一般厂对铸件检查工作是做得不够的,检查科以为铸件在最後完工时检查就可以了。铸件生产过程很复杂,涉及到化学、金属学,金相组织等各方面。特别是目前铸件种类很多,有些铸铁的物理性能,如抗拉力可达50公斤/公厘2(已接近低碳钢的性能)。铸件操作是多方面的,检查员有好些工艺过 General factory inspection of castings is not done enough, the inspection section that the casting is completed in the final inspection on it. Casting production process is very complex, involving chemistry, metallurgy, microstructure and other aspects. In particular, there are many kinds of castings currently available. Some cast irons have physical properties such as tensile strength up to 50 kg / mm 2 (close to that of mild steel). Casting operations are multifaceted, inspectors have better craftsmanship
