Problems solved by technology

The squeeze roller is a key component in the emulsion removal solution, but during use, the emulsion entering the squeeze roller will cause bearing lubrication failure and damage the bearing, and the existing squeeze roller has insufficient surface hardness and poor wear resistance , poor drying effect
The above problems lead to the short life of the squeeze rollers, which require frequent maintenance and replacement during the rolling process, which restricts the production efficiency of the entire unit. Cost of production

Embodiment

[0039] figure 1 A schematic structural view of the wear-resistant squeezing roller according to this embodiment is shown.

[0040] Such as figure 1 As shown, the two ends of the roll body 2 made of rolled steel are sleeved on the central shaft 1 made of alloy steel through bearings 12 respectively, and the cushion layer is wrapped on the outer circumference of the roll body 2, including a fluorine rubber layer 3 and a polyurethane layer 4 , the fluororubber layer 3 is located between the roller body 2 and the polyurethane layer 4, the thickness of the fluororubber layer 3 is 4 mm, the thickness of the polyurethane layer 4 is 2 mm, and the sealing structure is arranged at both ends of the roller body 2 for sealing the roller body 2 Seals are formed between both ends of the roller body 2 and the central shaft 1, including a positioning sleeve 8, an end cover 6, a retaining ring 5 and a skeleton oil seal 7. The positioning sleeve 8 is set on the central shaft 1 outside the rolle...

Abstract

The invention discloses a wear-resistant wringing roller. The wear-resistant wringing roller comprises a central shaft, a roller body, a cushion layer and sealing structures, wherein the two ends of the roller body are correspondingly arranged on the central shaft through bearings in a sleeving mode, the cushion layer is wrapped around the outer circumference of the roller body, and the sealing structures are arranged at the two ends of the roller body and are used for forming seals between the two ends of the roller body and the central shaft and between the roller body and the central shaftcorrespondingly. According to the wear-resistant wringing roller, the situation that lubrication of the bearings is failed due to the fact that the emulsion enters the interior of the wringing rollercan be effectively prevented, the wear resistance and elasticity are both achieved, and the service life and the wringing effect are ensured.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and more specifically relates to a wear-resistant squeezing roller. Background technique [0002] In the production process of cold-rolled strip steel, due to the high speed of the rolling mill, it is necessary to use a large amount of emulsion. The emulsion will remain on the surface of the strip steel and affect the quality of the strip steel, and it is difficult to remove. Strip steel with a large amount of residual emulsion will produce burnt-like corrugated traces after annealing. The squeeze roller is a key component in the emulsion removal solution, but during use, the emulsion entering the squeeze roller will cause bearing lubrication failure and damage the bearing, and the existing squeeze roller has insufficient surface hardness and poor wear resistance , The squeezing effect is poor. The above problems lead to the short life of the squeeze rollers, which require frequent mainte...
