概述了几种常见的辊式破碎机齿板耐磨材料的种类、化学成分和组织及性能特点,提出了辊式破碎机齿板材料要根据破碎物料的种类和设备的情况选择不同的齿板材料及其制造工艺。对于单辊式破碎机齿板材料可选取碳钢和低合金钢,对于双辊式齿板材料,当齿板破碎物料时工作应力较大时,可选择高锰钢齿板材料,应力不大时可选择合金钢齿板或碳钢与高铬铸铁复合齿板或镶铸合金法。复合铸造和表面硬化处理是提高辊式破碎机齿板的使用寿命的最好的途径。
The types, chemical compositions, microstructure and properties of wear-resistant materials for roller crusher are summarized. It is proposed that different types of toothed plates should be selected according to the types of crushing materials and equipment Materials and manufacturing processes. For single roller crusher gear plate material can choose carbon steel and low alloy steel, for two-roller tooth plate material, when the tooth plate crushing material work stress is large, you can choose high manganese steel tooth plate material, stress is not big When the choice of alloy steel plate or carbon steel and high chromium cast iron composite tooth plate or alloy inlay. Compound casting and surface hardening treatment is the best way to improve the service life of the roller crusher tooth plate.
