Roll gap measuring tool

Abstract

A roll gap measuring tool includes multiple groove depth measuring templates and at least one template support rod detachably connected to the groove depth measuring templates. The template bodies of the multiple groove depth measuring templates have unequal widths, and the width of each template body corresponds to a groove depth of a roll group. Since the groove depth of the roll group is positively correlated with the roll gap, the change in the measured groove depth of the template body can represent the roll gap measurement result. Therefore, when the rolling mill is not running, the roll gap measuring tool can be used to measure the groove depth to confirm whether the roll gap of the roll group is within acceptable limits, and also to determine the wear condition of the roll group.

Claims

1. A roll gap measuring tool, comprising: Multiple groove depth measuring templates, each of the multiple groove depth measuring templates including a template body and a connecting part disposed at one end of the template body, the widths of the template bodies of the multiple groove depth measuring templates are not equal, and the width of each template body corresponds to a groove depth of a roll group; and at least one template support rod, the template support rod being detachably connected to the connecting part of the groove depth measuring template.

2. The roll gap measuring tool as described in claim 1, wherein, The connecting part of the continuous rolling groove depth measuring template forms a threaded rod, the template support rod is a hollow rod, and one or both ends of the template support rod form a screw hole, the template support rod can be screwed to the connecting part.

3. The roll gap measuring tool as described in claim 1, wherein, The connecting part of the continuous rolling groove depth measuring template has a screw hole, and one or both ends of the template support rod form a threaded section, and the template support rod can be screwed to the connecting part.

4. The roll gap measuring tool as described in claim 1, wherein, Each of the groove depth measuring templates has a template identification mark on its surface.

5. The roll gap measuring tool as described in claim 4, wherein, The template identification mark includes information about the rolling mill corresponding to the template body.

6. The roll gap measuring tool as described in claim 4, wherein, The template identification mark includes information on the groove depth corresponding to the template body.

7. The roll gap measuring tool as described in claim 4, wherein, The template identification mark includes information about a rolling mill station and information about the depth of a rolling groove corresponding to the template body.

8. The roll gap measuring tool as described in any one of claims 1 to 7, wherein, The template body is a rectangular plate. The length of the template body of each groove depth measuring template is equal, but the width of each groove depth measuring template is different. The four corners of the rectangular template body are rounded.
