How to deal with specific problems in rolling mill applications?
At present, new model CRM wire rolling mill equipment is an essential component in strip processing. Its road roller can improve the movement of the steel strip and the flatness of the cold rolls, thereby improving the efficiency of the use of the rolls, thereby increasing the service life of the rolls. However, in specific applications, the roller equipment is generally equipped with vicious oil seepage and pipe blocking compensation oil. At present, the reasons for common failures are closely combined with the basic principles of actual operation.
Due to the actual operation of the radial connection of the rolls, the steel joints are generated according to the actual operation of the rolls for maintenance, and the position sensor is installed on the winding roll to accurately measure the actual operation of the left and right rolls, which can improve the appearance of the strip. When it is necessary to control When bending the roll, the hydraulic transmission system changes the working pressure of the roll, so that the bending part of the positive tensile strain and positive pressure strength is released into the actual work roll and the turning groove of the wire rolling mill, and the holding method of the controller is changed.
In the disassembly display information of the moving motor shaft, the support point ring on the bending rod and the bearing end cover of the roller are seriously damaged, and the thickness is relatively thin, so the radial force in operation is cold-rolled azimuth drilling, and with the work When the pressure rollers are applied together to bear the azimuth angle of cold wire and strip rolling, the radial cutting speed will cause great damage to the hydraulic cylinder. According to the field application, the connecting cylinder on the transmission system side is a dovetail groove, which is used together with the roller bearing seat to make the bending The engine cylinder can reduce the radial drilling and release the large radial cutting speed when using the working pressure roll, which will reduce the service life of the bending roll on the actual operation side.
When the precision rolling mill roll is not at the zero position, the lock on the side of the machine equipment is not opened, and the machine equipment is not in place. In the preliminary design, the connecting rollers on the side of the module are checked with an automatic switch. Due to the actual effect of replacing the rollers and water vapor, it is basically impossible for the automatic switch to check the changes of the rollers, which are often generated during operation because the rollers are not blocked on the module side due to natural environment and time constraints.
