Melting process of wear-resistant pump body castings

1. Selection of C and Si For wear-resistant pump body castings, the selection of C content should not only ensure the requirement of sufficient graphitization, but also take into account the risk of graphite floating in the casting process. Therefore ω (C) 3.65% ~ 3.80%; Si strongly promotes graphitization,...

Technical requirements for wear-resistant pump body castings

The wear-resistant pump body casting is the main part of the pumping system. As the pumping system used in mining machinery and equipment contains hard particles, during the pumping process, due to vortex centrifugation and gravity, the high-density hard particles move close to the cavity wall, thereby causing erosion...

Casting process of wear-resistant pump body

Furan resin sand is used for molding, and the 24h strength of sand mold (core) is controlled σ b≥1.0 MPa; The rigidity of the sand box used for molding should be good, and the sand consumption of the mold should be large enough to ensure the overall rigidity of...
