1. Firstly, let's look at the type of refractory material, because when selecting refractory materials, we must choose those that comply with the specifications and standards we are using, so that we can use them more confidently.
2. When manufacturing refractory materials, it is important to understand the internal materials used in the kiln.
3. When firing refractory materials in the kiln, it is necessary to ensure that the hot air heater, air duct, and cover door of the kiln can operate normally. Otherwise, the produced refractory materials will not meet the specifications and the strength will be reduced.
4. After completion, the refractory materials need to be placed in a single cylinder cooling machine for further processing, and we will not find any swelling when selecting the refractory materials.
