1. The proportion of impurities in refractory bricks. Generally speaking, impurities will be generated during the sintering process of refractory bricks strictly according to the proportion of ingredients, which does not affect product quality, because there is no perfect product. However, some manufacturers usually do not produce according to the proportion of materials used, resulting in sintered refractory bricks without a hard structure, resulting in poor quality of sintered bricks, and finally deceive consumers with high prices. When you buy refractory bricks, you can check them through their surfaces.

2. The refractory brick sintering experiment, which is the most effective identification method. Generally, when we buy refractory bricks, we will take samples in advance for testing. Especially before we decide to purchase, we must have the manufacturer conduct a high-temperature test to verify whether the sintering index of the refractory bricks is the same as the standard index. As long as the test results do not deviate significantly, then the quality of the brick body is still satisfactory, which is also a good method.
3. Weighing method. Refractory bricks have their own size and volume density, from which the unit weight can be calculated. The aluminum content and production process are different, so is the unit weight. After receiving the goods, the purchaser can randomly select a few pieces for weighing, measure and record the weight, and then bake the samples in a high-temperature environment for a period of time to test the weight and see if there is any change.
