提高颚式破碎机齿板耐磨性的铸造工艺方法

Improve Casting Process of Jaw Crusher Teeth Plate Wear Resistance

齿板是鄂式破碎机中最主要的易损件,其使用寿命直接关系到颚式破碎机的工作效率和生产成本,用于制造颚式破碎机齿板的材料主要是高锰钢,颚式破碎机齿板在中等冲击应力条件下工作,不能充分发挥加工硬化性能,造成齿板不耐磨。为了增加齿板的耐磨性,改进后的铸造工艺是以高锰钢为主要材料,在齿板各个破碎齿上镶铸硬质合金棒,并采用消失模铸造方法和铸造余热热处理等工艺。

The tooth plate of jaw crusher is the main wearing parts, the workingefficiency and cost of production, life is directly related to the jaw crusher current,used in the manufacture of jaw crusher toothed plate is the main materials of highmanganese steel, because of jaw crusher teeth plate belongs to medium impactstress working conditions, work hardening cannot be brought into full play, is the main cause of the tooth plate is not wearable. In order to increase the wear resistance of the tooth plate,casting the improved process or in the highmanganese steel as the main material, each broken teeth in tooth plate cast hard alloy rod, and uses the method of vanishing and casting remained heat treatmentof die casting process.
