General Steel Making The Cementation Process
The cementation process of making steel is also called the converting process. This process consists in impregnating bars of wrought iron or soft steel with carbon, at a temperature below its melting point, and was used (chiefly in England) for the production of high carbon bars to be employed in the manufacture of crucible steel or shear steel.

Cementation process Wikipedia
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.
