1. Sintered Molding Method To Manufacture Zircon Brick
Sintering is the process of compacting and forming a solid mass of material by pressure and heat
without melting it to the point of liquefaction. Sintered molding method as a general method is widely
used in glass industry, zircon brick is manufactured by this method.
There are four main stages in producing sintered zircon brick: powdering, molding and compacting,
drying, and sintering.
1.Powdering: Turning the raw material of zircon brick into powder. Grinding, atomization, chemical
reaction, and centrifugal disintegration are four ways of producing material powder.
2. Molding and compacting: The powder of zircon brick is transferred into a mold press. Zircon brick
with intricate shapes and details can be manufactured more efficiently with this method because the
particles conform to the mold better. The mold is then pressurized and compacted. Heat is added to
fuse the particles. In some cases, the sintered zircon brick may be re-pressed to reduce porosity.
Hand-molding produces zircon brick of low strength and low density. Mechanical-molding produces
zircon brick of high strength and high density
3. Drying: The zircon brick that have been formed need to be dried before sintering so that the cracks
can be avoided in the sintering process due to moisture content in the zircon brick.
4. Sintering: It is done at a high temperature kilns which is as high as or higher than their use
temperature.
Unlike casting technology where refractory is melted into a more or less liquid state before being
shaped, sintered method to produce zircon brick is forged while still in a powdered form. By not
having to be melted, several phases are eliminated from the conventional process. This reduces
manufacturing time of zircon brick, which can be crucial for high volume production. What is more, a
relatively low temperature is needed to sinter zircon brick.
