轧管生产的现代技木是建立在许多辅助工序实现完全机械化和局部自动化的基础上,提高轧机生产率可采取如下措施达到:a,根据机座和主机列线上各另件的强度来确定最适宜的轧制速度和正确选择压下制度。δ,缩短机组工艺线辅助设备动作时间(缩短在工艺线上工作最紧张的机组辅助设备动作时间) 周期轧管机设备是在高速下进行工作的,因此它承受着不均匀的,并经常是撞击性的载荷,这种不稳定状态或称过渡状态一般是轧机工作的正常情况,要对周期轧机的工作情况给予正确的评述,必须知道作用在轧机主机列各部件上载荷的实际大小及变化情
The modern technology for the production of rolled pipe is based on the complete mechanization and partial automation of many auxiliary processes. To improve the productivity of the mill, the following measures can be taken: a. According to the strength of each part on the machine frame and main line Appropriate rolling speed and the right choice of depression system. δ, Shorten the working time of auxiliary equipment in the process line of the unit (shorten the working time of the auxiliary auxiliary equipment which is the most tense working in the process line) The periodic rolling mill equipment is working under high speed, so it suffers from uneven and often Impact load, this unstable or transitional state is generally the normal work of the mill, cyclical mill work to give the correct comments, we must know the role of the rolling mill in the various parts of the host load on the actual size and change situation
