氧化和脱碳是合金元素与气体介质相互反应和物理扩散过程中所产生的一种铸造缺陷。防止这种缺陷的产生有二种方法:一、用强制冷却的方法防止铸件铸态脱碳我厂精铸的35钢、
Oxidation and decarburization are alloying defects that occur during the interaction and physical diffusion of alloying elements and gaseous media. There are two ways to prevent such defects: First, the method of forced cooling to prevent casting as-cast decarburization I cast 35 steel,
