Default Application Of Refractories In Different Parts Of Glass Furnaces

Refractories are the main building materials for glass furnaces. It has a
decisive impact on the quality of glass, energy consumption and the cost. The
development of glass melting technology mainly depends on the development and
quality of refractories.

Sidewall and bottom of melter predominately consist of fused cast AZS block,
whereas sintered zirconia mullite brick in some cases can be applied to bottom
area, where the application condition is not that demanding. Beneath the fused
cast AZS lie the chamotte block at the very bottom, in between AZS ramming mix
is filled. In corner area fused cast AZS with Void Free Casting is used
exclusively. Fused cast AZS is so far the primary refractory brick for glass
furnace.

In tin bath, alumina forming brick such as sillimanite and bottom block are
used typically.

Silica brick is used also quite frequently in glass furnace. It finds its
application for melter crown, front wall, breast wall and gable as well. It is
the traditional choice for the crown.

α-β Fused cast alumina block is used extensively for breast wall, as well as
sidewall and bottom of cooling zone. Fused cast α-βalumina block and Fused
cast βalumina block are also used in the crown and superstructure.

Direct-bonded magnesia chrome brick is most suitable for upper checker, where
strong alkali corrosion exist, or lower and middle checker, where sodium
sulfate condenses. There are several substitute brick of chrome magnesia for
checker chamber, among them are magnesia zirconia brick, magnesia forsterite
brick and magnesia alumina brick. While the first two have similar thermal
properties and usage as magnesia chrome brick, magnesia alumina brick is
usually used for the middle checker of small regenerator. Light weight
magnesia forsterite brick is used for the insulation layer of checker chamber.
Sillimanite brick can be used also for checker in low temperature area (below
800°C). In principle the refractory material used for wall is in line with
that of checker brick at the same height.

Sunrise is a refractory material supplier from China. The main products of
Sunrise include fused cast AZS block, fused cast alumina block, mullite brick,
zircon brick, alumina bubble brick, sillimanite brick, corundum brick, low
porosity fireclay brick, high alumina brick, all kinds of glass furnace
ramming masses, etc..
