中心铸造

The center casting of the crusher adopts a standard wooden model, and the surface of the core is brushed with a special coating layer to prevent cracking and ensure that the surface of the casting is smooth and smooth;

When the central casting is melted, three samples are taken before the furnace, after the furnace and in the casting state, and the Germany spectrometer is used for testing to ensure that the composition is qualified;

In order to have a long service life, a special heat treatment process is used for the center casting to increase the service life and deformation resistance of the center casting.
