Refining basis body grain during the casting period, to improve the tooth pin’s strength and resistance abrasion ability

hits:1880    date:2015-08-30

  Generally speaking, during the normal production period of the excavator tooth pin and rubber, production manufacturers can choose some different methods to improvement the strength and resistance abrasion ability of the excavator tooth pin and rubber, for example, the common method is that during the casting process, production manufacturers can refining the grain of the basis body to gain this goal, and this method is very easy to operate, but also guarantee the finial result.

  Under the influence of the heating power, which produced by the casting process, the insert part would has some same organization with the welding heating effect zone, so this factor also can influence the resistance abrasion ability of the excavator tooth pin and rubber. So after the normal casting process, production manufacturers also need provide the suitable heat treatment to improve the basis body and organizations of the insert, use this method, also can improve the total use life of the excavator tooth pin and rubber.
