cementation process of steelmaking

General Steel Making - The Cementation Process

The cementation process is a now-obsolete technique for making steel with the carburization of iron. Unlike modern steelmaking it increased the amount of carbon in the iron. It was apparently developed before the 17th century. The process probably originated in Bohemia in the 16th century and was in use in Bavaria in the early 1600's.

The cementation process is an obsolete technology for making steel by carburization of iron. Unlike modern steelmaking, it increased the amount of carbon in the iron. It was apparently developed before the 17th century. Derwentcote Steel Furnace, built in 1720, is the earliest surviving example of a cementation furnace. Another example in the UK is the cementation furnace in Doncaster Street, Sheffield.

Steelmaking Process - an overview | ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

Oct 09, 2020 · Alternately, the carbon can be introduced after the iron has been formed into a bar in a process known as cementation (also called case hardening or forge hardening, although the phrase ‘case hardening‘ can also mean effectively ‘surface hardening’ making it an imprecise term). Once iron is heated above roughly 900°C (or, in visual terms, a ‘red heat’), it will begin to absorb ...
