Connection method for axial play measuring device for horizontal roll of edging mill

Abstract

The invention discloses a connection method for an axial play measuring device for a horizontal roll of an edging mill. The connection method includes mounting the measuring device (30) to a mill housing (20) of the edging mill through a connector (10). By the connection method in the technical scheme, the contact measuring device can be mounted onto the mill housing of the edging mill, so that the axial displacement of the horizontal roll relative to the mill housing can be measured accurately and accurate reference data can be provided for the subsequent regulating operation.

Description

technical field [0001] The invention relates to the measurement of the axial movement of the horizontal roll of the edger, in particular to a connection method for the measuring device of the axial movement of the horizontal roll of the edger. Background technique [0002] During the steel rolling process, the force on both sides of the horizontal roll of the edge mill is uneven. Due to the gap between the assembly gap or the wear of the parts, the horizontal roll may be axially deformed under the action of the lateral rolling force. move. In order to facilitate the adjustment of horizontal rolls or to provide accurate parameters for eliminating the mill gap, it is necessary to measure the axial movement of the rolling mill with a measuring device. Due to the very compact structure of the edger and the small space around the rolls, there are high requirements for the connection and fixing of the measuring device. Among other things, the measuring devices can be contact and...

Problems solved by technology

Since the measuring device is fixed outside the rolling mill archway, the distance between the measuring tool and the roll is too far, so a long measuring rod is required, which requires the measuring rod to have good rigidity, that is, the cross-sectional area and volume of the measuring rod need to be increased , and then increase the self-weight of the measuring tool

Since the self-weight of the measuring tool may affect the measurement accuracy, and the measured displacement may be caused by the displacement of the rolling mill arch and the displacement of the roll, this arrangement is likely to lead to inaccurate measurement
