东北轻合金有限责任公司102分厂热扎机大钨金瓦从开工生产一直用苏联备件。从1964年开始由铸造车间浇注。由于技术不过关,每次浇挂后都出现大面积粘结不牢须进行焊补或重新浇挂。每次热扎检修都须更新更换浇挂。2005年车间针对浇挂大钨金瓦质量不过关和生产效率低,以提高质量提高效率进行技术攻关,组织人员进行工艺试验。经过两个月工艺试验,浇挂成功。2007年春节检修时检查仍然完好不需更换。实践证明质量达到苏联进口水平,生产效率提高一倍。
Northeast Light Alloy Co., Ltd. 102 factory hot 扎 machine big tungsten Jinwa production started from the Soviet Union has been using spare parts. From 1964 pouring from the foundry. However, due to technology, but after each pouring a large area of ?? cement are not bonded or re-dumped. Each hot-rod inspection must be updated replacement hanging. 2005 workshop for pouring hanging large tungsten tile quality and low production efficiency, to improve the quality and efficiency of technical research, organize personnel to carry out technological tests. After two months of technology test, pouring hanging success. 2007 Spring Festival maintenance inspection is still intact without replacement. Practice has proved that the quality of the Soviet Union to import the level of production efficiency doubled.
