上海第四冷轧带钢厂在毛主席“独立自主,自力更生”方针的指引下,在市冶金局党委的领导下,得到上海交通大学、上海科学技术情报研究所等单位的大力支持和协作,破除迷信,解放思想,冲破资本主义国家的技术垄断,经过两个多月的日夜奋战,试验成功中性电解去鳞新工艺,代替了酸洗法、喷丸法去除带钢表面的氧化铁皮。他们仅用了一个半月的时间,快速建成弯曲剥壳、中性电解去鳞、冷轧一条龙土机组,于1976年4月投人试生产,效果良好。中性电解去鳞新工艺采用中性无毒无害的硫酸钠水溶液作为电解质,根除了旧法对环境的污染。生产出来的普碳带钢没有脆性,可增大压下量,且 Under the guidance of Chairman Mao’s principle of “independence and self-reliance” and under the leadership of the party committee of Shanghai Metallurgical Bureau, Shanghai No. 4 Cold Rolled Strip Steel Works obtained strong support and cooperation from Shanghai Jiaotong University and Shanghai Scientific and Technological Information Institute, breaking the Superstition, emancipate the mind and break through the monopoly of capitalist countries, after more than two months of fighting day and night, the successful trial of neutral electrolysis to scale new process, instead of the pickling method, shot blasting to remove the oxide scale on the surface of the strip. In just one and a half months, they quickly built curved peeled, neutral electrolysis to scale, cold-rolled dragon unit, in April 1976 put into trial production, the effect is good. Neutral electrolytic descaling new technology using neutral non-toxic sodium sulfate aqueous solution as an electrolyte, eliminating the old law on the environment pollution. The produced carbon strip is not brittle, can increase the reduction, and
