CT-23 Brick Insulating Firebrick for Industrial Furnace Lining
Description
- CT firebricks 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 products
- Carefully grade d organic filler
- The organic filler burns out during manufacture to give a uniform, control pore structure.
Features
- low thermal conductive, low heat storage
- purity
- good thermal insulation, enable the use of thin-walled constructions
- the good alumina contents confer good refractoriness
- iow iron and alkali fluxcontent contributes to their stability to reducing atmosphere
- these can be machined to special shapes, incurring fewer sections and joints
Typical 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,etc
