Method and apparatus for producing hard particle abrasion resistant composite steel board

Abstract

The invention relates to a method and an apparatus for producing hard particle abrasion resistant composite steel board. The method includes puddle welding on the surface of the steel board base to form a welding puddle, where no slag is allowed to exist; uniformly sprinkling the hard particle material onto the welding puddle; rolling on the puddle with a roller thereafter, so as to roll the hard particle material into the welding puddle or surface layer of the welding puddle to form a hard particle composite layer which is flat in the surface. Therefore, the hard particle abrasion resistant composite steel board comprising the hard particle composite layer and the steel board base is formed. The invention has advantages that abrasion resistance performance can be evidently enhanced by deploying any materials in high hardness as the hard particle material of the composite layer, such as hard alloy, cermet, diamond or the like; the steel board has strong bonding strength, flat surface, uniform thickness, and the performance of the hard particle material is unlikely to change due to high temperature decomposition or burning loss. The apparatus is not only specialized in production of hard particle abrasion resistant composite steel board, but also suitable for production of composite steel board of other types, and an automatic production can be further implemented thereby.

Description

technical field [0001] The invention relates to a method and equipment for manufacturing hard-point wear-resistant composite steel plates, which are mainly used for producing composite steel plate products with ultra-high wear-resistant service life, and are also suitable for manufacturing other types of composite steel plates. Background technique [0002] Half of the steel in the machinery industry is used for the production of spare parts every year. Most of the spare parts fail due to low wear life, and 80% of the failure of mechanical parts is caused by wear. In the mining, metallurgy, cement, coal, electric power, petrochemical, transportation, machinery manufacturing and other industries, most of the production equipment in the process of use, due to the serious wear of the parts, the key parts or the entire production line cannot operate normally. , thus causing great economic losses to the enterprise. Improving the service life and safe operation of equipment wear ...
