Raymond Mill Wear-resistant Casting Parts Research
Raymond Mill Wear-resistant Casting Parts Research
1.L Melting Process
CYK type high aluminium alloy cast iron melting inside Mid-frequency induction furnace. Melting temperature should reach to 1500~1550℃ to ensure the alloy melt and fully spread. To prevent casting organization coarse grains or appear cold-lap, wrinkled skin, casting temperature should be control in 1360 ~ 1380 ℃.
2. Casting Process
High chrome alloy cast iron material has the alloy content high, good fluidity, shrinkage, poor thermal conductivity of characteristic. So in design its casting modelling process, take directional solidification principle. And in order to strengthen the riser fill shrinkage effect of castings, impact hammer, counterattack by large and thick plate castings made poured rain type insulation riser cast method.
3. Heat Treatment
Heat treatment takes much ladder hyperbolic process, it including quenching and tempering. The process parameters and closely related section thickness, producing different casting, the parameters of different.
In addition, because of the materials alloy content high, thermal conductivity is poor, casting stress is great, and Raymond Mill wear-resistant casting parts are work under high stress. Therefore must be approved by eliminating stress heat treatment, to prevent early fracture.
Raymond Mill wear resistant parts important role is we should not only keep wearability but also to protect the Raymond Mill. Therefore, In Raymond Mill wear-resistant parts development process, from material to finished products, it mainly experienced L melting process, casting process, heat treatment. After these three process, we produced high quality
Raymond Mill wear-resistant parts.
