High Alumina Universal Arc Firebrick is mainly used as steel drum lining.
Performance Characters:
High refractoriness, non- deformation, smooth appearance, good chipping resistance, non-stripping and strong abilities to resist corruption. Exact dimension and variety.
Advantages:
- A long service life, which is 210% longer than many other clay clinkers.
- The reduction of unit consumption can indicate the corresponding reduction of non-metallic inclusions in molten steel.
- The erosion resistance of slag and molten steel is strong, which can be seen from the section of high alumina brick after using
- Construction is convenient, because universal arc firebrick has radian on both ends, it can adjust radian through move when building, brick seam can achieve 1 millimeter commonly.
- The vertical seam of universal arc firebrick is small, which is 70% smaller than standard firebrick, so that correcting the erosion effect of molten iron layer moving up and down and penetrating the seam of brick.
Application:
Blast furnace, Electric furnace, hot blast stove, thermal boiler, glass kiln, cement rotary kiln, fertilizer gasifier and casting steel brick.
Standard size:
There are many different sizes of universal arc firebrick, welcome to customize by drawing!
