补充资料:冷作模具材料的原材料控制

模具钢制作的模具的性能必须通过严格的生产工艺来保证,对制作模具的原材料必须严格把关,防止模具因材料问题形成早期失效的热处理开裂等缺陷。


模具的原材料的控制从下列几方面进行:


1、宏观检验


化学成分对保证钢材的性能是决定性的,但成分合格,不能全面来说明钢材性能,由于钢材内部组织和成分的不均匀性,宏观检验在很大程度上补充了这方面的不足。


宏观检测可以观察钢的结晶情况,钢的连续性的破坏和某些成分的不均匀性。


标准《结构钢的低倍组织缺陷评级图》GB1979


宏观缺陷:


偏析               疏松                 夹杂                         缩孔
