2300三辊劳特式中板轧机轧辊轴向固定装置,原设计采用三角形压板结构(如图1所示),使用中存在一定问题,不能有效地防止轧辊轴向窜动。1976年济南钢铁厂中板分厂对此进行了改造,使用5年,效果很好。 1.压板螺钉(M24)太细,上辊压板的三个螺钉受力不均,最下边一个受力大,经常断,中辊压板螺钉也有时断,更换螺钉影响作业时间。 2300 Three-roll Lutte plate mill roll axial fixation device, the original design using triangular pressure plate structure (Figure 1), there are some problems in use, can not effectively prevent the roll axial movement. In 1976, Jinan Iron and Steel Plant Plate Factory modified this, the use of 5 years, the effect is very good. 1. Platen screw (M24) is too thin. The three screws on the upper platen are under uneven force. The lowermost one is under large force and often broken. The middle platen screw is also sometimes broken, and the replacement of the screw can affect the working time.
