Blast furnace bottom refractory brick masonry process

The masonry of blast furnace bottom refractory bricks is an important link in the construction of blast furnaces. The following is a detailed introduction to the refractory brick masonry at the bottom of the blast furnace:

1. Determine the construction plan and design requirements:

According to blast furnace specifications and design requirements, determine the size, shape and required refractory materials of the furnace bottom.

Prepare relevant construction drawings and technical documents, and ensure that construction personnel know and understand design requirements.

2. Preparation work:

Purchase high-quality refractory bricks and related auxiliary materials, such as refractory glue, mortar, etc.

Clean and level the construction area to ensure that the foundation surface is clean and firm.

3. Infrastructure construction:

Build a layer of concrete foundation or refractory brick base on the blast furnace foundation to support the furnace bottom refractory bricks.

A cushion is set on the foundation, and refractory glue or refractory mortar is usually used to bond the refractory bricks at the bottom of the furnace to the base to increase the stability and durability of the structure.

4. Masonry furnace bottom refractory bricks:

According to the construction drawings and design requirements, the furnace bottom refractory bricks are built layer by layer according to specific masonry methods.

Use refractory glue or refractory mortar to bond the refractory bricks at the bottom of the furnace together to ensure the stability of the overall structure.

During the masonry process, tools such as a level and a ruler are used to adjust the refractory bricks at the bottom of the furnace to ensure the flatness and verticality between the bricks.

5. Brick seam treatment:

After the furnace bottom refractory bricks are built, the gaps between bricks should be treated.

Use refractory glue or refractory mortar to fill the brick joints to increase the compactness and fire resistance of the overall structure.

6. Curing and maintenance:

After the furnace bottom refractory bricks are built, they are cured and cured. According to the requirements of refractory materials, control the appropriate curing time and temperature to improve the strength and refractory performance of bricks.

7. Inspection and maintenance:

After the furnace bottom refractory brick masonry is completed, a final inspection and test is carried out to ensure that the quality of the masonry meets the requirements.

During the use of the blast furnace, regularly check and maintain the refractory bricks at the bottom of the furnace, and repair and replace damaged bricks in time.

It should be noted that the masonry of blast furnace bottom refractory bricks is a complex work, involving technical requirements and safe operation. In actual construction, relevant design specifications and construction requirements should be strictly followed, and appropriate protective measures should be taken to ensure the safety of construction personnel and the stability of the furnace bottom.
