High-quality silicon brick manufacturers: common appearance problems of silicon bricks

Silica bricks are the basic materials for high temperature technology and the structural materials of thermal equipment such as masonry kilns, but we will also encounter some problems in production. Let's take a look at the common appearance problems of silica bricks today.

1. For raw or over-burning, the way of entering the kiln, the firing temperature and the holding time should be traced back.

2. Loose, raw material sintering quality, molded body quality, mud gradation, sintering system, etc., should be traced back.

3. If the dimensional tolerance is large, the performance of the raw material, the particle size distribution of the mud, the proportion of the model design, the model size, the kiln loading method and the firing system should be traced back.

4. The deformation should be traced back to the mud, the kiln loading method and the firing system. High-quality silicon brick

5. For cracking, the raw material treatment quality, batching ratio, mud moisture content, molding quality, drying quality and firing system should be traced back.

6. For peeling, track the particle size distribution, water content and molding quality of the mud.

7. For missing corners and missing edges, the quality, model and treatment of dry billets should be traced back.

8. For melting holes, trace the low melting point impurities of the raw materials, the purification quality of the raw materials, and the impurities mixed in the production process. High-quality silicon brick

9. The fire mole should be traced back to the charging method of the kiln and the thermal working conditions of the firing process.

High-quality silicon brick manufacturers: What are the technical requirements for silicon brick masonry construction?

We all know that the high temperature industry is a dangerous industry. In order to ensure safety, not only the quality of silicon bricks is required, but also the masonry technology of the construction personnel. The quality of masonry is closely related to the service life. Let's take a look at the technical requirements of silicon brick masonry construction today..

1. When laying silicon bricks, the starting point needs to be built from the low end of the industrial kiln to the high end or the hot end to the low end in sequence, and select appropriate silicon bricks for cleaning and marking at the operation point, and select silicon bricks of different materials according to different parts of the industrial kiln., select silicon bricks that meet the technical requirements of masonry, prepare corresponding refractory mud according to the silicon bricks during masonry, and leave expansion joints according to the construction requirements, the width of the expansion joints should not have negative tolerances, and there should be no sundries in the joints.

2. During the lining masonry process, the silicon brick joints are required to be kept within 2mm, and the mud in the joints must be full.

3. The upper and lower layers of lining masonry must be staggered and no gaps can be overlapped. High-quality silicon brick

4. When masonry, the brick joints should be straight, the wall should be dense, the gaps on the surface of the silicon brick should be filled with original slurry, and the excess refractory mud on the surface should be scraped off in time.

5. When masonry, hit the masonry wall with a wooden hammer or rubber hammer, and it is strictly forbidden to hit the silicon brick with a hammer or other object.

6. Avoid construction defects such as dislocation, lining inclination, uneven ash seams, heavy seams, masonry bulging, and mortar mixing.

7. Layered and segmented masonry, it is forbidden to mix mud and mortar, and masonry according to technical requirements when encountering holes.

8. When encountering anchors or metal parts during masonry, the masonry silicon bricks should seal the anchors or metal parts to avoid exposure to the air and affect the quality of masonry construction.
