在生产大跃进中,要提高大型机床的产量,关键问题在于大型铸件造型面积不足,地坑造型生产效率太低。铸造专家莫沙可夫同志建议我们采用沉箱造型法来提高大型铸件的产量,经试验证明这种方法是先进的,它可以使劳动生产率提高一倍左右,解决了我厂的关键问题。 In the Great Leap Forward of Production, to raise the output of large-scale machine tools, the key problem is that the area of ​​large casting is not enough and the production efficiency of pit modeling is too low. Casting expert Comkhodov suggested that we use the caisson modeling method to increase the production of large castings. The tests prove that this method is advanced and it can double the labor productivity and solve the key problems of our factory.
