INSULATING FIRE BRICKS
Refractory firebricks with thermal insulation have a porous structure and excellent thermal insulation properties, resulting in low thermal conductivity and superior insulation. This allows for a decrease in lining thickness during shaft operation and a quick rise in operating temperature with less fuel, resulting in cost savings and improved productivity as well as energy savings.
