15000瓦水输发电机主轴锻件毛坯重量超过10吨,锻造时的夹持端直径约850毫米。由于我厂缺乏能切透400毫米以上的氧气切割炬,切割工作显得非常困难。我们采用内径为4毫米的紫铜管通以切割氧气代替切割炬伸入切口的方法,比较满意的解决了这个问题。 15000 watt generator spindle forging blank weight of more than 10 tons, forging clamping diameter of about 850 mm. Due to the lack of our factory can cut through 400 mm oxygen cutting torch, cutting work is very difficult. We use a diameter of 4 mm copper tube through cutting oxygen instead of cut into the incision into the cutting method, a more satisfactory solution to this problem.
