Refractory arc brick is a semicircle, and the other end is a groove. No matter how thick it is, it will be flexible. Because refractory arc brick has no axis and has a slight deviation in size, it can also be built into a circle. So it is called universal arc. This kind of refractory arc brick is used in ladle.
Refractory arc brick is mainly used as the lining of steel ladle. It used to be mainly fire clay brick, but now it is gradually replaced by high alumina bricks. The high alumina universal arc brick is a kind of aluminum silicate refractory with alumina content more than 48%.
Refractory arc brick is mainly used as steel ladle lining.
Performance Characters of Refractory Arc Brick
High refractoriness, non- deformation, smooth appearance, good chipping resistance, non-stripping and strong abilities to resist corruption. Exact dimension and variety.
Advantages of Refractory Arc Brick
1. Long service life, 210% longer than refractory clay brick.
2. The reduction of unit consumption can indicate the corresponding reduction of non-metallic inclusions in molten steel.
3. Slag and molten steel have strong corrosion resistance, which can be seen from the section of high alumina brick after use.
4. The construction is convenient, because there are radians at both ends of the general arc-shaped fire-resistant brick. During construction, the radians can be adjusted by moving, and the brick joints can generally reach 1mm.
5. The vertical joint of the general refractory arc brick is small, 70% smaller than the standard refractory brick, to correct the erosion effect of the molten iron layer moving up and down and penetrating the brick joint.
Application of Refractory Arc Brick
Blast furnace, cement rotary kiln, thermal boiler, glass kiln, Electric furnace, hot blast stove, fertilizer gasifier and casting steel brick.
Standard size of Refractory Arc Brick
There are many different sizes of high alumina refractory arc brick, welcome to customize by drawing!
