What are the precautions for pre-masonry refractory bricks?

The pre-masonry of refractory brick is an important work in the furnace. What are the precautions during the pre-masonry of refractory brick?

First of all, we need to understand the purpose of pre-masonry, mainly including the following five points:

1. In the process of pre masonry, check whether the design of refractory brickis wrong;

2. Check whether the brick type meets the masonry requirements and the masonry effect;

3. It can be checked whether the size and tolerance of the refractory bricks are within the reasonable range and whether it will affect the masonry;

4. Determine the masonry form;

5. Understand the masonry key points in the masonry process, master the masonry key points and important parts;

By understanding the purpose of pre masonry, we can understand the process of masonry lining more clearly. Precautions for refractory bricks in the process of pre masonry are as follows:

1. First, the pre masonry site shall be flat and clean to avoid affecting the pre masonry effect;

2. The pre-masonry refractory brick masonry shall be built in strict accordance with the drawings and national standard pre-masonry standards;

3. The pre masonry work shall meet the requirements of formal masonry;

4. In the process of pre masonry, all quality indexes shall be strictly controlled to make full preparation for formal masonry;

5. The refractory bricks to be pre laid shall be printed with marks, and shall be laid according to the marks to avoid failure to complete the construction and masonry requirements during normal laying;

6. After the pre-masonry, the size and expansion of the masonry shall be recorded and inspected for the convenience of formal construction and masonry;

7. In the process of pre laying, the bricks shall be handled with care, removed and placed. The refractory bricks that do not conform to the size and are not within the tolerance range shall be treated in time to avoid affecting the normal masonry.

The work of pre masonry is simple, and it is closely related to the formal construction. The purpose of pre masonry is to check whether the refractory bricks meet the masonry requirements and standards, and to avoid design errors. The quality of masonry work is closely related to the normal operation of the kiln.
