本锤头制作工艺采用单一的高铬铸铁材料,对其化学成分进行优化设计和加入多种合金进行变质处理。同时在锤头的中心部位安放Ω形圆钢骨架,用消失模铸造方法一次成形。按此工艺生产的锤头,不但硬度高,耐磨性好,而且在使用中不断裂,其使用寿命是高锰钢的2倍以上。为解决单一高铬铸铁中小型锤式破碎机锤头容易产生断裂的问题,提供了一种新的铸造工艺。
The hammer production process using a single high-chromium cast iron material, the chemical composition of the optimal design and add a variety of alloys for deterioration. At the same time in the center of the hammer placed omega-shaped round steel skeleton, with a lost foam casting method once formed. According to the production of the hammer, not only high hardness, good wear resistance, and does not break in use, its service life is high manganese steel more than 2 times. In order to solve the single high chromium cast iron hammer small hammer crusher prone to fracture problem, providing a new casting process.
