High Alumina Arc Bricks are used in common circular industrial kiln linings, such as molten iron ladles, steel drums, and molten iron transfer ladles. The used circular furnace linings range from 10 to 200 tons.
The reason why arc bricks are called arcs is because they have arcs of different sizes. When building circles with different diameters, the arcs can be adjusted according to the inner and outer diameters or the number of bricks used. Arc refractory bricks have curvature at both ends, and the curvature can be adjusted by moving during masonry.
1. Arc bricks are available in different kiln diameters
There are 9 types of High Alumina arc bricks in the standard sizes C19-C27, and 16 types with different thicknesses. However, according to the sizes of different kiln diameters, we can design more suitable thicknesses for production. Under normal circumstances, they are basically used in the standard brick sizes. .
How many curved bricks are needed to build a circle with a diameter of 1 meter? This is calculated based on the number and suitability of the bricks. The calculation method can also be based on actual calculations or described in the drawings. Because it is cylindrical, the bricks are laid in gray. The joints are not large, so refractory mud can be added appropriately during masonry to increase the fullness of the mortar joint filling.
2. Material types of arc bricks
The material types of arc bricks are divided into high alumina, clay, corundum, aluminum silicon carbide, low porosity clay bricks and other materials. If you are building a circle with a larger diameter, you should first find the manufacturer to draw a brick shape of appropriate size, and then Carry out production and processing to ensure that the circles made of curved bricks can fit tightly, which saves effort and time during construction. Climbing bricks should also be designed to make the upper and lower linings more tightly fit.
3. Advantages of arc bricks
The advantage of High Alumina Arc Brick is that the vertical brick seams are smaller, which corrects the corrosion effect of the molten iron layer or the steel drum moving up and down and penetrating into the brick seams. However, when laying bricks, attention must be paid to the brick seams in the upper and lower layers to avoid double seams.
