1. Look at the proportion of impurities in refractory bricks. Generally speaking, in the process of sintering refractory bricks in strict accordance with the proportion of ingredients, there will be impurities, there is no perfect product, does not affect the quality of the product. However, some manufacturers often do not produce according to the proportion of materials, so that the sintered refractory bricks do not have a hard structure, so that the quality of the sintered bricks is not up to standard, and finally shoddy and high prices are used to cheat consumers. Then when you buy refractory bricks, you can check them through their surfaces.

2, is the refractory brick sintering experiment, this method is the most effective. Generally, when we buy refractory bricks, we will take samples for testing in advance. Especially before we decide to buy, we must let the manufacturer carry out high temperature test to check whether the sintering index of refractory bricks is the same as the standard index. As long as the deviation of the experimental results is not large, the quality of the brick body is still good, which is also a good method.

3, the use of weighing method. Refractory bricks have their own specifications size and volume density, you can calculate the weight of a single block. Because of the different aluminum content and production process, the single weight of refractory bricks is different. After receiving the goods, the buyer can randomly select several pieces for weighing, measure the weight and record it, and then bake the samples in a high temperature environment for a period of time to check the weight and see if the weight has changed.
