某钢厂从国外引进热轧硅钢生产线精轧机前的边部加热器,该加热带钢的边部、辊道表面容易产生静电,将会引起辊道轴承座内轴承过热,导致轴承抱死的问题.辊道采用空心辊,辊身内部冷却,端部使用旋转接头、软管、绝缘套与外部管路连接.轴承座与辊道架连接处和辊道与电机连接的联轴器处加绝缘块、绝缘套、绝缘垫圈的方法,避免静电的产生,保证了生产的顺利进行.%In a hot rolled silicon steel production line,the abroad side heaters heat silicon steel,static electricity easily exist at heating strip edge,roller surface,which could leads bearing inner bearing overheating and a bearing lock issue.Roller adopts hollow roller,roller body internal cooling,end use rotary joint,hose,insulation sleeve and external connection.Roller bearing and roller frame joints and connected to the motor shaft coupling of insulation piece,bushing,insulation gasket,the method of avoiding the generation of static electricity,guarantee the production run smoothly.
