Problems solved by technology

The bimetal composite pipe designed with this structure makes it difficult to control the quenching process. When the quenching hardness is high in production, cracks will occur during use, and blocks will easily occur, resulting in product scrapping; when the quenching hardness is low, the service life will be greatly reduced. At the same time, after quenching The length and size of the inner tube is not easy to control, resulting in secondary cutting
In order to avoid the problem of cracks in the inner tube, the cracks are mostly controlled by increasing the wall thickness of the inner tube, which increases the cost while increasing the weight

Abstract

The invention provides a bimetal compound wear-proof cover. The bimetal compound wear-proof cover comprises an inner layer and an outer layer, wherein the inner layer is made of high-chromium cast iron, the outer layer is made from a No.20 steel plate, the inner layer and the outer layer are in interference fit, and the inner layer and the outer layer are matched in size. The bimetal compound wear-proof cover has good compressive property, strong abrasion resistance and strong corrosion resistant performance.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a bimetal composite wear-resistant sleeve. Background technique [0002] The existing bimetallic composite pipe consists of two layers: the outer pipe is a carbon steel pipe, which mainly bears external force or internal pressure; surplus cooperation. The bimetal composite pipe designed with this structure makes it difficult to control the quenching process. When the quenching hardness is high in production, cracks will occur during use, and blocks will easily occur, resulting in product scrapping; when the quenching hardness is low, the service life will be greatly reduced. At the same time, after quenching The length and size of the inner tube are not easy to control, resulting in secondary blanking. In order to avoid the problem of cracks in the inner tube, the cracks are mostly controlled by increasing the wall thickness of the inner tube, which increases the ...
