青岛翰昌机械抛丸机护板的作用

抛丸机的抛丸器是有叶片、顶护板、侧护板、端护板、室体护板、定向套、分丸轮组成。其中护板有高铬铸铁件制造而成的。

那铸铁件在抛丸清理机中起到很大的作用的,铸铁件的热处理及它的特点是:
铸铁的金相学特点:铸铁与钢不同,铸铁由于石墨的存在以及金属基体和化学成分的差异,使铸铁的热处理具有特殊的性能1.铸铁的共析转变发生在一个相当宽的温度范围内。在这个温度范围内,存在着稳定平衡(铁素体-奥氏体-石墨烯)和介稳定平衡(铁素体-奥氏体-渗碳体系)。在共析温度范围内的不同温度,都对应着铁素体和奥氏体的不同平衡数量。这样,只要控制不同的加热温度和保温时间,就获得不同比例的铁素体和珠光体基体组织。因此,可在较大幅度内调整铸铁的力学性能。
