一、概述 1985年,洪都钢厂与英国戴维公司签订了引进改进型阿塞尔轧机主机线的合同,为了节省外汇投资,辅线设备由我厂自行设计研制。 改进型阿塞尔轧机自动化程度高,在生产过程中能实现快开和转角轧制,具有八十年代初期的装备水平。主机线与我厂φ90穿孔机相匹配,预计可年产4.5万吨热轧毛管,目前能为冷拔提供合理的管料,后部还可配置张力减径机,生产一部份热轧成品管,是
I. Overview In 1985, both Hongdu Steel and the British company David signed a contract to introduce a modified main line of Asiler rolling mills. In order to save foreign exchange investment, auxiliary equipment was designed and manufactured by our factory. The improved Assel mill has a high degree of automation and enables quick opening and corner rolling in the production process, with the equipment level of the early 1980s. The main line is matched with our factory φ90 piercing machine, it is estimated that it can produce 45,000 tons of hot-rolled capillary tubes. At present, it can provide reasonable pipe material for cold drawing. The rear part can also be equipped with tension reducing machine to produce a part of hot-rolled products Tube, yes
