目前,要求棒材和线材轧机应具有生产效率高(40～90t/h)和生产产品范围广的生产能力。直到最近,这两种要求还未能取得一致:轧机不是在一定的产品范围时才能有高生产率,就是生产产品范围广时而生产率却很低。为了获得高生产率和重的盘卷,设备将朝着高速连轧机组发展,而且,其工艺规程和控制系统确保所需的冶金性能以及提供大的盘重,这就必须设计效率更高的轧机。特别是设备必须是更加经久耐用,以保证维修时间减至最少,尺寸容许公差小,减少表面缺陷。在轧机
Currently, bar and wire rod mills are required to have high production efficiency (40 ~ 90t / h) and a wide range of production capacity. Until recently, there was still a lack of agreement on these two requirements: a mill is not productive at a range of products, but produces a wide range of products at a time when productivity is low. In order to achieve high productivity and heavy coils, the equipment will move towards high-speed continuous rolling mills and its process regulations and control systems ensure the required metallurgical properties and provide a large weight of the pallet, necessitating the design of more efficient mills . In particular, the equipment must be more durable to ensure minimum maintenance time, small tolerances, and reduced surface defects. In the rolling mill
