Installation method of triangular base of continuous rolling mill in steel pipe plant

Abstract

The present invention discloses a steel pipe plant continuous rolling mill triangle base installation measurement tool and a steel pipe plant continuous rolling mill triangle base installation method. According to the tool, a horizontal plate is arranged on the top end of a V-shaped plate in a centered manner, the top surface of the horizontal plate is provided with two rolling center reference holes at intervals along the axial line, and the included angle of the V-shaped plate is a right angle. According to the method, the measurement tool is arranged on a new triangle base, the height from the bottom plane to the upper plane of the horizontal plate is measured, a center standard plate is arranged on the installation site, the old triangle base position data is mapped to the center standard plate through the measurement tool, the scale height of the old triangle base is measured, the old triangle base is disassembled and a new base slurry pillar is produced, the new triangle base is arranged in place, the vertical center position and the horizontal center position are adjusted according to the position information of the center standard plate to achieve a coinciding state, the scale height of the new triangle base is measured, the thickness of a gasket is adjusted and grinding is performed to make the scale height of the old triangle base and the scale height of the new triangle base consistent, and the position data is retested so as to complete the installation. With the tool and the method of the present invention, the installation precision of the triangle base are improved, the continuous production process requirements of the steel pipe rolling are met, and the normal operation of the continuous rolling mill is ensured.

Description

technical field [0001] The invention relates to a method for installing a triangular base of a continuous rolling mill in a steel pipe plant. Background technique [0002] The triangular base of the continuous rolling mill in the steel pipe factory is located on the 5.3-meter platform of the steel pipe factory. It is used to support eight continuous rolling mills. There are four continuous rolling mills on the left and right slopes of the triangular base. The rolling mill is locked on the triangular base to ensure the normal operation of the continuous rolling mill. Due to the harsh working conditions of the production site, the continuous erosion of the cooling water and scale of the rolls, the triangular base was severely corroded, damaged, and cracked, which resulted in the inability to effectively lock the continuous rolling stand, which made the center of the continuous rolling stand shift, which could not meet the continuous production requirements of the steel pipe fa...

AI Technical Summary

Problems solved by technology

The triangular base can effectively lock the continuous rolling stand, so that the error of the center line of the continuous rolling mill meets the requirements of continuous rolling, and can meet the rolling of steel pipes with a pass type of φ100mm to φ215mm; since the triangular base is in a triangular shape, it is necessary to replace and install the triangular base during the operation process During the process, the elevation and center position could not be measured, which resulted in the installation of the triangular base unable to meet the continuous production process requirements of steel pipe rolling, which affected the normal operation of the continuous rolling mill of the steel pipe plant
