IMPORTANT PLEASE READ - Due to a high workload of booked metal casting courses and sign commissions any orders placed during 7th to 20th of September inclusive will be on hold

You can still checkout, and we will process orders, dependent upon stock levels when we re-open on the next working day. Thank You!

Apologies for any inconvenience caused

DESCRIPTION (JM23 1260°C) 
(This is a 6" non standard width brick 16 per box delivery can be between 6 to 8 weeks due to ordering in from Italy- Must be ordered in multiples of 16 that is1 full Box price shown is per brick)

Thermal Ceramics produces six grades of insulating firebricks with limiting temperatures of use ranging from 1260°C to 1790°C. This grade is formulated to meet specific thermal and physical requirements. JM 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. Thermal Ceramics also produces a range of mortars to suit the different grades of brick.

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.

·         Large bricks or slabs - They are available in sizes 230 x 610 x 64 or 76mm and 250 x 640 x 64mm. These can be machined into special shapes,   incurring fewer sections and joints.

·         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, 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
In addition to the standard brick sizes, JM insulating firebricks are available in pre-machined special shapes.
We will be pleased to discuss your requirements
