Embodiment Construction

[0010] In order to further describe the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] As shown in the figure, an online repair method and tooling for worn rolls of a ring rolling mill, including an online repair method and tooling for worn main rolls and an online repair method and tooling for worn cone rolls, is characterized in that: the wear The online repair method and tooling of the main roller are based on the fact that the wear of the main roller 2 is mainly the wear of the cylindrical surface of the main roller 2. As long as the worn surface is processed, the online repair of the main roller 2 can be realized, and the main roller 2 itself can be used. Rotational movement is the cutting speed, and the linear movement of the core roller frame 1 is the cutting depth. At the same time, designing suitable fixtures and controlling the feed speed can complete the processing of th...

Abstract

The invention discloses an online repairing method and tool for a ring rolling mill abrasion roller. The online repairing method and tool includes an online repairing method and tool for an abrasion master roller and an online repairing method and tool for an abrasion conical roller and is characterized in that the online repairing method and tool for the abrasion master roller machines an abrasion surface according to abrasion of a master roller, mainly abrasion of a cylindrical surface of the master roller, so that online repairing of the master roller can be achieved; the online repairing method and tool for the abrasion conical roller designs a proper tool fixture, and online repairing of upper and lower conical rollers can be achieved according to the condition that roller surfaces of the upper and lower conical rollers are conical and contact surfaces of the upper and lower conical rollers contacting with a rolled product are straight lines parallel to frame ground. The online repairing method and tool for the master roller and the upper and lower conical rollers includes the operation steps: designing one set of tools, and mounting cutters on the tools and then on core rollers. The online repairing method and tool has the advantages that online repairing of an abrasion rolling roller of a ring rolling mill can be achieved, and the operating rate of the ring rolling mill is increased.

Description

technical field [0001] The invention relates to the technical field of on-line repairing of worn rolls of a ring rolling mill, in particular to an on-line repairing method and tooling for worn rolls of a ring rolling mill, which are used for on-line repairing of worn rolls of a ring rolling mill. Background technique [0002] For ring rolling mills, after long-term work, the rolling rolls will wear to varying degrees, and the worn rolling rolls have a great impact on the quality of rolled products, especially the main roll and upper and lower cone rolls. At present, the main roll and the upper and lower cone rolls of the ring rolling mill are replaced at home and abroad, and the processing time is about 8 hours, which seriously affects the continuous production. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, to provide an online repair method and tooling for worn rolls of ring rolling mills, to re...
