Fire brick, also known as refractory brick, is the type of brick
used for fireplaces, kilns, and furnaces on the inside lining. This
is because they are strong insulators, which helps to make the
applications more energy-efficient with minimal heat loss.
Refractory fire brick is designed to stand up to extremely high
temperatures that other regular brick cannot.
|AL2O3 % (min)||35-38%||38-42%||50-55%||60-65%|
Refractoriness under load,
|Apparent porosity (%)||20-24||19-23||18-22||18-22|
|Bulk density (g/cm³)||2.05-2.1||2.1-2.15||2.15-2.25||2.25-2.35|
|Cold crushing strength (MPa)||≥30||≥35||≥45||≥50|
|Thermal expansion at 1000°C (%)||≤0.55||≤0.55||≤0.4||≤0.4|
Dense fire brick is most typically used in extreme chemical and
mechanical applications such as a furnace or a wood-fired kiln,
which are subject to higher temperatures and greater potential
damage. For less extreme applications, such as an electric kiln.
1.low thermal conductivity, good thermal insulation performance.
2.long service life, easy operation, could be shaped freely
3.Product specification: standard form, normal standard, shaped and
special shaped bricks.
4.Can be used in various kilns because of its cheapness and general
tray package. Among all of the refractory materials, it is the most
Laurel produce a comprehensive range of fire clay brick consisting
of 30-85% Alumina all of which exhibit excellent strength. For more
arduous environments we offer a hand fired “super duty” Fire clay
brick with a very high mechanical strength.
Typically our firebrick range is based upon flint clay giving it
both a low iron and low alkali characteristic. Resistance to
thermal shock, abrasion,chemical attack and reducing atmospheres
are just some of the key criteria determining choice of product
within each application. a wide range of sizes are held in stock.
Whether you’re considering fire brick for your fireplace, furnace,
or other high-temperature application, fire brick is a necessity
for safe and effective operation.
