EK系列自动化仪表是“六五”期间从日本引进的。这种仪表相当于世界70年代中后期水平,具有自动化程度高,灵敏度高,可靠性高,已在我国钢铁、化工、石油和国防工业中广泛使用,获得很高经济效益。EK仪表中的结构零部件都是用高精度冷拉易切削不锈钢棒材和丝材生产的,这种材料在我国仍是空白点。为加速EK仪表国产化,为提高我国仪表产品质量,我们研制成功了YoCr16Ni10MoCuCaS不锈钢冷拉棒材(φ6.5,φ8.5)和冷拉丝材(φ3.5,φ4.5)。北京电表厂用这种材料试制
EK Series Automation Instrumentation was introduced from Japan during the “Sixth Five-Year Plan” period. This instrument is equivalent to the world in the late 1970s, with a high degree of automation, high sensitivity, high reliability, has been widely used in China’s steel, chemical, petroleum and defense industries, access to high economic benefits. EK instrument structure components are made of high-precision cold-rolled stainless steel bar and wire cutting materials, this material is still a blank point in our country. In order to speed up the localization of EK instruments, in order to improve the quality of our instrumentation products, we successfully developed YoCr16Ni10MoCuCaS stainless steel cold-drawn rods (φ6.5, φ8.5) and cold-drawn wires (φ3.5, φ4.5).
