我厂是一个拥有2,600多人的钢管专业化生产企业,主要产品是小口径无缝钢管、高频电焊管和镀锌钢管,其中小口径无缝钢管是以冷拔和冷轧管为主。生产小口径无缝钢管的主要设备有由我国自行设计制造的φ76毫米热轧机组一套、年产无缝管坯1.5万吨的φ76穿轧机组一套,20吨双链冷拔机四台,还有台式退火炉三座和酸洗精整等辅助设备。由于工艺设备落后,机减化程度低,因而产品质量差,生产成本高,无缝钢管只能出一般产品,作业率和产品合格率都很低。从1962年以来,我厂对φ76无缝机组进行了以提供冷
Our factory is a steel pipe specialized manufacturer with more than 2,600 people. The main products are small-diameter seamless steel pipe, high-frequency welded pipe and galvanized steel pipe. Among them, the small-caliber seamless steel pipe is mainly drawn and cold-rolled. The main equipment for the production of small-caliber seamless steel tubes is a set of φ76 mm hot-rolling mill designed and manufactured by our country, an annual output of φ76 piercing mill with a total output of 15,000 tons of seamless tube and four sets of 20-ton double- , As well as three desktop annealing furnace and pickling finishing and other auxiliary equipment. Due to the backward process equipment, low degree of machine reduction, resulting in poor product quality, high production costs, seamless steel pipe can only be a general product, operating rates and product qualification rates are very low. Since 1962, our factory has conducted φ76 seamless unit to provide cold
