High Quality Cement Rotary Kiln Wear Resistant Red Silicon Mullite
Brick For Cement Kiln
Silicon mullite brick by adopting high grade bauxite and SiC as raw
material and special sintering process, silica mullite bricks are
characterized by high strength, good performance of abrasion
resistance and thermal shock resistance, constant forming
protective layer for reducing accrection formation, long
application cycle etc. silicon mullite fire brick is mainly
designed for rotary kiln of cement industry, and silicon mullite
firebrick is used for the transition zone, calcining zone of medium
and small cement kiln.
Silicon Mullite Brick Description
Slilica mullite fire brick is mainly made of mullite as the main
material and contain over 30percent SiO2 content and over 60
percent Al2O3 content. slilica mullite firebrick refractoriness
generally is more than 1580 degree. silicate mullite fire brick is
composed mainly of mullite, corundum, SiC and glass. refractory
silicon mullite brick is formed at the junction of granules as
mullite, glass and SiC. silicate mullite firebrick with high
quality and various excellent properties for application in all
kinds of high temperature furnace and kilns, such as roasting
furnace.
Properties of Silicon Mullite Brick
.High temperature resistance,
.Erosion resistance,
.Wear resistance properties,
.Refiring small contraction,
.Excellent thermal shock resistance,
.Strong resistance to the corrosive gas and slag.
Manufacturing Process of Silicon Mullite Brick
Silicon mullite block is made with raw material high grade bauxite
and SiC and special sintering process. Silica mullite bricks are
characterized by high density, good performance of abrasion
resistance and thermal shock resistance. silicate mullite block can
constantly form protective layer for reducing accrection formation,
long application cycle.
Advantages of Silicon Mullite Brick
1.Good acid and erosion resistance, powerful anti high-temperature
strength.
2.Soften melting temperature is 1620~1670 °C.
3.Low thermal shock resistance.
4.Natural silica as raw material, plus regular mineralizer.
5.Ensure good bonding and structural strength of furnace.
6.Good heat resistance and long service life.
