西航集团公司机电石化设备厂承制的两套国产高速线材精轧机生产线日前在江苏永联钢厂热负荷试车成功，并顺利投入生产。技术，精轧机组均采用４５度侧交无扭式结构，每秒钟可轧制φ５．５—１４毫米的线材８４米，年产能力达到４０万吨。该机组具有结构紧凑、布局合理、转速快 Two sets of domestic high-speed wire finishing mill production lines contracted by the Xihang Group’s electromechanical petrochemical plant have recently been successfully tested in the thermal load test at the Jiangsu Yonglian Steel Plant and have been successfully put into production. The technology, the finishing rolling unit adopts the 45-degree side-crossing non-twisting structure, and can be used to roll 84 meters of φ5.5-14 mm per second, with an annual production capacity of 400,000 tons. The unit has a compact structure, reasonable layout, fast speed
