Fused casting rebounded AZS bricks and sintered zirconbricks
Fused casting rebounded AZS bricks
This brick is made by using fused cast AZS as starting
materials and sintered at high temperature. With highly
inertial property, the product does not react with other
materials except reaction with some basic refractory
materials, so, it is used in the area contacting with
silica bricks and other areas like peep hole, skew brick
and sub-bottom of the tank.

Sintered Zircon bricks
The bricks are featured with the good corrosion- and
thermal- resistance，and are used in the areas with less
chemical attacking and thermal-shaking like ports and
joints with regenerator.
