通过凸模铸件生产摸索,将原工艺4个角1/4补块改为1/2补块,以解决长方形变形问题;采用冷热冒口联合使用及加大大平面加工量措施,以解决大平面夹渣、气孔问题;操作上增加测量4个角垂直度和表面尺寸。经过上述工艺措施生产,彻底解决了铸件变形及夹渣、气孔问题。
Through the casting mold production groping, the original technology 4 corner 1/4 patch to 1/2 patch, to solve the problem of rectangular deformation; the use of hot and cold riser joint use and increase large plane processing measures to solve large Flat slag, stomatal problems; operation to increase the measurement of 4 verticality and surface size. After the above process measures production, completely solve the casting deformation and slag, porosity problems.
