初轧厂1150初轧机是国内最大的开坯机之一,按设计能力日轧钢1万吨,年产330万吨。能轧制方坯、矩形坯及板坯,为大型厂、轧板厂、热轧厂提供坯料。但原轧制操作工艺制度为速度型,即高速小压下量轧制,结果轧制道次多、产量难以突破设计能力、且质量得不到保证、能量消耗也高。在推行“三全一化”作业的过程中,1986年三季度开始,初轧厂大胆试行了质量型轧制操作工艺制度,即适当降低轧制速度、增大压下量、减少轧制道次。新工艺的试行,取得了较好
Early rolling mill 1150 initial rolling mill is one of the largest open billet machine, according to the design capacity of rolling 10,000 tons, with an annual output of 3.3 million tons. Billets can be rolled, rectangular billet and slab, for large plants, rolling mill, hot-rolled mill to provide blank. However, the original rolling operation process system for the speed type, that is, high-speed rolling a small amount of rolling, the results of rolling passes and more difficult to break the yield of design capacity, and the quality can not be guaranteed, the energy consumption is also high. In the process of implementing the “three all-in-one” operation, beginning in the third quarter of 1986, the initial rolling mill boldly piloted the quality rolling operation process system, namely appropriately reducing the rolling speed, increasing the reduction and reducing the rolling road Times. Trial of the new technology, made better
