China quality refractory Cordierite kiln shelf 500*450*15mm for fire ceramics
1. Introduction
Cordierite ceramics are well known for their low thermal expansion
and refractory character. Although cordierite is available as a
powder, when we use the term we are generally talking about ceramic
that went into the kiln as ordinary composite of ceramic powders
but emerges as a cordierite crystalline matrix (grown by the firing
process tuned to its needs).
Cordierite makes the ceramic manufacture of products like catalytic
converters possible. They constantly heat up and cool down quickly
and must not crack because of the shock. These converters get their
thermal shock resistance properties from a bonded matrix of
low-expansion cordierite crystals. These crystals form during
firing between 1300 to 1400C (interestingly, cordierite crystals
have a lesser thermal expansion along one axis than another). Thus,
the better the density of the precursor mix and controlled the
firing the better the properties of the cordierite material are.
Extruded kiln shelf
Extruded kiln shelf have holes running the length of the cross
section and are manufactured using high pressure vacuum extrusion.
They are used mainly in the sanitary ware and glass panel
industries.
2. Characteristics:
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
Plain kiln shelf
Plain kiln shelf are the most common type of primary kiln
furniture, usually produced by semi-dry pressing, but can also be
made by pressure-casting. There are extra large kiln shelf , extra
kiln shelf, plain kiln shelf, perforated kiln shelf, grooved kiln
shelf,trapezoid kiln shelf, round kiln shelf and special kiln
shelf.
