Product description
Light weight k23 soft fire brick is also named high-aluminium heat insulation brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulation heat. Refractory insulation thermal brick contains more than 48% alumina oxide.
Advantages of CH Refractories manufactured k23 soft fire brick:
Excellent thermal insulation properties: insulated firebrick have low thermal conductivity, which can effectively isolate heat transfer inside and outside the furnace and improve energy utilization efficiency. At the same time, it can reduce the temperature rise of the outer wall, protect the furnace structure and reduce heat
High temperature resistance: High-alumina polylight bricks use high-purity alumina as the main component and have excellent high-temperature resistance. In high temperature environments, it can maintain stable physical and chemical properties, is not prone to ablation and deformation, and extends its service life.
