Description of the Related Art In recent years, a method using a shot blast machine, which has no problem of pollution such as acid waste solution, has been widely used for removing oxide scale generated on the surface of steel materials. In addition, the composition of the oxide scale of carbon steel material generally depends on the surface layer of the base metal, Fe
It is known that it is composed of o, Fe 3 O 4 and Fe 2 O 3 , and that its composition ratio and scale thickness vary depending on the steel material manufacturing conditions such as hot or cold rolling temperature. Therefore, the composition scale and the scale thickness of the oxidation scale of the steel material differ depending on the manufacturer of the steel material and the type of the steel material. However, such oxide scales may or may not be easily scale-removed by blasting depending on the composition ratio and the scale thickness. On the other hand, in the case of steel makers, it is the actual situation that these oxide scales are removed under the same blast conditions.
