Preparation work for refractory brick construction

The preparation work before refractory brick construction is crucial, affecting the quality of construction and subsequent service life. First, ensure that the surface of the base is clean and free of debris, and accurately check and fix all anchors and hooks. The template production and installation must meet the standards to ensure smooth construction. Before construction, it is also necessary to conduct trial mixing according to the designed mix ratio and make test blocks for inspection to ensure the matching of materials and equipment.

Batching and mixing of refractory bricks

Batching and mixing are crucial links in the construction of refractory bricks. Batching should be carried out strictly in accordance with the design standards. Clean water must be used when adding water, and the pH value of the water should be between 6-8. During the mixing process, a forced mixer must be used to stir to ensure the uniformity of the mixture and the construction quality. The amount of water added is generally controlled at 30%-38%, and the specific data needs to be adjusted according to the actual situation.

Construction process of refractory bricks

Refractory bricks need to be constructed in stages and steps. Each layer of bricks needs to be vibrated with a vibrator to expel the bubbles in the inner layer and ensure tight bonding. During the vibration process, it is necessary to insert and lift slowly to avoid forming holes. For bricks with a pouring thickness of less than 200mm, they should be poured in place at one time to ensure the overall tightness and firmness.

Maintenance method of refractory bricks

In order to ensure the construction quality and service life of refractory bricks, they must be maintained strictly in accordance with the maintenance requirements. The maintenance humidity must not be lower than 100%, and the maintenance temperature must be controlled between 10-35 degrees. Generally, demoulding can be done 36 hours after pouring, and the total maintenance time is 3-7 days. The specific time needs to be adjusted according to the actual construction environment.

Refractory brick baking process

After curing, the refractory bricks need to be baked to expel the internal moisture. The baking process can also preheat the kiln to prevent the kiln from cracking due to instantaneous temperature rise. Baking must be carried out strictly according to the baking curve to ensure the structural stability of the refractory bricks and the safety of the kiln.
