3t 电弧炉鼓轮机构是升降立柱及电极的重要导向装置。原设计鼓轮机构的轴承两端均采用普通的毛毡填料密封。随着填料磨损,粉尘进入轴承而造成轴承磨损,甚至出现轴承卡死致使鼓轮机构无法正常工作,加速升降立柱导轨磨损。设备在使用过程中一般又难以拆下清洗加油,鼓轮机构的工作性能如何, 3t electric arc furnace drum mechanism is an important guide lifting column and electrode. The original design of the drum bearing both ends of the bearing are used ordinary felt packing seal. With the filler wear, dust into the bearing caused by bearing wear and tear, and even bearing stuck so that the drum mechanism can not work properly, to accelerate the vertical column rail wear. Equipment in use is generally difficult to remove the cleaning refueling, how the performance of the drum mechanism,
