Problems solved by technology

At the same time, due to the recycling of dust in the sinter, a large amount of K, Na, Pb, Zn and other harmful elements are enriched. These harmful elements intensify the corrosion of the metal baffle, and also cause the life of the baffle to decrease.

Abstract

The invention relates to a high-temperature energy-saving anticorrosive coating material for a sintering pallet metal baffle, and an application method thereof, wherein the coating material comprises,by weight, 15-35 parts of zirconite powder, 3-10 parts of silicon carbide powder, 39-43 parts of mullite powder, 3-10 parts of ball clay, 2-7 parts of spodumene, 2-5 parts of metal silicon and 5-15 parts of magnesium aluminum silicate gel powder. During the application, water is added to the coating material to prepare a fine slurry, the surface of a metal baffle is sprayed or coated with the fine slurry, and the coating is firmly attached to the surface of the metal baffle after drying and heat treatment so as to form a high-temperature-resistant energy-saving anti-corrosion ceramic coating.According to the invention, the coating material can reflect the heat of the material layer, reduce the temperature of the inner wall of the baffle, and protect the inner wall surface of the metal baffle from being corroded so as to prolong the service life of the baffle, achieve the energy-saving effect and easily reduce the production cost of sintered ore.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, in particular to the field of anti-corrosion coatings, and more specifically relates to a high-temperature energy-saving anti-corrosion coating for sintering trolley baffles. Background technique [0002] The most widely used sintering equipment in ironworks is the belt sintering machine, and the sintering machine trolley is composed of the trolley body, baffle plate, heat insulation pad, grate bars, wheels and so on. The baffle of the belt sintering machine trolley is one of the main wearing parts. The baffle is generally cast with ferritic ductile iron. Due to the harsh working conditions, it is easy to deform and crack when working under high temperature and severe cold and hot conditions, and the service life is generally shortened by 3 to 6 months. Therefore improving the service life of the baffle plate is one of the urgent problems to be solved in the production of the sinteri...
