石景山钢铁公司转炉车间新安装的可拆式D型三吨碱性转炉(这种转炉是利用电动机通过减速箱转动炉体)在投入生产时,炉体不能转动。经职工研究与改进,这个问题已经得到解决,使转炉顺利投入生产,采取的措施如下:一、减少轴和轴瓦的接触面新安装的转炉的实心轴和空心轴与轴瓦之间几乎有120°接触角(见图1),摩擦力很大。在烤炉期间 Shijingshan Iron and Steel Company converter workshop newly installed demountable D-type three-ton alkaline converter (this converter is the use of electric motors through the gearbox to rotate the furnace) when put into production, the furnace can not rotate. After the research and improvement of the staff and workers, this problem has been solved and the converter is successfully put into production. The measures are as follows: 1. Reduce the contact surface between shaft and bearing bush The solid shaft and hollow shaft of newly installed converter have almost 120 ° Contact angle (see Figure 1), great friction. During the oven
