DESCRIPTION (IFB23 1420°C)
Thermal Ceramics produces six grades of insulating firebricks with limiting temperatures of use range of 1420°C This grade is formulated to meet specific thermal and physical requirements. Insulated firebricks are made from high-purity refractory clays, with graduated additions of alumina for the higher temperature products, and a carefully graded organic filler, which burns out during manufacture to give a uniform, controlled pore structure. Each brick is machined to precise tolerances on all six faces.

Insulating firebricks
CLASSIFICATION TEMPERATURES Max 1420°
MAXIMUM CONTINUOUS USE TEMPERATURE
The maximum continuous use temperature depends on the application. In case of doubt, refer to the data sheet for advice.
· FEATURES
Low thermal conductivity - Gives good thermal insulation, enabling the use of thinwalled constructions.
· Low heat storage - Due to their light weight and low thermal conductivity, JM bricks absorb minimal heat, giving significant energy savings in cyclically-operated kilns.
· Purity - The very low iron and alkali flux content confers good refractoriness and the high alumina content contributes to their 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 and stable structures.
·· Purpose-designed packaging - Protects the bricks in transit (in cartons containing 4 to 25 item, depending on shape) and facilitates on-site handling.
TYPICAL APPLICATIONS
Recommended for use as a primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, electric kilns, flues, refining vessels and heaters, regenerators, gas producers and main, soaking pits, stress relieving furnaces, reactor chambers and similar high temperature industrial equipment.
SPECIAL SHAPES
These bricks are easily cut to shape with hand tools. The dust is dangerous so wear approriate eye and face masks.
NOTE
Insulation Fire Bricks (IFBs) are commonly used in electric and gas kilns where there is minimal abrasion against the lining of the kiln. This is due to the bricks being lightweight and not very dense.
They can be used in gas furnaces and kilns but will deteriorate much faster.
