Description

Morgan Thermal Ceramics produces multi-grades ofinsulating firebricks with limiting temperatures of useranging from 1100°C to 1760°C. Each grade isformulated to meet specific thermal and physicalrequirements.

Morgan Thermal Ceramics Insulating Firebricks are

made from high-purity refractory clays, with graduatedadditions of alumina for the higher temperature products,and a carefully graded organic filler, which burns outduring manufacture to give a uniform, controlled porestructure.

Each brick is machined to precise tolerances on all sixfaces.

Type Insulating firebricks

Classification Temperatures From 1100°C up to 1760°C

Maximum Continuous Use Temperature The maximum continuous use temperature depends onthe application. In case of doubt, refer to your localMorgan Thermal Ceramics sales office or distributor foradvice.

Typical Applications Recommended for use as a primary hot face refractorylining or as back-up insulation behind other refractories infurnaces, kilns, flues, refining vessels and heaters,regenerators, gas producers and main, soaking pits,stress relieving furnaces, reactor chambers and similarhigh temperature industrial equipment.

Special Shapes In addition to the standard brick sizes, Morgan ThermalCeramics Insulating Firebricks are available in pre-machined special shapes. The blanks for very largeshapes are formed by mortaring together two or moreslabs, the unique large sizes of these slabs ensuring theleast number of sections and joints in the finished article.

A Morgan Thermal Ceramics distributor will be pleased toreview your requirements.

FeaturesLow thermal conductivity

Gives good thermal insulation, enabling the use of thin-

walled constructions.

Low heat storage Due to their light weight and low thermal conductivity,bricks absorb minimal heat inward, giving significantenergy savings in cyclically-operated kilns.

Purity The very low iron and alkali flux content confers goodrefractoriness and the high alumina content contributes totheir stability in reducing atmosphere.

High hot compressive strength

The accurate dimensions

Enable the bricks to be laid more quickly, with thin,uniform joints, allowing the construction of strong andstable structures.

Large brick or slabs They are available in sizes 230 x 610 x 64 or 76mm and250 x 640 x 64mm. These can be machined into specialshapes, incurring fewer sections and joints.

Purpose-designed packaging Protects the bricks in transit and facilitates on-sitehandling.
