Arc bricks are used in common circular industrial furnace linings, such as ladles, steel drums, and iron transfer ladles, with tonnages ranging from 10 to 200 tons.
Arc refractory bricks are called arcs because they have different sizes of arcs. When laying circles of different diameters, the arcs or the number of bricks used for laying can be adjusted according to the size of the inner and outer diameters. Arc refractory bricks have arcs at both ends, and the arcs can be adjusted by moving during laying.
02. Arc bricks have different kiln diameter sizes
There are 9 types of arc fire bricks in standard sizes C19-C27, and 16 types with different thicknesses, but there are also more suitable thicknesses designed to fit the sizes of different kiln diameters. In general, they are basically used in the size of standard bricks. How many arc firebricks are needed to build a circle with a diameter of 1 meter? This is calculated based on the number of bricks used and the degree of suitability. The calculation method can also be verified based on actual calculations or described in drawings. Because it is cylindrical, the masonry mortar joints are not large, so when building, refractory mud can be appropriately added to increase the filling fullness of the mortar joints.
03. Types of arc bricks
The types of materials of arc refractory bricks are divided into high alumina, clay, corundum, aluminum silicon carbide, low-porosity clay bricks and other materials. If you want to build a circle with a larger diameter, you should first find a manufacturer to draw a brick shape of the appropriate size, and then carry out production and processing to ensure that the circle built with arc fire bricks can fit tightly, which saves effort and time during masonry. In addition, climbing bricks should be designed to make the lining fit more tightly from top to bottom.
04. Advantages of arc bricks
The advantage of arc fire bricks is that the vertical brick joints are small, which corrects the erosion of the molten iron layer or steel ladle moving up and down and penetrating into the brick joints. However, when building, you must pay attention to the brick joints of the upper and lower layers, and no double joints should occur.
