Manufacturing Process of Cast Iron Castings

Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds (sand) or non-expendable molds (metal). Pouring can happen via gravity, low-pressure or vacuum. Controlling the pouring process becomes more important the more intricate the mold is.

Iron Making | Boundless World History

Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Unlike modern steel making, the process increased the amount of carbon in the iron.

Manufacture of Steel - Steel Manufacturing Process and Steps

Jun 06, 2017· The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
