Product Description
Chinese Refractory raw material resources are abundant, which are suitable for the production of various grades of insulating firebrick. Limiting temperature of use range from 900º C to 1650º C. Each grade of insulating firebrick is formulated to meet specific thermal and physical requirements. Top grade insulating firebrick 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 controlled, uniform lacuna structure. Each brick machined to precise size on all six faces. The maximum continue use temperature depends on application. If you have any question, please feel free to contact us.
Features
1. Low thermal conductivity
2. Low thermal capacitance
3. Low impurity content
4. High hot compressive strength
5. Accurate dimension
Typical application
Recommended for use as a primary hot face refractory lining or as back-up insulation behind other refractory in furnace, kilns, flues, refining vessels, heaters, regenerators, gas producers and main, soaking pits, annealing furnace, catalyst case and similar high temperature industrial equipment.
