Insulating Firebrick
Description
Insulating Firebrick are made from high-purity refractory clays, temperature of use ranging from 1100 oC to 1700 oC, each grade is formulated to meet specific thermal and physical requirements.with graduated additions of alumina for higher temperature productscarefully grade d organic fillerthe organic filler burns out during manufacture to give a uniform, control pore structure.Features
low thermal conductive, low heat storagepuritygood thermal insulation, enable the use of thin-walled constructionsthe good alumina contents confer good refractorinessiow iron and alkali fluxcontent contributes to their stability to reducing atmospherethese can be machined to special shapes, incurring fewer sections and jointsTypical Application
Recommended for use as primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kiln, flues, heaters, regenerators, stress relieving furnaces,etcType | TJM23 | TJMB5 | TJM26 | TJM28 | TJM30 | ||
