refractory brick is a special high-temperature-resistant material, which has a wide range of uses, including being used as a lining or component in high-temperature environments such as kilns, heat treatment equipment, and industrial furnaces. The following is a detailed introduction of the materials and methods used in common masonry refractory bricks:
1. Brick material selection: According to the specific working conditions and requirements, select the appropriate refractory brick material. Common refractory brick materials include alumina refractory bricks, silicon carbide refractory bricks, high alumina refractory bricks, etc., and each material has its specific refractoriness and erosion resistance.
2. Brick type selection: choose the appropriate brick type according to the shape and size of the required masonry structure. Common brick types include straight bricks, corner bricks, trapezoidal bricks, semicircular bricks, etc., which can be combined and cut according to actual needs.
3. Masonry method: Masonry refractory bricks usually use refractory mortar (refractory slurry) as a binder. First adjust the refractory mortar to an appropriate consistency, and then use masonry tools (such as scraper, spatula) to apply it on the contact surface of the refractory bricks, and then lay the bricks on the required position in turn, and use a hammer Tap lightly to ensure a tight bond.
4. Masonry sequence: According to the design requirements and construction plan, the masonry shall be carried out in a certain order. In general, the bottom and surrounding foundation bricks are laid first, and then layer by layer upward. During the masonry process, attention should be paid to the treatment of brick joints, and refractory mortar is usually filled to improve the overall sealing and stability.
5. Curing and maintenance: After the masonry is completed, enough time should be given for curing and maintenance. Depending on the type and thickness of the refractory mastic, it may take longer to achieve optimum strength and stability.
In short, masonry refractory bricks need to choose the appropriate material and brick type, and adopt the correct masonry method and sequence. Reasonable masonry can ensure that refractory bricks have good high temperature resistance and stability, so as to meet the needs of industrial applications in high temperature environments.
