1. Sintered Steps Of Zircon Brick
Zircon brick is produced by sintered method which contains three steps, they are encastage,
kiln-firing and kiln-out.
Encastage
The method of encastage has a great influence on operation of kiln and the quality of zircon
brick, it can directly influence the heat transfer rate of zircon brick, combustion space and
uniformity of air distribution, at the same time, it is related to the time and fuel consumption.
The principle of encastage is that the stack should be stable and fire way should be
reasonable distribution which can make the air flow achieve uniform heating according to the
distribution of brick load.
Kiln-firing
As to intermittent kiln, burning should through three stages of heating-up, heat preservation
and cooling. However, continuous kiln only need to maintain the temperature of the kiln and
the system of the cart. During the process of firing, in order to guarantee the firing
temperature and the burning atmosphere, we should pay attention to the pressure system in
the kiln. Besides, in order to ensure the uniformity and stability of the quality of zircon brick,
we should try to eliminate or reduce the temperature difference in the kiln.
Kiln-out
The process of getting out the zircon brick from the kiln or unloading the zircon brick from the
kiln car is called kiln-out, during operation, to avoid the damage of refractory brick, refractory
bricks should be handed with care, and different types and varieties of refractory bricks
should be strictly separated.
