How to effectively identify the quality of Fire brick:

Look ahead to see the proportion of impurities in Fire brick. Generally speaking, there will

be impurities in the process of sintering Fire brick in strict accordance with the proportion

of ingredients, which is no problem. However, some manufacturers often do not produce

according to the proportion of materials used, so that sintered Fire brick have no hard

structure, which makes the quality of sintered bricks not up to standard, and then cheat

consumers with high prices.

When you buy Fire brick, you can check it through its surface. Generally, the surface of Fire

brick with high impurity content will be very rough, while the overall color of those Fire brick

with standard quality is uniform and the surface is smooth and flat, which can be visually

identified from the surface.

The second is the Fire brick sintering experiment, which is effective. Generally, when we buy

Fire brick, we will take samples for testing in advance. Especially before we decide to buy, we

must let the manufacturer conduct a high temperature test to check whether the sintering index

of Fire brick is the same as the standard index. As long as the experimental results do not deviate

significantly, then the quality of the brick body is still satisfactory, which is also a good method. If

you have any doubts about the previous method, you can use the second method for testing.
