冶金设备在高速、重载、高温与多尘等恶劣条件下作业,故障多、备件消耗量大已是管理工作中的一个主要问题。 鞍钢第一初轧厂φ1100初轧机是30年代的老设备,其压下装置见图1。 这种压下装置的压下速度快(65/98mm/s),动作频繁(13～17次/min),生产过程中承受的轧制负荷大(一般为57.9～120.6×10~5N)。在轧钢时压下装置要同时承受轧制压力和上轧辊平衡力等多种作用力,各传动件的受力状态复杂。在调整压下装置时,工况条件差,特别在超负荷生产时,零件事故多、备
Metallurgical equipment in high speed, heavy load, high temperature and dust and other harsh conditions of operation, failure and spare parts consumption has been a major management problem. The initial rolling mill of Anshan Iron and Steel Company φ1100 is the old equipment of the 1930s, the depressing device shown in Figure 1. The pressing device has a high reduction speed (65 / 98mm / s) and frequent movements (13-17 times / min). The rolling load during the production process is large (typically 57.9-120.6x10-5N). During rolling, the pressing device must bear the multiple forces such as the rolling pressure and the balance force of the upper roller at the same time, and the stress state of each transmission member is complicated. In adjusting the pressure device, the working conditions are poor, especially in the overload of production, parts and more accidents, preparation
