我厂工具连工人、技术人员和干部发扬“自力更生”、“艰苦奋斗”的革命精神,运用唯物论的反映论,冲破因循守旧的框框,大胆实践,勇于实践,成功地制造了一台一百公斤无芯工频感应电炉,并实现了精密铸造的革新项目,开始投入生产。 精密铸造是机械工业中的先进工艺,采用这种工艺的优点主要是“吃废料”,它不仅把用过的废旧工具、料头等回炉熔化浇铸成新的工具,而且其钢材化学成份基本上不变,可节约大量钢材。并能浇铸出各种形状复杂的零件,达到少切削或无切削,大大减少机械加工工时。例如:车工气动卡盘卡爪,全年消耗2000个左右,过去需要经过车、钳、插、铣、磨、热等八个工序,机械加工工时2—2·5小时,材料采用优质工具钢,材料利用率仅达20％左右。 Our factory’s tools and even workers, technicians, and cadres have carried forward the revolutionary spirit of “self-reliance” and “hard work”. Using the materialistic theory of reflection, we have broken through the old-fashioned framework, boldly practiced and bravely practiced, and successfully manufactured a hundred kilograms of The core frequency induction furnace, and to achieve an innovative project of precision casting, began production. Precision casting is an advanced technology in the machinery industry. The advantages of using this process are mainly “eating waste”. It not only melts and converts used tools and material heads back into a new tool, but also does not have the chemical composition of steel. Change can save a lot of steel. And can cast a variety of complex shapes of parts, to achieve less cutting or no cutting, greatly reducing the machining time. For example, the lathes of pneumatic chucks consume about 2,000 a year. In the past, eight processes such as vehicles, clamps, inserts, milling, grinding, and heat were required. The machining time was 2-1⁄2 hours, and the material was made of high-quality tool steel. The material utilization rate is only about 20%.
