1.引言 冷轧带肋钢筋生产线的关键设备是Y型轧机,它对生产线的运行速度(轧速)、产品质量及生产成本具有举足轻重的作用。近几年,上海、南京等地先后从国外引进了几条生产线,其设计、制造及生产的操作都较先进。但从目前情况看,它存在着设备价格昂贵,投资大,操作维修复杂,软件技术对国外依赖性过大等问题。 从1985年起北京冶金设备研究院就进行Y
1. INTRODUCTION The key equipment of the cold rolled ribbed steel bar production line is the Y-type mill, which plays a decisive role in the running speed of the production line (rolling speed), product quality and production cost. In recent years, Shanghai, Nanjing and other places have introduced several production lines from abroad, the design, manufacture and production operations are more advanced. However, judging from the current situation, there are problems such as expensive equipment, large investment, complicated operation and maintenance, and excessive dependence on software technology. Since 1985, Beijing Metallurgical Equipment Research Institute conducted Y.
