iron and steel

Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

Advantages of the Continuous Casting Process

Unlike continuous casting, the extrusion process of aluminum, iron, and steel rams one metal against another with excessive force so it is forced into a mold. Extrusion is great for manufacturers who need basic bars and rods, but if you are seeking more complex parts, extrusion will only get you so far.

Direct Reduced Iron and its Production Processes – IspatGuru

Mar 16, 2013Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

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.
