Abstract
The invention relates to a method for repairing the breakage on the surface of a polyurethane rubber roller for cold rolling, in particular to a method for repairing the breakage on the surface of the polyurethane rubber roller for cold rolling an acid continues rolling set, a withdrawing and straightening set, a re-coiling set, belonging to the technical field of maintaining metallurgical equipment. The technical scheme of method comprises the following steps of: stirring AB glue and polyurethane powder in a mixing way; repairing the surface of a broken roller on line; and polishing after repairing. The method has the benefit effects of being reasonable in technology and convenient in operation, being capable of repairing the polyurethane-packed rubber roller with the broken surface on line, being high in the repeated use ratio of the polyurethane-packed rubber roller, abundantly using the waste high polyurethane-packed rubber roller, reducing the cost and the improving the benefit.
Description
Affiliated technical field:
The present invention relates to a kind of method for repairing breakage on surface of polyurethane rubber roller for cold rolling, repair behind the polyurethane rubber covered roll surface fracture especially for cold rolling acid connection milling train group, withdrawal straightening stands, the use of rewinding unit, belong to metallurgical equipment maintenance technology field.
Background technology:
In metallurgical production, the polyurethane rubber covered roll that cold rolling acid connection milling train group, withdrawal straightening stands, rewinding unit use generally uses as carrying roller, higher by the probability of band steel scuffing in process of production, the rate of wear is fast, and the life-span is low, in case after damaging, influence strip surface quality.At present, the processing method that people use always is to roll off the production line to change, damage roller roll off the production line repair time long, expense is higher.
Summary of the invention:
The object of the invention provides a kind of method for repairing breakage on surface of polyurethane rubber roller for cold rolling, can onlinely repair, and improves polyurethane rubber covered roll repeat usage, reduces cost, and solves the problems referred to above that exist in the background technology.
Technical scheme of the present invention is:
A kind of method for repairing breakage on surface of polyurethane rubber roller for cold rolling comprises following steps: 1. damaged roll surface is repaired, the replacing that do not need to roll off the production line is repaired on line; 2. gather powder at waste and old polyurethane rubber roll roll surface, standby, it is standby to prepare AB glue; 3. damaged rubber roll surface finish is seen new stubble, then AB glue and polyurethane glue powder mixing stirring, stirring back mixture chemical reaction can occur and form congee shape thing, begin after 2 minutes to solidify, be applied in when mixture reaches semisolid and wait to repair the roll surface breakage, piling height is higher than more than the roll surface 2mm; 4. smeared the position in 6-8 minute and solidify, repair intensity after 30 minutes and reach more than 50%, polish processing then, until consistent with roll surface; 5. just can come into operation after 60 minutes, repair the position after 24 hours and reach final strength.
Mix 1:1 to 1:1.5 proportion proportioning by weight percentage between said AB glue and the polyurethane glue powder, promptly 1 part of AB glue of polyurethane glue powder is 1 part to 1.5 parts.Can adopt the range estimation operation, best ratio is an AB glue 50%, polyurethane glue powder 50%.
Said AB glue is exactly normally used acrylic acid modified epoxy glue or epoxy glue; The A component is acrylic acid modified epoxy or epoxy resin, or contains catalyst and other auxiliary agents, and the B component is modified amine or other curing agents, or contains catalyst and other auxiliary agents, mixes by description of product proportioning.
The invention has the beneficial effects as follows: technology of the present invention is reasonable, easy to operate, can repair by online polyurethane rubber covered roll to damaged surfaces, and high polyurethane rubber covered roll repeat usage makes full use of waste and old high polyurethane rubber covered roll, reduces cost, and increases benefit.
The specific embodiment
The invention will be further described by the following examples.
In an embodiment, a kind of method for repairing breakage on surface of polyurethane rubber roller for cold rolling comprises following steps: 1. damaged roll surface is repaired, repaired on line; 2. be ready to the polyurethane glue powder, gather powder at waste and old polyurethane rubber roll roll surface, adopt the sawing on roll surface of sawing mode, the powder collection under will saw is then deposited among the container standby, and preparation AB glue is standby; 3. during field repair, damaged rubber roll surface finish is seen new stubble, then AB glue and polyurethane glue powder mixing stirring, stirring the back mixture chemical reaction can occur and form congee shape thing and begin after 2 minutes to solidify, be applied in when mixture reaches semisolid and wait to repair the roll surface breakage, piling height is higher than roll surface 2mm; 4. smeared the position in 6-8 minute and solidify, repairing intensity reached 50% in 30 minutes, polished processing with file, angle grinding machine, emery cloth then, until consistent with roll surface; 5. 60 minutes back parts can come into operation, and repair the position after 24 hours and reach final strength (150kg/cm
2), can under-40 ° of C-120 ° of C environment, use.Mixed proportion is an AB glue 50% between AB glue and the polyurethane glue powder, polyurethane glue powder 50%; What AB glue was selected for use is WD-1001 high performance structures AB glue (liquid instrument glue), product standard number: Q/TECA 10-08.Meet all can selecting for use of standard production producer, the AB glue that embodiment selects for use Condar chemical plant, Shanghai to produce carries out proportioning by the description of product.
Claims (3)
