LZ—A型螺纹钢丝冷轧机是在吸取钢丝刻痕机和国外先进设备优点基础上研制而成的一种将低碳冷拔钢丝冷轧成螺纹钢丝的新设备。使用该机后,可节省钢材5～15％,缩短混凝土构件生产周期三分之一左右。该机具有结构合理、操作维修方便、体积小、重量轻、价格低(约5000元/台)、不需动力等特点。只要将该机装在拔丝机上就可同时完成拔丝和轧 LZ-A type thread steel cold rolling mill is developed on the basis of drawing the advantages of steel wire scoring machine and advanced equipment from abroad. It is a new type of equipment that cold-rolled low-carbon cold-drawn steel wire into thread steel wire. After using this machine, it can save 5 to 15% of steel and shorten the production cycle of concrete components by about one-third. The aircraft has a reasonable structure, easy operation and maintenance, small size, light weight, low price (about 5,000 yuan / Taiwan), without the need for power and so on. As long as the machine is installed on the wire drawing machine, wire drawing and rolling can be completed at the same time.
