Refractory high temperature Cordierite kiln tray for fire ceramic
tiles
1. Product Description
Cordierite mullite material has excellent thermal shock resistance,
good strength and can be formed by pressing, extruding, casting and
vibrating into complex shapes. Cordierite mullite kiln furniture is
widely used in porcelain, heavy clay, glass panel, powder
metallurgy, magnetic materials, green energy, food, glass,
abrasives, iron and steel, mining and aerospace engineering.
Besides its use as kiln furniture, it is also extensively used in
kiln structures and kiln car system, where it is combined with
ceramic fiber to achieve the aims of improving fuel efficiency and
avoiding contamination.
The advanced processing equipment and the production craft coupled
with excellent inspecting instrument and strict production craft
have ensured the good quality of our product. Meanwhile, the
unceasing technical investment and the talented specialized
technically personnel have been keeping the manufacturing
technology always in the lead.
Small cordierite parts can be dry powder pressed. Large cordierite
pieces are formed by slip casting.
Slip casting is a process where the ceramic material is mixed with
water and poured into a
plaster mold. After a few hours the plaster draws off the water
from the mix and the sagger or
other shape can be released from the mold. Parts are then dried and
fired.
2. Advantages
Excellent energy savings
Lighter weight and higher load capacity
Excellent distortion resistance at high temperature
Suitable for faster firings with better bearing capacity for hot
and cold extremes
