What Do You Know About Alumina Wear-resistant Ceramic Lining Board?

1. Alumina ceramic tiles composition: The main component is AL2O3.

2, type: according to the percentage of AL2O3 content, it is divided into 95 porcelain, 96 porcelain, 97 porcelain, 98 porcelain and so on.

3, Rockwell hardness HRA≥88. Hardness is second only to diamond, far more than wear resistant steel and stainless steel wear resistance. Wear resistance is equivalent to 266 times of manganese steel and 171.5 times of high chromium cast iron.

4, in the coal preparation industry use: mainly used in chute, cyclone, centrifuge and other ultra wear-resistant occasions.

5, density value: density value 3.6g/cm3, only half of steel, can greatly reduce the load of equipment.

6, thickness specifications: 4mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 30mm and so on. The shape is square, strip, trapezoid, circular arc and so on. Can paste plane, circular arc surface, conical surface and so on. 7, appearance requirements: in addition to the AL2O3 content, the appearance requirements of wear-resistant ceramic lining surface smooth, no black spots, smooth not rough, uniform color, in addition to vulcanization, side corners straight, easy to butt. 8. Aliases: high aluminum lining, wear-resistant ceramic lining, ceramic tiles, alumina tiles, pipe lining, ceramic lining, ceramic Mosaic wear-resistant ceramic lining common square and hexagonal,

9 wear-resistant ceramic tiles use: thermal power, iron and steel, smelting, machinery, coal, mining, chemical, cement, port terminal and other enterprises of coal, feeding system, pulverizing system, ash removal, dust removal system and all wear large mechanical equipment wear-resistant materials

10 wear-resistant ceramic lining features: a. Wear-resistant ceramic lining has high hardness, its Rockwell hardness is HRA80-90, the hardness is second only to diamond, far more than the wear-resistant steel and stainless steel. B. Wear-resistant ceramic lining has excellent wear-resistant performance. Its wear resistance is equivalent to 266 times of manganese steel and 171.5 times of high chromium cast iron. According to our more than ten years of customer tracking investigation, under the same working condition, the service life of the equipment can be extended at least ten times. C Wear-resistant ceramic lining is light in weight, its density is 3.6g/cm3, only half of steel, which can greatly reduce the load of equipment. D. The wear-resistant ceramic liner is firmly bonded and has good heat resistance. The wear-resistant ceramic liner is stuck on the inner wall of the equipment with heat resistant strong adhesive. It can run for a long time without aging at 350℃.

11. Identification method of wear-resistant ceramic lining plate

A. Favorable wear-resistant ceramic tiles has smooth surface, no black spots, smooth and not rough, and uniform color. In addition to vulcanization, wear-resistant ceramic lining will be pasted on A background paper for convenient construction, and the joint is continuous into A straight line

B. Density measurement, alumina content can be calculated by density measurement

C. Wear test, sand blasting machine at pressure 4.0kg/cm3, distance 50mm, injection Angle 45 degrees, time in 60 minutes to measure wear.
