一、冒口在铸钢件上的布置冒口在铸钢件上的位置正确与否对于获得良好的铸钢件和提高工艺出品率有重要意义。冒口位置不正确,即使用大量冒口补缩,也难以获得补缩良好的致密铸钢件。所以,冒口布置应注意以下几个问题: 1.要保证实现顺序凝固。因此,冒口应该置于铸钢件最后凝固的地方,也就是一些比较厚大、局部加厚和热量难以散失的地方。制定工艺方案时, First, the riser in the castings on the riser position on the cast steel is correct or not for obtaining a good steel castings and improve process yield is of great significance. Fool position is not correct, even with a large number of feeder riser, it is difficult to obtain a good complement of dense steel castings. Therefore, riser layout should pay attention to the following questions: 1. To ensure that the order of solidification. Therefore, riser should be placed in the final solidification of the castings, that is, some relatively thick, local thickening and heat loss is difficult to place. When developing process options,
