Description

Technical Field

[0001] The utility model belongs to the technical field of refractory bricks, and in particular relates to a different-pore combined refractory brick. Background Art

[0002] During the preparation of the kiln, a movable brick needs to be retained as a fire viewing port. The refractory bricks at the fire viewing port need to be sealed, but not sealed. They should be sealed when the kiln is opened. When the temperature reaches a certain level, the refractory bricks at the fire viewing port can be moved away to observe whether the temperature meets the requirements. After the observation, the refractory bricks are immediately sealed. This process is repeated until the required sintering temperature or technical requirements are reached. The fire viewing port refractory bricks are designed to be movable. From the existing technology, it is difficult to observe the situation inside the kiln after the common refractory bricks are installed, and it is difficult to judge the subsequent operations. In addition, the refractory bricks lack safety measures. When the refractory bricks are opened for observation, there are safety hazards. For this reason, we have designed a combination of refractory bricks with different holes.
