Abstract
The utility model discloses a working roll on-line repair grinding device, which mainly comprises a repair grinding belt and a repair grinding tension setting device. The two ends of the repair grinding belt are drawn and fixed, and a preloaded spring is provided in the tension setting device which is fixed and arranged on the position where the preloaded spring is in the same drawing direction with the repair grinding belt. After the improvement, the working roll surface can be directly repaired and grinded without the roll release operation, and the labor intensity during the repairing and the grinding can be greatly reduced and the time for drawing roller, grinding roller and the roller group reverse loading can be greatly saved, and the effective operation of the unit of the repair grinding belt can be set by the tension setting device, to ensure the on-line repair grinding quality and eliminate the waste and oxide scales, thus to increase the smoothness of the roller surface.
Description
Technical field
The utility model relates to the online arrangement for grinding of working roll, specifically, relates to the online arrangement for grinding of the working roll that has the tension force setting device.
Background technology
Steel industry at home and abroad, the purpose of hot rolling finishing procedure is according to customer requirements, and the band steel is carried out the shearing of length and width; Simultaneously, the defective of belt steel surface is cleared up and end surface shape and profile are corrected, final production goes out to satisfy the steel plate of customer requirements.In the finishing production process, be extensive use of dissimilar roll levellers.The iron scale of, plucking aging owing to roll surface and surface of steel plate at high temperature very easily adheres to reasons such as roll surface, all may influence the quality of surface of steel plate.
For guaranteeing the surface quality of steel plate, produce high-quality product, generally all adopt both at home and abroad straightener integral body is pulled out, carry out the way of off-line reconditioning.This off-line reconditioning has following characteristics: what 1) straightener working roll reconditioning instrument adopted is manual reconditioning head.When roll marks appears in the surface of steel plate that adheres to working roll roll surface or aligning when the foreign material such as iron scale of surface of steel plate, because straightener roll gap adjustable range smaller (maximum roll gap 30mm), operating personnel can't directly carry out reconditioning to roll surface, can only notify mechanical personnel to carry out the roll release operation, with manual reconditioning head roll surface is carried out reconditioning behind the off-line, again straightener roller group is returned dress after reconditioning is finished.What 2) the straightener working roll reconditioning of prior art was adopted is the single-point reconditioning.By the roll release operation, adopt manual reconditioning head successively the work roll surface of defective to be carried out the single-point reconditioning behind the off-line again.
Though above-mentioned grinding method can guarantee the quality of steel plate, also caused following problem: 1) reconditioning overlong time; The straightener working roll reconditioning of prior art is adopted is off-line reconditioning behind the withdrawing roll, causes long being inevitable of reconditioning time.2) labour intensity is excessive; During the straightener working roll reconditioning of prior art, its withdrawing roll and reconditioning all are manually to carry out, and not only influence the printed line operating rate, and labour intensity are big.3) operation poor continuity; When roll marks was slight, the reconditioning inconvenience of straightener working roll or the withdrawing roll reconditioning of prior art were untimely, will inevitably make roll marks increase the weight of and caused the production poor continuity of production line.Therefore, the practical straightener working roll reconditioning instrument of design is the task of top priority.
Summary of the invention
The purpose of this utility model is, provides a kind of working roll online arrangement for grinding, with overcome work on hand roller arrangement for grinding reconditioning overlong time, labour intensity is excessive and the technical problem of operation poor continuity.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
The online arrangement for grinding of a kind of working roll mainly is made up of reconditioning band and reconditioning belt tension setting device; Described reconditioning band two ends stretch fixing, are provided with preloading spring in the described tension force setting device, and the tension force setting device is installed in its preloading spring draw direction and states on the reconditioning band draw direction consistent location.
Described reconditioning band mainly is made up of spring steel plate, intermediate connecting layer and outer field rubber layer, the felt layers of internal layer.
Described reconditioning belt tension setting device is provided with the tension force display.
Described reconditioning band two ends respectively are separately fixed on the support by a coupling bar, and described tension force setting device is 2, and symmetry is installed in the above-mentioned coupling bar two ends of any.
Deficiency at finishing production board production line working roll reconditioning existence, we design the online arrangement for grinding of aforesaid brand-new working roll, by the straightener top roll is depressed, the means of utilizing single roller to regulate, lift two lower rolls of pairing defective roller, the crawl smoothing roll makes the friction fully repeatedly of defective roller and reconditioning band, work roll surface is directly carried out reconditioning, need not both direct reconditioning working roll roll surfaces of roll release operation, thereby labour intensity alleviates significantly when making reconditioning, save a large amount of withdrawing rolls, grinding roller and roller group are returned ETL estimated time of loading, significantly improve unit effective operation rate.And can realize the tension force setting of reconditioning band by the tension force setting device, online grinding quality is effectively guaranteed, in time remove the foreign material and the iron scale of roll surface, improve the fineness of roller surfaces.Because what the online reconditioning adjusting device of the straightener working roll of the utility model technology adopted is the reconditioning band, can also carry out the while reconditioning to a plurality of blemish surfaces, no matter be top working roll or bottom working roll, promptly can adopt a plurality of reconditioning bands to realize multiple spot reconditioning simultaneously in case of necessity simultaneously, as long as increase the quantity of online reconditioning band and the rubber aspect is faced toward defect point.
