Method for adjusting housings outside of single stand reversible rolling mill

Abstract

The present invention relates to a method for adjusting a single stand reversible rolling mill, in particular to a method for adjusting housings outside the single stand reversible rolling mill, which comprises the following steps: a, determining that a housing base reaches assembly accuracy, and suspending the housings to correct positions; b, hanging a steel wire, checking vertical and transverse central lines of the rolling mill; c, connecting earphones to the vertical and transverse central lines of the rolling mill by lead wires; d, moving housings on a transmission side and an operation side towards the housing base direction on a discharge side respectively by a hydraulic jack to ensure that a bracket side of the housings is close to the lateral surface of the base on an outlet side, and moving a rail rest on an inlet side towards the outlet side; e, adjusting sizes of the housing rolling center and the transverse center of the rolling mill, and fastening a foundation bolt by 70 percent of a design torque; and f, hanging steel wires on housing windows and the rolling directions of the housings, and measuring the verticality and the horizontality of the windows and the rolling directions of the housings of the rolling mill. The method uses the steel wires and the earphones to ensure numerical reading, eliminates reading errors caused by visual errors of staff, and improves the assembly accuracy of equipment.

Description

technical field [0001] The invention relates to a single-stand reversible rolling mill, in particular to an adjustment method for a single-stand reversible rolling mill. Background technique [0002] In recent years, with the continuous construction and reconstruction of metallurgical steel rolling production lines, the products are developing towards high-end precision, and the installation accuracy of various rolling mills is also getting higher and higher. For the single-stand reversible rolling mill outer housing, it is important for the stability of the housing and the base, the contact between the reference plane of the base and the housing legs, the levelness of the housing bottom, the verticality in the window of the transmission side and the operation side, etc. The installation accuracy has extremely high requirements, the maximum tolerance requirement is ±0.5mm, and most requirements are 0.10mm / m; individual requirements are as high as 0.03mm / m (as shown in Table ...

Problems solved by technology

The accuracy of the micrometer used in the measurement is 0.01mm, so the key factor affecting the accuracy of the measurement reading is the measurement personnel, the measurement personnel are different, and the read data varies greatly, resulting in uncontrollable installation and adjustment deviations, and it is difficult to meet the requirements of equipment installation accuracy. thus affecting the production
