Kiln Building Refractory Bricks and Insulating Firebrick for Furnace Building and Repair.
Soft bricks and hard bricks are made of refractory fire clay, ground-up pre-fired
clay aka grog, and alumina .
Refractory fire bricks are fired to a very a high temperature in massive industrial furnaces.
The soft bricks are very light and porous and are designed to
insulate.
These are used in electric and gas fired kilns and as an outer
insulation in wood and salt kilns.
The dense / hard bricks are very heavy and are designed as structural
bricks and are employed in kilns and furnaces that have caustic or abrasive environments such as in wood burning kilns, salt kilns and coal fired
furnaces.
Refractory
shapes include precast cement and fused or sintered refractory products
that are formed prior to installation in furnaces, boilers or other
high temperature equipment. Refractories
are hard, heat resistant materials and products such as alumina,
silicon carbide, fire clay, bricks, precast shapes, cement or
monolithics and ceramic kiln furniture. Ceramics and refractories have
high melting points are suitable for applications requiring wear
resistance, high temperature strength, electrical or thermal insulation
or other specialized characteristics.
Kiln building refractory fire bricks, blocks, and tiles are stacked to form insulating furnaces, boilers or other thermal process vessel walls. The refractory fire bricks are usually cemented together with refractory mortar.
Please note:
REFRACTORY FIRE BRICKS SHIPPED UPS GROUND CARRY A $0.50 /BRICK PACKING FEE AND A $3.00 MINIMUM PACKING FEE.
-
Bricks carry a
$0.50 per brick double box safe packing fee when going UPS.
-
There is a $3.00 minimum on this packing fee.
-
ie. 1-6 bricks carry a flat $3.00 packing fee. Add $0.50 per brick for 7+ bricks.
-
NOTE: This does not
apply to large quantities of bricks which ship palletized via our
truck or common carrier.
