Problems solved by technology

[0004] In view of the above situation, in order to solve the defects of the prior art, the object of the present invention is to provide a wear-resistant middle plate in the middle groove of a scraper conveyor with a low friction coefficient and its production method, which can effectively solve the problem of rapid wear of the existing middle plate and solve the problem of wear and tear. The problem is that the surface friction coefficient is greatly increased due to wear-resistant treatment, and the noise and motor power of the scraper conveyor are increased at the same time, and the working environment becomes more severe.

Abstract

The invention relates to a wear-resistant middle plate of a middle groove of a scraper conveyor with low friction coefficient and a production method of the wear-resistant middle plate, the problems that the existing middle plate wears fast and the surface friction coefficient is greatly increased due to wear-resistant treatment in order to solve the wear problem can be effectively solved, and meanwhile, the noise and motor power during the operation of the scraper conveyor are increased, and the working environment becomes more severe. The technical scheme to be solved is that the wear-resistant middle plate of the middle groove of the scraper conveyor with low friction coefficient comprises a middle plate main body, an alloy wear-resistant layer and a wear-resistant coating. The production method is simple, easy to operate and high in production efficiency, the prepared middle plate of the scraper conveyor not only has excellent wear-resistant performance of the alloy wear-resistantlayer, but also has excellent wear-resistant performance of the wear-resistant coating, which is an innovation of the middle plate of the scraper conveyor.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a wear-resistant middle plate of a middle groove of a scraper conveyor with a low friction coefficient and a production method thereof. Background technique [0002] China's proven coal reserves reached 724.116 billion tons, and the coal mining volume in 2017 exceeded 3.484 billion tons. Comprehensive mechanized coal mining technology (referred to as fully mechanized mining technology) is currently a mining technology commonly used by major coal industry groups. The scraper conveyor is the first link of coal shipment and the most important transportation device in the coal mining face. At present, the material of the middle plate of the scraper conveyor is mainly 16Mn steel plate. Although the steel plate has good weldability , but poor wear and corrosion resistance. During the coal mining process, the scraper and the chain are constantly rubbing against the midd...
