我厂650毫米轧机自投产以来,摆台经常发生事故,据78年1月至81年5月统计,因摆台事故,停机时间长达406小时,影响产量1.4万吨,减少利润370万元,从投产开始计算经济损失就更大了。摆台现存在的主要问题是:1.设备事故多,关键部件损坏较严重:投产以来主轴根部断裂一根,摆台拨叉断裂6件,每年烧坏主电机3～4台,连杆螺丝每月断3～4次,拨叉铜滑块磨损快,两个月左右需更换一次。其原因是制动不稳,冲击载荷
Since our plant 650mm mill has been put into operation, it has frequent accidents on the table. According to the statistics from January 1978 to May 1981, the shutdown time of up to 406 hours resulted in an output of 14,000 tons and a profit reduction of 3.7 million yuan , The economic loss from the start of production is even greater. The main existing problems are: 1. Equipment accidents, the more serious damage to key components: Put into operation since the spindle root rupture, swing fork fork 6, each year the main motor burn 3 to 4 units, connecting rod screws Broken 3 to 4 times a month, fork copper wear fast, about two months to be replaced once. The reason is unstable braking, impact load
