Understanding the strong wear resistance of wear-resistant ceramic lining plates greatly reduces maintenance frequency, saves costs and labor, and increases market demand.

1. Measurement tolerance: Use a vernier caliper to measure the length, width, and height of the wear-resistant ceramic lining plate. Aluminum oxide ceramics have a certain shrinkage rate, so they all have a certain tolerance range.

2. Density measurement: The alumina content can be calculated by measuring the density. The density of ceramic lining plate is 3.6g/cm3, and the density of 95 ceramic lining plate is 3.65 g/cm3. The drainage method is applied for accurate density measurement.

3. Measurement of hardness: Hardness can be measured under experimental conditions and should be tested according to the method specified in GB/T16534.

4. Conduct a wear resistance test using a sandblasting machine under the conditions of a pressure of 4.0kg/cm3, a distance of 50mm, a spraying angle of 45 degrees, and a time of 60 minutes to measure wear. A good wear-resistant ceramic lining plate has a smooth surface without black spots, a smooth and rough color, and a white lining plate with a jade like texture.

5. The corundum sand on the surface of the wear-resistant ceramic lining plate should be polished off before packaging. The shape of the iron bowl of the lining pipe fittings is consistent with the inner hole of the lining plate, and the smaller weight is not less than 5g. The porcelain cap is consistent with the reserved hole, seamless, and flat. Black spots indicate impurities in the alumina raw powder that have not been effectively removed. Especially for ceramic liners with a thickness less than 10 millimeters, high stability requirements for kiln temperature are required. Excessive heating or uneven cooling and heating can cause deformation of the lining.
