在轧管生产中,为了平衡穿孔机、均整机和自动轧管机的沉重接轴,采用着弹簧式和重锤式的平衡装置。弹簧装置在工作中不十分可靠。它们被装在机架的凹槽里,轧机工作时破坏弹簧间隙的氧化皮会落入其内。为保证轧机工作辊所需的倾斜角度,轧机必须长时的停车以便从平衡装置的支柱下面排除氧化皮。 In the rolling pipe production, in order to balance the piercing machine, both the whole machine and automatic pipe rolling machine heavy shaft, using a spring-type and heavy hammer balancing device. Spring device is not very reliable at work. They are housed in the groove of the frame and the oxidation of the spring clearances falls into the mill during operation. In order to ensure the desired roll angle of the work rolls of the rolling mill, the rolling mill must stop for a long period of time in order to remove scale from under the struts of the balancing device.
