破碎机锤头浇注系统设计不正确时

破碎机锤头浇注系统设计不正确时,金属液产生涡流便会裹入气体从而导致气孔的产生;铸造锤头时排气不良,气体不能从铸型中排出也会导致气孔的产生这就要求我们在浇注时严格控制浇注温度,并且在浇注时均匀不能中断,为了便于铸型排气,可以采用倾斜浇注。
When the pouring system of hammer head of crusher is not designed correctly, the eddy current generated by metal liquid will be wrapped in gas, which will lead to the generation of gas holes; when the hammer head is cast, the exhaust gas is not good, and the gas can not be discharged from the casting mold will also lead to the generation of gas holes, which requires us to strictly control the pouring temperature during pouring, and even during pouring can not be interrupted. In order to facilitate the exhaust of the casting mould, inclined pouring can be used.
破碎机锤头在经过使用后都会出现不同程度的磨损,由于进行低冲击的作业条件,锤头表层加工硬化效果也会加剧,锤头的磨损是指在机械力的作用下,金属锤头表面逐渐脱离母体,导致锤头的性能发生变化,磨损对锤头的使用寿命影响最大。
Hammer head of crusher will be worn to varying degrees after use. Because of the low impact operation conditions, the hardening effect of the surface of the hammer head will be intensified. The wear of the hammer head means that under the action of mechanical force, the surface of the metal hammer head gradually separates from its parent body, resulting in changes in the performance of the hammer head, which is caused by wear and tear. The service life has the greatest impact.
