Super abrasion-resistant extruding and drying roller

Abstract

The invention discloses a super abrasion-resistant extruding and drying roller. The super abrasion-resistant extruding and drying roller comprises an extruding and drying roller iron core, a buna-n rubber layer and a polyurethane rubber layer, wherein the buna-n rubber layer is arranged between the extruding and drying roller iron core and the polyurethane rubber layer; the inner side surface of the buna-n rubber layer is adhered to the outer side surface of the extruding and drying roller iron core; the outer side surface of the buna-n rubber layer is adhered to the inner side surface of the polyurethane rubber layer; the thickness of the polyurethane rubber layer is 1 / 3 of the thickness of the buna-n rubber layer. The super abrasion-resistant extruding and drying roller adopts a two-layer composite rubber layer; the abrasion resistance of the polyurethane rubber layer of the surface is high (the abrasion resistance is 3-4 times higher than that of the surface of the existing extruding and drying roller); the abrasion resistance of the surface of the extruding and drying roller can be improved; the super abrasion-resistant extruding and drying roller is capable of preventing the roller surface from shedding and staying on the surface of the strip steel due to abrasion; the problem that the foreign matters are pressed into the surface of the extruding and drying roller can be avoided.

Description

technical field [0001] The invention relates to a squeezing roller, in particular to a super wear-resistant squeezing roller. Background technique [0002] With the rapid development of the automobile industry, alloyed hot-dip galvanized steel sheets have been more and more used in automobiles due to their excellent corrosion resistance, coating performance and welding performance. Especially in light of automobile lightweight requirements, alloyed hot-dip galvanized automobile sheets are constantly developing towards high-strength steel. [0003] As an alloyed automobile steel plate production line, it is necessary to carry out leveling treatment on the strip steel after alloying. The leveling machine adopts wet leveling and is equipped with a high-pressure water gun. In this way, there are a lot of water marks on the surface of the strip steel after leveling, which must be squeezed dry. The roller squeezes out the water marks on the surface of the strip, otherwise the wat...
