武汉钢铁公司七十年代引进的一七○○轧钢机,投产初期其大量设备备件基本上从国外购买,冶金部曾于一九七九年步署国内试制各类关键备件。其中冷轧厂镀锡机组的卷取机卷筒由上海冶金机械总厂按进口样机进行消化移殖研制。该卷筒为四棱锥液压涨缩结构,零件复杂,选材讲究、制作精度要求高,单卷承载能力为10吨,卷取速度高达40～400公尺/分,因卷取板材是厚度小于0.2毫米的镀锡软带材,对卷筒的运转平稳性及灵活性都有严格要求。该厂于一九八二年初成功的试制出第一台产品投入使用至今三年有
In the early 1970s, the 170-mill rolling mill imported by Wuhan Iron and Steel Company was basically purchased from abroad. In 1979, the Ministry of Metallurgy procured various key spare parts domestically. One of the cold-rolled tin coil unit winder drum by the Shanghai Metallurgical Machinery Plant according to the import of prototype digestion and development. The drum is a quadrangular pyramid hydraulic expansion structure, parts complex, pay attention to the selection of materials, production of high precision, single-roll carrying capacity of 10 tons, coiling speed of up to 40 to 400 meters / min, due to the thickness of the coiling plate is less than 0.2 Mm tin strip, on the smooth operation of the reel and flexibility have strict requirements. The factory successfully prototyped the first product in early 1982 and put it into use for three years now
