Heavy refractory brick is a high-density, high-strength refractory material, which is often used in the lining of high-temperature industrial equipment and furnace construction. The following is a detailed introduction to the construction process of heavy refractory bricks:

1. Preparation:

Check design drawings and specifications: ensure construction meets design requirements and relevant specifications.

Determine the construction plan and process: determine the construction plan according to the design requirements and specific conditions, and formulate the corresponding process flow.

2. Material preparation:

Heavy refractory bricks: Choose heavy refractory bricks that meet engineering requirements, and cut or arrange sizes as required.

Refractory mortar (optional): Select appropriate refractory mortar as the binder according to the needs.

3. Surface treatment:

Clean the surface: Make sure the construction surface is clean and dust-free, and remove dust, oil and other debris.

Apply refractory paint (optional): If necessary, paint a layer of refractory paint on the construction surface to improve fire resistance and chemical erosion resistance.

4. Masonry process:

Arrangement of bricks: According to the design requirements and construction plan, arrange heavy refractory bricks on the construction surface, and use refractory mortar to fix the bricks in the correct position.

Build brick walls or linings: Build brick walls or linings layer by layer according to the predetermined drawings and size requirements, and ensure that there are proper gaps between bricks and between bricks and the base.

5. Brick seam treatment:

Filling the brick joints: After the brick laying is completed, use refractory mortar or other caulking materials to fill the brick joints between the bricks to ensure a tight connection between the bricks.

6. Surface finishing:

Scrape the brick surface: After the brick masonry is completed, use scrapers and other tools to smooth the brick surface to ensure that the surface flatness meets the requirements.

7. Curing and drying:

Curing time: According to the requirements of refractory mortar, give enough curing time so that bricks and caulking materials can be firmly bonded.

Drying process: After curing, the newly built heavy refractory bricks are gradually heated and dried to ensure that the interior and joints of the bricks are fully dry.

8. Inspection and acceptance:

Check the construction quality: carry out visual inspection on the heavy refractory bricks under construction to ensure that they meet the design requirements and relevant standards.

Acceptance record: record the key parameters of construction, inspection results and acceptance opinions, and provide reference for subsequent operation and maintenance.

The above is the basic construction process of heavy refractory bricks. It is worth noting that the specific construction process may vary due to different projects and actual conditions. During the construction process, safety operating procedures must be strictly followed, and according to the design requirements
