Introduction of

Corundum mullite brick



The
corundum mullite brick products use imported tabular
corundum and high-purity fused corundum as the main
raw materials, and adopt advanced superfine powder
adding technology. After mixing, forming, drying, and
firing at high temperature in shuttle kiln. When the
corundum mullite brick is produced, a certain
thickness of thermal insulation material is designed
and produced on its non-working surface according to
the conditions of use.
Corundum mullite brick adopts
special production technology to combine two
different materials into a whole. Under the premise
of ensuring no fracture and keeping the thermal
expansion rate close to the same, the corundum
mullite brick has high temperature resistance,
corrosion resistance, The effect of high strength
and erosion resistance can effectively solve the
problem that double-layer masonry of thermal
insulation materials cannot be used in the lining
of the rotary kiln.

Advantage of corundum mullite brick

1. Corundum
mullite brick has the characteristics of high
refractoriness and good thermal shock stability 2, high
temperature strength, excellent corrosion resistance,
strong slag resistance 3. With the characteristics of small
expansion coefficient, low creep, and resistance to
spalling, corundum mullite bricks are suitable for the use
of high-temperature kilns under various
conditions
