通过设置预埋件的方法解决了高铬耐蚀铸铁件攻丝困难的问题,并对设置预埋件时要求的零件结构和设计方法进行论述。预埋件设计时,先根据经验对其尺寸进行初步设计,然后参照铸钢件熔合内冷铁的设计方法进行校核,根据校核结果对预埋件尺寸进行修正。 By setting the embedded parts method to solve the problem of high chromium corrosion of cast iron parts tapping difficult, and set the embedded parts required parts structure and design methods are discussed. Embedded parts design, the first preliminary design based on experience of its size, and then refer to the design of cast steel fused iron within the design method of verification, according to the results of the correction of embedded parts size correction.
