What are the appearance defect indicators of refractory bricks

Refractory bricks are refractory materials made from fire-resistant clay or other refractory materials. It is mainly used for building smelting furnaces, and can withstand high temperatures of 1,580℃-1,770℃. Now more and more people are starting to pay attention to this kind of brick, mainly because it is needed in many occasions now, please follow the editor to understand it.

The produced refractory bricks are allowed to have deviations in size. The general deviations need to be controlled within the specified range, which can make our entire use easier and ensure safety. In addition, there are also some missing corners. Yes, there are corresponding standards to specify what it is. The appearance of karst caves is also common to us. Generally, many people now pay attention to this problem. As long as some karst caves appear within the specified range, it is understandable and tolerant. In addition, fire-resistant There will be some cracks in the bricks, and the specified defect indicators also exist in a certain range, so that we can use it more easily in the future.

Refractory bricks have slowly walked into our side, and played a very important role, worthy of our careful attention. It has a certain shape and size of refractory material. According to the preparation process, it can be divided into fired bricks, non-fired bricks, fused bricks (fused cast bricks), refractory and heat insulating bricks; according to the shape and size, it can be divided into standard bricks, ordinary bricks, and special bricks.
