Tk28 Insulating Firebrick (1538 Grade)

Insulating Firebrick with light weight has high mini-porosity arranged in average, keep furnace wall low radiation. They can be used for hot face lining directly exposed to the heat or as a backup insulation layer. Light weight means the lowest thermal storage, it's quicker to heat and cool, and permit rapid cycle work. They are used for 800°C~1600°C.
