Hot rolled steel is to force the hot billet steel through rolls or molds to deform the billet steel and make it into I-beam, angle steel, flat steel, square steel, round steel, pipe, plate, etc. Due to the oxidation at high temperature, the surface shape of hot rolled steel is relatively rough.

The two more common alloys used by any steel foundry must be carbon steel and cast steel. While these terms are similar in nature, there are key differences in their meaning and their use in the sand casting process. Among all types of steel, there are different cast steel grades that determine the......

The size accuracy of the coating sand casting casting is CT7 ~ CT8, and the surface roughness RA value is 6.3 to 12.5 m. The formation of the forming sand of the membrane can reach the level of water glass melting mold casting process.
