A kind of wear-resistant laminated bimetallic composite material and its manufacturing method

Abstract

The invention provides a preparing method of an abrasion-resisting lamination double-metal composite material. After raw material selecting, abrasion-resisting multiple-layer material bonding interface selecting, blanking raw material groove arranging, blanking, rolling, spheroidizing annealing and anti-oxidation dope coating, the abrasion-resisting lamination double-metal composite material is prepared. Carbon steel base material machining performance is achieved, and meanwhile abrasion resistance of abrasion-resisting materials is achieved. A pipe, a structure shape and the like machined and manufactured by an composite assembly have the machinability of a carbon steel structure pipe and the abrasion resistance, and meanwhile the abrasion-resisting multiple layers cannot be broken and fall off easily. Therefore, the novel composite material can replace a pure abrasion-resisting high manganese steel material in a special field to be used in various industries, the material is an energy-saving environment-protecting material and is more and more popular among people, and the application fields of pure high manganese steel and carbon steel are replaced gradually.

Description

technical field [0001] The invention relates to a wear-resistant laminated bimetal composite material and a manufacturing method thereof, belonging to the technical field of composite material production. Background technique [0002] Wear-resistant steel plates are widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, bricks and tiles and other industries because of their high wear resistance and good impact performance. Compared with other materials, they have high cost performance. It has been favored by more and more industries and manufacturers. At present, the commonly used wear-resistant steel plate is a plate made of an alloy wear-resistant layer with a certain thickness of high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. product. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates. ...

AI Technical Summary

Problems solved by technology

This kind of composite pipe has exposed a lot of problems during use, such as the slurry transported by the pipeline solidifies on the pipe wall during the transmission process, reducing the size of the pipe diameter and affecting the transmission flow

The solidified slurry is usually cleaned by physical methods-beating. During the cleaning process, the cladding layer is easily broken, and the broken cladding layer will fall off in one piece, which seriously affects the service performance and life of the pipe.

It takes a certain period of time to replace the pipeline, which increases the cost of manufacturing and maintenance, affects the reputation of the product and customers, and also affects the schedule of the user's engineering project, hindering the construction plan
