颚式破碎机是矿山破碎石料的设备,其颚板是该设备的主要易损件,国内外多采用高锰钢材质生产各种颚式破碎机颚板。由于钢液温度高,对砂型的加热时间长,故对300kg以上的高锰钢铸件,多数厂家采用工艺较复杂的干砂型、水玻璃自硬砂、表干涂料砂等工艺铸造,这样增大了铸造成本,延长了生产周期。为简化铸造工艺,降低生产成本,我们采用天然 Jaw crusher is mine crushed stone equipment, its jaw is the main wearing parts of the device, at home and abroad to use high manganese steel production of jaw crusher jaw. As the molten steel temperature is high, the heating time on the sand is long, so for high manganese steel castings over 300kg, most manufacturers use the process of more complex dry sand, water glass, hard sand, dry sand and other table casting process casting, so increase Casting costs, extending the production cycle. To simplify the casting process, reduce production costs, we use natural
