JM’s insulating heat-resistant brick products are at the forefront of industries such as petrochemicals, metallurgy, ceramics and glassmaking, where performance is required in environments with classification temperatures up to 1650 \u00b0C.<\/p>\n

Each type is formulated to meet specific thermal and physical requirements and the bricks are precisely finished on all six surfaces.<\/p>\n

FEATURES<\/strong><\/h2>\n

– Low thermal conductivity
\n– Low heat storage
\n– High purity, consistently high quality raw materials
\n– Low iron and alkaline fluxes for high load resistance at high temperatures
\n– High compressive strength at high temperatures
\n– Precise dimensional tolerances
\n– Large blocks or slabs and special shapes available
\n– Specially designed packaging protects the bricks during transport and facilitates on-site handling<\/p>\n

AREAS OF APPLICATION<\/strong><\/h2>\n

– Aluminium anode furnaces, primary electrolytic cells, holding and melting furnaces, secondary melting furnaces
\n– Petrochemical industry: heaters, flues, refining vessels and reactor chambers
\n– Iron and steel industry: Hot air furnaces, hot air mains and distribution pipes, heat treatment and galvanising furnaces
\n– Metals industry: heat treatment and atmospheric furnaces
\n– Ceramics industry, including kilns for household and laboratory use
\n– Glass industry
\n– Direct contact (hot zone) and back-up insulation in industrial furnaces<\/p>\n
