For a reversible medium and heavy plate rolling mill, in the rolling process of different passes, if a steel plate deviates from the rolling central line of the rolling mill, the rolling of the rolling mill is unstable, the axial movement of a roller of the rolling mill is caused, the steel plate has the defects of camber, wave shape and the like in a mild state, and the steel plate scrapes a frame to cause rolling waste in a severe state, so that the steel plate is required to be symmetrical to the central line of the rolling mill in the rolling process of each pass.
Because the manipulator works in a high-strength and high-temperature environment for a long time, the manipulator has the problem that the opening degree is deviated, namely the error between the actual opening degree and the numerical value (reference zero calculation) of the theoretical manipulator opening degree is large; meanwhile, the lining plate of the push bench is worn to different degrees under the action of high load, and the actual center position of the push bench is deviated from the center position of the rolling mill, so that the push bench needs to be calibrated and corrected manually at regular intervals in the production process to overcome the problems. In the actual production process, the manual scale is generally adopted for on-site calibration and correction, and the calibration and correction formula has the advantages of large workload, unstable calibration and correction precision and low efficiency.
Therefore, the rapid calibration tool applied to the heavy and medium plate mill push bench is designed, so that the center alignment of the correction push bench can be calibrated rapidly, the deviation of the center alignment can be corrected, the operation is convenient, the stability of calibration and correction precision is good, and the rapid calibration tool has very high practical application value to technicians in the field.
