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...

Lost foam casting process of bimetal wear-resistant castings

Lost foam casting process is known as “new casting technology representing the 21st century” and “green engineering of casting” for its three characteristics of accurate forming, clean production and providing sufficient freedom for the structural design of wear-resistant castings. After lost foam casting, the foam model similar to the...
