有色金属铸件在清理工序上,特别是最后一道工序——浇冒口的切割,一直是个老大难问题。过去,我厂有色金属铸件的浇冒口切除,采用手工锯或锯床,操作中工人劳动强度大,且生产效率低。在毛主席亲自制订的“鞍钢宪法”指引下,在厂党支部领导下,组织工人、干部、技术人员三结合,试制成功了一台悬臂回转式砂轮切割机。该机经一年多来的使用考验表明,性能良好,满足生产要求。它的使用,大大降低了工人的劳动强度,改善了劳 Non-ferrous metal castings in the cleaning process, especially the last one process - Riser mouth cutting, has always been a chronic problem. In the past, I plant non-ferrous metal castings Riser cut, the use of hand saws or sawing machine, the operation of workers in labor-intensive, and low production efficiency. Under the guidance of the “Anshan Iron and Steel Constitution”, which was formulated by Chairman Mao personally, under the leadership of the Factory Party Branch, workers and cadres and technicians were organized into three pilot companies to successfully manufacture a cantilever rotary wheel cutting machine. The machine after more than a year of tests showed that good performance, to meet production requirements. Its use has greatly reduced the labor intensity of workers and improved labor
