Insulating Firebrick

Description Thermal Ceramics produce full grades of insulating firebricks with limiting temperature of use ranging from 1260°C to 1760°C. Each grade is formulated to meet specific thermal and physical requirements. JM and TJM firebricks are made from high-purity refractory clays, with graduated additions of alumina for higher temperature products, and carefully graded organic filler, which burns out during manufacture to give a uniform, controlled pore structure. Each brick is machined to precise tolerance on all six faces. Features l Low thermal conductitive Gives good thermal insulation, enable the use of thin-walled constructions. l Low heat storage Because of their light weight and low thermal conductivity, JM and TJM bricks absorb minimal heat, give significant energy saving in cyclically-operated kilns. l Purity The high alumina contents confer good refractoriness and very low iron and alkali fluxcontent contributes to their stability to reducing atmosphere. l High hot compressive strength l The accurate dimensions Enable the bricks to be laid more quickly, with thin, uniform joint, allowing the construction of strong and stable structures. l Large bricks or slabs. Are available in sizes 230×610×64 or 76mm and 25×640×64mm. These can be machined to special shapes, incurring fewer sections and joints. l Purpose-designed packaging (in carton containing 4-25 items, depending on shape) Protects the bricks in transit and facilitates on-site handling. Typical Applications l Recommended for use as 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 mains, soaking pits, stress relieving furnaces, reactor chambers and similar high temperature industrial equipment. Special shapes l In addition to the standard rick size, JM and TJM insulating firebricks are available in pre-machined special shapes. The blanks for very large shapes are formed by mortaring together two or more JM/TJM slabs, the unique large sizes of these slabs ensuring the least number of sections and joints in the finished article.
