过去我厂盐浴炉用的铸铁坩埚的造型是采用车板法,泥心也是用车板车出,这种方法配型时间长,生产效率低。在生产大跃进中,坩埚的需要量增加很多,如果仍然采用这种落后的造型方法,是无法满足生产需要的。杨坤森老师傅在生产大跃进的鼓舞下开动脑筋想出了先进的造型方法。改进后的造型方法如图1,是用铁样(如图2)直接来造型。先用铁样春出 In the past, the shape of the cast iron crucible used in our salt bath furnace was car plate method, and the mud heart was also made out of the car plate car. This method has long configuration time and low production efficiency. During the Great Leap Forward, the demand for crucibles increased a lot. If this backward modeling method is still used, it will not be able to meet production needs. Yang Kun Sen master cheer in the production of the Great Leap Forward brains came up with advanced modeling methods. Improved modeling method shown in Figure 1, is to use iron-like (Figure 2) to shape. First spring out with iron
