Blast furnace production from the roof into the iron ore, coke, slag with flux (limestone), feeding the small car played an important role as the main means of transportation, since most of the vehicle loading ore, coke has more sharp edges, sharp to furnace lining abrasion erosion is serious, at the same time, because of the large weight skip rope, reducer, such as load, failure occurs extremely easily, cause great economic losses.Therefore, to improve the service life of skip car, it is necessary to solve the problems of anti-erosion, anti-wear and self-weight of skip car lining board.After a number of companies comparison experiment, wear - resistant ceramic lining board use effect is very good.
Wear-resistant ceramic lining board with aluminum oxide as the main raw material, with rare metal oxide as flux, after 1700℃ high temperature melting and burning respectively with special rubber and high strength of organic adhesives combination, also can be used alone as the lining of wear-resistant ceramic lining board.The hardness of wear-resistant ceramic lining is large, rockwell hardness is 80-90, larger than the hardness of minerals such as ore, coal ash residue;Strong wear resistance, wear resistance is equivalent to the steel plate 266 times, the density is small and easy to process, and rubber vulcanization together can be cut, can be twisted assembly, not limited by the shape, size and installation site of the equipment.
Wear-resisting ceramic lining board only in accordance with the strict paste process for operation, to achieve the effect of ceramic pieces firm not to fall off, first with a sandblast gun, Angle machine or steel wire brush to clean up the surface to be glued, so that it shows a metallic luster, the more rough the surface more clean paste effect is better;Then clean the surface to be glued with alcohol to remove oil stains from the surface;Apply the adhesive evenly to the surface to be pasted, then paste the wear-resistant ceramic lining board one by one, and beat it with a rubber hammer to make it in close contact.
After the use of wear-resistant ceramic lining plate, the weight of the charging car of the blast furnace itself is reduced, which reduces the load of the main coil motor and reducer, and also reduces the wear of the steel wire rope and track, thus creating benefits from the steel wire rope and iron production profit.
The wear-resistant ceramic lining plate is used as the lining plate of the blast furnace hopper, which reduces the wear of the equipment, improves the reliability of the charging equipment and ensures the stable and high yield of the blast furnace.
Wear-resisting ceramic lining board of the use of specifications and sizes mainly ore size and impact force, temperature, etc., is not limited to the use of which type.
