随着铸造不锈钢件任务的不断增加,迫切需要找到切割这类铸件浇冒口的简便方法。我厂先后采用过下面的三种方法。1.电弧切割:应用了很长时间后因优质炭精棒供应不上,改用直径5毫米的炭素钢焊条作电极,能切割≤250毫米的不锈钢浇冒口,操作方便,容易掌握,但切割效率低,焊条消耗量大,且切出来的切口质量较差,所以后 With the increasing task of casting stainless steel parts, there is an urgent need to find a simple way to cut such castings riser. Our factory has adopted the following three methods. 1. Arc cutting: the application of a long time after the supply of high-quality carbon rod is not, the use of carbon steel rod diameter of 5mm for electrodes, can be cut ≤ 250 mm stainless steel pouring riser, easy to operate, easy to grasp, but Cutting efficiency is low, the electrode consumes a lot, and cut out the poor quality of the incision, so after
