我厂大型工部的造型面积常感不够,尤其是地坑造型的产量更不能满足生产需要,因此大型铸件能否及时供应.已成为关键问题之一.我们按照苏联铸造专家莫沙可夫同志的建议,在大型铸件上采用沉箱造型法,并部分采用半永久型,经过试验,使地坑造型铸件的产量提高一倍左右,解决了我厂的关键问题. Large area of ​​our factory large part of the molding area often feel enough, especially the pit shape of the yield can not meet the production needs, so large-scale castings can be timely supply has become one of the key issues.We follow the Soviet Union casting expert Comkhusov Proposal, using caisson modeling method on large castings, and partly using semi-permanent type, after testing, so that the production of pit modeling castings doubled, to solve the key issues of our plant.
