锤头制造的工艺

锤头的生产工艺是否合理严重影响破碎机的工作效率与生产能力,因此严格的控制锤头的生产工艺,才能能锤头质量更稳定。 锤头大多数是选用高铬耐磨铸铁,高铬铸铁具有良好的流动性、较大的收缩性、因此可延长锤头的使用寿命。 怎样才能使锤头的使用时间更长呢,锤头的制造工艺也是决定其使用寿命的关键因素,如果锤头表面或内部制造中存在缺陷,如缩孔、裂纹、穿晶等,不仅会降低锤头性能,甚至会造成锤头断裂。 因此,在锤头生产中必须制定合理的铸造工艺和热处理工艺,例如高铬锤头,应采用立浇和合理使用外冷铁,并严格控制浇铸温度等措施,这样可使锤头在铸造有良好的凝固顺序和补缩条件,进而得到致密内部组织,并减弱晶粒粗大现象。 锤头的热处理工艺则决定了其力学性能的实现和碳化物的分布形态,由于在锤头的成分中都含有一定量的铬和其它合金元素,因此如何使这些合金元素形成硬质点碳化物的作用充分发挥出来,也是制定热处理工艺时考虑的一个因素。 The production technology of hammerhead seriously affects the working efficiency and production capacity of the crusher, so the production process of the hammer head is strictly controlled, so that the quality of the hammer head is more stable. Most of the hammer head is high chromium wear resistant cast iron, high chromium cast iron has good fluidity, large shrinkage, so can prolong the service life of hammer head. How to make the use time of hammer head is longer, the manufacture technology of hammer head is to determine the key factors of its service life, and if the hammer head surface or internal manufacturing flaws, such as shrinkage cavity and crack, transgranular, will not only reduce the hammer head performance, even cause hammer head fracture. Therefore, in the hammer firstborn during must formulate reasonable casting process and heat treatment process, such as high chrome hammer, vertical casting should be adopted and the rational use of cold iron, and strictly controlling the pouring temperature, which can make the hammer head in casting solidification sequence and feeding conditions, and then get dense internal organization, and weakened phenomenon of coarse grains. Hammer head of the realization of the heat treatment process determines their mechanical properties and the distribution of the carbide morphology, because in the composition of hammer head contain a certain amount of chromium and other alloying elements, so how to make the alloy elements to form carbide hard spots role into full play, and make heat treatment process to consider a factor.
