There are four main metallurgical processes for the manufacture of finished steel products where the steel products can pick up defects. The defects picked up during these processes are (i) casting defects, (ii) rolling defects, (iii) forging defects, and (iv) welding defects. (Fig 1).These defects are described below.

To reduce runofmine to mill feed requires reduction in a series of stages. The physical size and power requirements of a crusher capable of reducing hard rock vary depending on the application. Extended experience in most crushing plants show that a minus 19MM (¾") rod mill feed can be and is being produced in three stages of crushing.

Steel Billets, Bars, Rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a threehigh mill with box passes, as shown in A in the figure. After a rectangular bloom is rolled ...

Mill scale is a mixture of iron oxides and other impurities formed in high temperatures. Rust is also a mixture of iron oxides but is created in the presence of moisture in everyday temperatures. For the same thickness, rust is far easier to remove than fresh scale. If scale is old, dry, and rusty, it is almost as easy to remove.
