一种大跨度建张带钢表面打磨方法

By setting grinding areas in the middle and at the edges of the long-span tensioned steel strip, and using a grinding method that combines inclined straight lines and circular trajectories, the problem of uneven grinding and missed grinding caused by self-weight sagging is solved, achieving uniform and full-coverage grinding effect, which is suitable for various production lines.

AI Technical Summary

Technical Problem

During the grinding process, the large-span tension strips sag due to their own weight, resulting in uneven grinding and missed grinding issues, which are difficult to effectively solve with existing technologies.

Method used

By setting the grinding area range of the middle and edge of the strip, and using a combination of straight grinding at an inclination angle θ and upward circular trajectory stepping, the grinding force and speed are adjusted to ensure the maximum contact area and uniformity between the grinding head and the strip surface.

Benefits of technology

It achieves full coverage and uniform grinding of the strip steel surface, ensuring that defects are effectively ground out, meeting post-grinding quality inspection requirements, and is suitable for production lines of strip steel of different specifications.

Abstract

本发明公开了一种大跨度建张带钢表面打磨方法,包括:S1、根据现场带钢生产工艺参数,包括带钢宽度、厚度、两端张力,以获取带钢的悬垂量;S2、根据带钢的悬垂量,设定带钢的中部打磨区域范围及边部打磨区域范围;S3、根据不同分区进行设定打磨轨迹及打磨参数,并进行打磨。采用与带钢宽度方向呈倾斜角θ进行直线打磨,能够满足打磨均匀性要求,打磨头与带钢表面的接触要做到在打磨全过程中二者的接触面积达到最大化,在打磨过程中带钢表面全程的打磨磨痕方向保持一致;在边部打磨区域,采用向上行圆弧的打磨轨迹步进,可减轻边部直线打磨磨痕过重对磨后成像的影响。
