Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the existing traditional construction methods, and provide a debugging method that can effectively solve the influence of the non-processed surface of the rolling mill base on the levelness detection of the rolling mill base and the detection of the parallelism of the adjacent rolling mill exit base

Embodiment Construction

[0032] The present invention is further illustrated below by specific examples.

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] A method for adjusting archways and bases of continuous rolling mills using contour blocks, including

[0035] Step 1, Equal height block 2 selection:

[0036] Select the equal height block 2 to be used for erecting the level ruler and use in conjunction with the inner diameter micrometer. 10-20 blocks of two types of equal height blocks are purchased and processed to facilitate the simultaneous adjustment of the base of the multi-frame archway. Before using the contour block 2, use an outer micrometer with an accuracy level of 0.01mm to measure the thickness of each part of the single contour block 2 and the stacked thickness of multiple blocks. The contour block 2 used for erecting the ruler is 20mm wide x 10mm thick x 150mm long, and the contour block 2 used ...

Abstract

The invention relates to the field of multi-frame mill installation, in particular to a tandem mill board and a base adjusting method thereof. The method is characterized by comprising the following steps: (1) equal height blocks are prepared; (2) the equal height blocks are erected; (3) the longitudinal centers of mill bases are aligned by using the equal height blocks; (4) inlet and outlet basesof the mill bases are horizontally aligned by using the equal height blocks; (5) the adjacent mill bases are horizontally aligned by using the equal height blocks; (6) the parallelism of the outlet bases of adjacent mills is aligned by using the equal height blocks; and (7) the frame parallelism of the adjacent mills is adjusted by using the equal height blocks. Compared with a traditional tandemmill board and a base adjusting method thereof, the adjusting method uses the equal height blocks for auxiliary measurement, so that a mounting reference surface can effectively extend precisely, andthe equipment mounting progress is accelerated when the detecting precision is improved.

Description

technical field [0001] The invention relates to the installation field of a multi-stand rolling mill, in particular to an adjustment method for a continuous rolling mill archway and its base. Background technique [0002] During the adjustment process of the rolling mill base and archway of the continuous rolling mill, the upper surface of the rolling mill base is not completely flat and high-precision processed surface. The installation position of the rolling mill frame is usually the finished surface, and the other positions are non-processed surfaces and form a certain platform convex. directly affects the erection of the ruler. In the process of aligning the parallelism of adjacent rolling mill bases, in order to improve the adjustment accuracy of the rolling mill base, the side of the rolling mill base is usually used as the detection reference point. How to detect the distance between two parallel vertical surfaces requires extending the detection surface. The traditi...
