    The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.

    Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.

    Description:


    Laurel produces a comprehensive range of Fire clay brick consisting of 30-55% 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.


    Features:


    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.
