Ladrillos refractarios de arco alto de alúmina

The arc of the universal arc brick is a semicircle, and the other end is a groove. No matter how thick it is, it will be flexible and maneuverable. Because it has no axis, even if the size is slightly deviated, it can still be laid into a circle. So it is called arch refractory bricks, and this brick is used in ladles.
Universal arc high alumina refractory bricks are mainly used as linings for steel ladles. In the past, they were mainly clay, but now they are gradually being replaced by high-alumina bricks. High alumina arch refractory bricks are a kind of aluminum silicate refractory material with an alumina content of more than 48%. It is formed and calcined by bauxite or other raw materials with a high alumina content. It has high thermal stability and a refractoriness of more than 1770℃. It has good slag resistance.

Advantages of arch refractory bricks

Small brick joints: Brick joints can generally reach 1 mm, and its vertical brick joints are smaller, and the straight joints are reduced by 70% compared with standard bricks, which effectively improves the airtightness and stability of the circular structure.
Strong adjustability: It can adapt to circular or curved structures, and the roundness can be adjusted as needed. Even if there is a slight deviation in the size, it can be built into a circle;
Increase capacity: For cylindrical devices, the universal arc can reduce the number of straight joints, effectively increase the overall capacity, and make the brick joints tighter;
Convenient construction: For masonry circles, the universal arc is more convenient than right-angle bricks, which can reduce labor and improve masonry efficiency;

Masonry method of high alumina arch refractory bricks

The construction method of universal arc bricks is usually to climb the slope, build one ring after another, like a step, not layer by layer. When laying, it is usually necessary to use starting bricks to adjust the steel drums of different diameters to ensure the flatness and roundness of the masonry.
