Semi-direct bonded magnesia-chrome bricks
Semi-direct bonded magnesia-chrome bricks are made on
the base of
technology for common magnesia-chrome
bricks, by means of improved
technology and with
addition of some additives. With good corrosion
resistance and spalling resistance and easiness of kiln
coating, the
product is suitably used in burning zone of
dry method cement kilns
with capacity of under 1500t/d,
also for lybol kilns and wet method
cement kiln. They
are excellent substitution for common magnesia-chrome
bricks.

Magnesia bricks and forsterite bricks
Common magnesia brick
The common magnesia brick is made from sintered
dense magnesia clinkers,which is characterized
by highre fractoriness,good corrosion resistance and has
found wide applications in glass tank furnace,lime
kilns, non-ferrous furnaces,
hot metal mixer,alloy making furnace and electric furnaces and
so on.The magnesia brick with over 95% MgO
content is made using two-step sintered magnesia clinker or
fused magnesia clinker
as raw materials and
firing at high temperature. With high direct bonding rate and
goodcorrosion resistance, the brick has been
widely used in various high temperature
furnaces and kilns.
Forsterite brick
The forsterite brick is made using synthesized material
of olive and serpentine as raw materials and shaped under high
pressure and firing at high temperature. It has good corrosion
resistance
and high-temperature strength and has been used
in glass kiln regenerator successfully.
