Another way to create steel from pig iron is the Bessemer process, ... One is the huge availability of iron ore. The second is the accessibility of vast quantities of oil and coal to power the production of iron. Without iron and energy, we probably would not have gotten nearly as far as we have today.

The problem was again one of chemistry: the other iron producers used ore contaminated with phosphorus, which Bessemer later realized by careful chemical analysis of the ores and cast irons (after the event) prevented the production of high quality steel.

The process of metal locking began in the late 1930's as an option for repairing cast iron components and equipment on the Texas oil fields. The process was developed to provide a permanent, stress-free repair and utilized when the use of heat or open flame was limited.

At the conclusion of the cast, the taphole is replugged with clay. The area around the base of the

The Metallurgy of Cast Iron. Pure Iron is almost never used as a cast material because it is soft and weak. As the carbon content increases to 0.9%, so does hardness and strength.

of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace
