我厂为了保证轧钢车间生产的热轧等边角钢以及钴车问生产的氧化钴、硫酸钻、环琬酸钴、无水亚硫酸钠等出口产品质量,采用了国际先进标准,因而使产品进入了国际市场,赢得了信誉,深受用户欢迎。我厂轧钢车间从一九六三年开始生产中型热轧等边角钢,工艺设备不断完善,轧制工艺基本实现了机械化,产品规格逐步实现了系列化,各种规格产品分别采用不同规格钢坯,固定轧制道次。制定了严于冶金部颁 YB166—65、YB170—63标准要求的厂内控苏 Q/J·N G B301—81标准,并以此内控标准要求组织生产。具体技术条件对比如下:1.截面尺寸允许偏差(毫米)规定如下:
In order to ensure the quality of export products such as the hot rolled equilateral angle steel produced by the rolling mill and cobalt car, the quality of the exported products such as cobalt oxide, cobalt sulfate, cobalt naphthenate and anhydrous sodium sulfite has been adopted by our factory, so the products have entered the international Market, won the reputation, welcomed by users. Our factory rolling mill started to produce medium-sized hot-rolled equilateral angle steel in 1963. The process equipment was continuously improved and the rolling process was basically mechanized. The product specifications were gradually realized serially. Various specifications of the products were adopted with different specifications of steel billets, Fixed rolling pass. Developed strictly in accordance with the Ministry of Metallurgy Ministry issued YB166-65, YB170-63 standard factory control Su Q / J · N G B301-81 standards, and internal control standards require production. Comparison of specific technical conditions are as follows: 1. Cross section size tolerance (mm) as follows:
