一、概述我单位一九七○年前从钢厂引入了碱腐蚀工艺,代替大部分耐热合金钢零件手工吹砂。但因碱腐蚀工艺生产环境差,影响了工人的身体健康。为了改善劳动条件、保证产品质量、提高生产率,我们建立了碱腐蚀自动线,采用纸带继电器式顺序控制。经过几个月的运行,证明性能良好,满足了生产要求。 First, an overview of my unit before the introduction of the alkali corrosion process from 1970 to 1970, instead of most of the heat-resistant alloy steel parts by hand blowing sand. However, due to alkali corrosion process poor production environment, affecting the health of workers. In order to improve the working conditions, to ensure product quality, increase productivity, we have established an automatic caustic corrosion line, the use of paper tape relay-type sequence control. After several months of operation, it proved that the performance is good and meets the production requirements.
