Kiln Furniture Cordierite Mullite Hollow Batts

Kiln Furniture Cordierite Mullite Hollow Batts 

Cordierite-Mullite kiln furniture is composed of cordierite, mullite and glass phase. Due to the high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite kiln furniture formed good property of excellent thermal shock resistance. Cordierite-Mullite kiln furniture can be used at 1350℃, which makes it can fulfill the production demands of most ceramic industry.

Extruded batts have holes running the length of the cross section and are manufactured using high pressure vacuum extrusion, before being cut and surface-ground to guarantee the highest standard of flatness and dimensional accuracy. They are used mainly in the sanitaryware and glass panel industries, but can be found in a number of applications including the biscuit and glost firing of tableware.

Compared with plain batts, extruded batts have several advantages:
A. Weight reduction of approximately 35% - 50%, whilst increasing the load capacity of the batt. For example, a 38mm-thick extruded batt has the same weight as a 23mm-thick pressed batt of the same size, but can bear 5 times the load.

B. Energy Savings. Tests have shown that using extruded batts in a shuttle kiln firing glass panels, fuel consumption can be reduced by between 30% and 70%.

C. Reduced bend at high temperatures. 1200mm long Beijing Trend extruded batts supported by silicon carbide beams have shown virtually no bend during use. This is extremely useful where flatness is critical, such as in the firing of glass panels.

D.Their ability to disperse heat is twice that of a solid batt of similar size, allowing them to bear extremes of hot and cold much better, thereby increasing their service life. This makes extruded batts especially suitable for faster firings.

Extruded batts can be split into eight sub-categories as follows: Thin Extruded Batt, Large Extruded Batt, Long Extruded Batt, Plain Extruded Batt, Perforated Extruded Batt, Cut-out Extruded Batt, Interlock Extruded Batt and Special Extruded Batt.

Thin Extruded Batt: Thickness under 25mm

Large Extruded Batt: Width over 590mm

Long Extruded Batt: Length over 1200mm

Plain Extruded Batt: Thickness ≥25mm, Width ≤590mm, Length ≤1200mm

Perforated Extruded Batt: Holes drilled into one or both faces of the batt

Cut-out Extruded Batt: Cut-out from the side of the batt to accommodate props, or large hole cut from the centre for use as a wash-basin / vanity-basin support.

Interlock Extruded Batt: Batts with a shiplap along one or both lengths to allow them to interlock in use.

Special Extruded Batt: Any extruded batt with special features not listed above.
