the slag glass market during this period was Ohio-based maker Akro Agate, who had originally earned acclaim for making marbles. They transitioned in the 1930s into pressed slag glass designs, like these paired vases , to expand their reach (although, they preferred to call their pieces “multi-colors” rather than “slag glass”).Bessemer process - Wikipedia,In making crucible steel, the blister steel bars were broken into pieces and melted in small crucibles, each containing 20 kg or so. This produced higher quality crucible steel but increased the cost. The Bessemer process reduced the time needed to make steel of this quality to about half an hour while requiring only the coke needed initially to melt the pig iron.
