Alumina ceramic is a ceramic material with more than 95% AL2O3 as the main raw material and corundum (α-AL2O3) as the main crystal phase. It has high mechanical strength, high hardness, high high temperature insulation resistance, chemical resistance and thermal conductivity. Good and other excellent comprehensive technical performance, high density, low wear, impact resistance product performance characteristics, smooth surface and convenient construction, mainly used in coal, coal preparation, steel, mining, thermal power plants and other industries equipment wear-resistant lining, especially suitable for In the coal preparation plant, the heavy medium coal conveying pipeline, the conveying channel of the mine and the wharf, the discharge port of the spiral pipeline of the blanking chute and the dust equipment are more worn.
Alumina-lined ceramic wear-resistant pipe fittings are widely used in developed countries in Europe and America. After the imported coal preparation technology entered my country in the 1980s, it has gradually occupied a dominant position in my country in recent years, and is currently the product with the longest wear-resistant life.
1. Unique attachment technology
At present, domestic manufacturers use traditional strip and mosaic ceramic sheets. After long-term operation, the glue gradually loses its original chemical properties, and the ceramic sheets will fall off in a large area immediately, which seriously affects the normal operation of production. In view of domestic ceramic shedding, after years of practical experience, our company has developed and developed "three insurances": the introduction of the advanced technology of British Morocco Hi-Tech, the use of arch principle design, and tailor-made according to the size of various pipe diameters. Buckle groove type self-locking curved ceramic sheets of various radians ensure no gap between the ceramic and the pipe wall. It completely solved the problem of ceramic falling off and filled the domestic blank. Currently applying for the National Spark Program project.
The ceramic piece forms a 360-degree mechanical self-supporting structure (it will not fall off without glue). The ceramic piece is close to the inner wall of the steel pipe. The flakes will not fall off. The gap between the ceramic piece and the inner wall of the steel pipe is filled with special adhesive glue that is wear-resistant and heat-resistant, which plays a double protection. Make sure that the ceramic piece does not fall off permanently.
