Customized refractory board 1430C aluminum silicate fiber board furnace lining ceramic plates
Ceramic fiber board is a high-performance insulating product formed by ceramic fiber and adhesive in vacuum. It is flat, ceramic materials are evenly distributed, and has excellent heat insulation performance. Due to its low thermal conductivity and low heat storage, no inflation during heating can reduce energy cost and cycle time, and protect the refractory surface from thermal shock and chemical attack.
Ceramic fiber board has many other merits, such as solid texture, wind erosion resistance, excellent tenacity etc. It is an ideal material for building tunnels, furnace and many other insulating types of equipment.
Ceramic Fiber Board Features:
High rigidity and light weight
Low thermal conductivity
Resistance to thermal shock and gas erosion
Easy cutting and engineering, mechanical flexibility
Resists penetration by molten aluminum and other non-ferrous metals
