What problems should be paid attention to when building refractory bricks?
Apr 25,2024
As the main refractory material in the construction industry, refractory bricks have many advantages, such as wear resistance, thermal conductivity, high density, good killing, and strong compressive and seismic resistance. In masonry, it must not only pay attention to the beauty of the appearance, but also pay attention to it. Let us introduce you to the issues that should be paid attention to when building.

1, dislocation: that is, the unevenness between the layer and the block;
2. Tilt: that is, uneven in the horizontal direction;
3. Uneven mortar joints: the width of the mortar joints varies, which can be adjusted by appropriately selecting the refractory bricks;
4. Climbing: the surface of the round wall has regular roughness, which should be controlled within 1mm;
5. Separation: In the curved masonry, the brick ring and the shell are not concentric;
6. Re-splicing: that is, the upper and lower mortar joints are superimposed, and only one mortar joint is allowed between the two layers;
7. Through joints: the mortar joints of the inner and outer horizontal layers of the refractory bricks are combined together, or even the metal shell is exposed, which is not allowed;
8. Open your mouth: The mortar joints in the curved masonry are small and large.
9. Hollow: That is to say, the mortar is not filled between the layers, between the bricks and the shell, and it is not allowed to be used in the lining of fixed equipment;
10, hairy joints: brick joints are not hooked, the walls are not clean;
11, snake: that is, longitudinal seams, circular seams or horizontal seams are not straight but wavy;
12. Masonry bulge: This is caused by the deformation of the equipment. During the masonry process, the relevant surface of the equipment should be smooth. When double lining refractory bricks are used, the insulation layer can be used for leveling;
13. Mud mixing: the wrong use of mud is not allowed.

Why refractory bricks can be refractory
Refractory brick is an inorganic non-metallic material with a refractoriness of not less than 1580 ℃. It is the basic material for high-temperature technology, the structural material for thermal equipment such as masonry kilns, and the functional material for manufacturing some high-temperature containers and components or for special functions. The successful use of refractory bricks under high temperature must have good organizational structure, thermal properties, mechanical properties and performance, that is, high refractoriness, load softening temperature, thermal shock resistance and chemical erosion resistance, in order to withstand various physical and chemical changes, to meet the requirements of thermal equipment and components.

Properties and abrasion resistance of refractory bricks
When making refractory bricks, one or more liquids need to be stirred together to make them highly fluid. Refractory bricks are made of a mixture of powder particles composed of various aggregates or aggregates and one or more binders, resulting in inconsistent properties of their own.
