The B series insulation bricks have the characteristics of low thermal conductivity, high cold compressive strength, low thermal shrinkage, and small dimensional tolerances. It is inexpensive and can offer balanced properties such as strength and thermal insulation. Therefore, B series are widely used in place of other same grade products with similar service temperature.
>Hot Surface lining insulation of Dry furnace and Low-temperature furnace, Back-up lining insulation of Industrial furnace. (B1)
>Hot Surface and Back-up lining insulation of Industrial furnace. (B2-B6)
Increase the strength of compression, and it is used when the strength is insufficient in JIS B series. It is used for place of load-bearing, vibration or wear for various industrial furnace.
