自从跃进再跃进的高潮到来,各项生产指标都飞跃猛晋,跑在生产前线的铸件产量也成倍地增加。要究成这艰巨而光荣的任务,便不能停留在老一套的生产方式上,而必须在铸工工艺上大闹技术革命及推广先进经验。我厂自采用新措施后,生产效率就显著提高,铸件日产量也能符合跃进计划的需要。但是铸件的清理工作仍旧是侬靠人工用冷泵枪操作,劳动强度高,生产效率低,这就使清砂工作逐渐跟不上铸件的日产量,使铸件越积越多,不能及时供应加工车间的需 Since the climax of the leap forward and the leap forward, various production indicators have leapfrogged, and the output of castings that run on the production front has also multiplied. To study this arduous and glorious task, we must not stop at the old production method. We must make a big technological revolution and promote advanced experience in the casting process. Since our factory adopted new measures, the production efficiency has been significantly improved, and the daily output of castings can also meet the needs of the leap forward. However, the cleaning of castings still depends on the use of artificial cold pump guns, which leads to high labor intensity and low production efficiency. As a result, the sand removal work gradually fails to keep up with the daily output of castings, making the castings more and more and unable to be processed in time. Workshop needs
