摘要
济钢第一小型厂针对车间横列式轧机故障多、轧制速度受限等缺陷进行设备改造，通过改进７～９＃轧机列的伸缩方轴、十字接轴及轧机位置、改造轧机的移动装置、调换电机等，使横列轧机故障时间由６２．７５ｈ缩短为１０ｈ，故障率下降９０％，轧机转速提高８％～１０％，提高产量约１０％．
Because of the transverse arrangement mills has some defects,such as high accident ratio and restricted rolling speed,etc,the equipment reforming is done in No.1 small section rolling steel plant of Jinan Iron and Steel Group General Corporation.Through reforming of stretching out and drawing back square shaft of No.7～9 rolling mills,cross jointing shaft and reforming moving device and changing motor of rolling mill the accident time of the mill is decreased to 10 hours from 62 75 hours,the accident ratio is decreased 90%,the rotational speed of rolling mill is increased by a factor of 8%～10%,and the production capacity is increased by a factor of 10%.
