Abstract

The invention discloses a preparation technology of a wear-resistant and high-hardness wear-resistant plate and a scraper conveyor comprising the wear-resistant plates. The scraper conveyor comprises two racks, a driving shaft is arranged between the two racks, bearing seats matched with the driving shaft are arranged in the racks, chain wheels are arranged in the middle of the outer surface of the driving shaft and located between the two racks, chains are arranged on the chain wheels, a plurality of scrapers are arranged on the chains, the wear-resisting plates are arranged on the scrapers, and one end of the driving shaft penetrates through one rack and is connected with the output end of a driving motor. The preparation technology and the scraper conveyor have the beneficial effects that high carbon content contributes to graphitization and promotes magnesium absorption, so that all or most of carbon is spherical graphite, and the wear-resistant effect of the wear-resistant plate is enhanced.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a preparation process of a wear-resistant and high-hardness wear-resistant plate and a scraper conveyor containing the wear-resistant plate. Background technique [0002] The conveyor that uses a scraper chain to transport bulk materials in the tank is called a scraper conveyor. KS Scraper Conveyor Scraper Conveyor The adjacent middle groove of the scraper conveyor can be bent to a limited extent in the horizontal and vertical planes, which is called a bendable scraper conveyor. Among them, the working face conveyor whose fuselage is bent at 90 degrees at the intersection of the working face and the transportation roadway is called "corner scraper conveyor". In the current coal mining face, the role of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine, so it has become an indispensable main equipment in ...
