Main application of mining machinery casting
In production, the mining machinery should be cast and poured according to the principle of high temperature boiling and low temperature pouring. Because the extraction temperature of the molten metal is favorable for the complete melting of the inclusions, the slag floating, facilitating the slag removal and degassing, reducing the slag inclusion and pore defects of the machine tool casting; using a lower pouring temperature is beneficial to reduce the molten metal. Gas solubility, liquid shrinkage and high temperature metal liquid baking on the cavity surface to avoid defects such as pores, sand and shrinkage. Therefore, a lower pouring temperature is used as much as possible while ensuring that the mold cavity is filled.
There is also drum cleaning: mining machinery casting ordinary cleaning drum is a widely used cleaning equipment. The working principle is to remove the sand, burrs and scales on the surface of the casting by friction and collision between the castings and between the casting and the additional angle iron. The device has the advantages of simple structure, easy manufacture and good cleaning effect; the disadvantage is low productivity and high noise, and is suitable for small and medium-sized foundries.
