Abstract

The invention discloses a corrosion-resistant cement clinker warehouse top conveyor. A processing method for steel in the corrosion-resistant cement clinker warehouse top conveyor comprises the steps that (1) high-manganese steel, zinc oxide, chromic oxide, nickel sulfate, graphite, asbestos, chalcocite, stibnite and cassiterite are molten at the temperature of 1390-1450 DEG C so as to obtain molten mixture; and (2) silicon carbide, magnesium borate whiskers, graphene and the molten mixture are reheated at the temperature of 1550-1620 DEG C, and then water quenching is conducted at the temperature of 1240-1310 DEG C so as to obtain the steel in the corrosion-resistant cement clinker warehouse top conveyor. The corrosion-resistant cement clinker warehouse top conveyor has excellent mechanical strength and corrosion resistance.

Description

technical field [0001] The invention relates to a conveyor, in particular to a corrosion-resistant cement clinker roof conveyor. Background technique [0002] Conveyors have a long history. The ancient Chinese high-drum carts and water-lifting dump trucks are the prototypes of modern bucket elevators and scraper conveyors. A conveyor is a material handling machine that continuously conveys materials on a certain route, also known as a continuous conveyor. The conveyor can carry out horizontal and inclined conveying, and can also form a space conveying line, and the conveying line is generally fixed. The conveyor has a large conveying capacity, a long transportation distance, and can complete several process operations at the same time during the conveying process, so it is widely used. Among them, the cement clinker warehouse top conveyor is a conveyor specially used for conveying cement clinker. [0003] Due to the strong corrosiveness of cement clinker, the top conveyor...
