LUYANGWOOL® CERAMIC FIBER BOARD / RCF Board
Luyangwool® ceramic fiber board is manufactured in a wet forming process using Luyangwool® ceramic fiber bulk and binders. Luyangwool® ceramic fiber board is designed for insulation applications experiencing vibration, mechanical stress and erosive forces. Luyangwool® ceramic fiber board can reduce energy costs and cycling times due to high insulating capability, as well as serving to protect refractory surfaces from thermal shock and chemical attack.
Features
Excellent thermal shock resistance
Can be machined, cut and shaped easily
High rigidity and light weight
Low thermal conductivity
Low heat storage
Typical Applications
Furnace hot face lining in petrochemical furnace
Furnace hot face lining in ceramic kiln
Board over blanket hot face lining
Back-up insulation to brick & castable
Expansion joints
