Fireproofing high density refractory brick fire clay brick for cement/ steel/ aluminum industry

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.

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 widely used.


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.
