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
