Zibo Jiuchuan Material Co., Ltd.   (JCBN GROUP) 

*- Refractory Professional Manufacturer and Exporter.

Products: Refractory bricks, unshaped refractory, refractory fibre, landscape brick, etc.

Insulation bricks are classified under temperature between ***0ºC and ***0ºC, manufactured 
from high purity alumina clay by mixing, press-forming, drying, sintering and machining. 
Bricks contain carefully-graded organic fillers which are burned out during sintering to give 
a uniform controllable pore structure. This technique makes product feature low thermal conductivity 
and excellent heat insulation

 

Refractory Insulation brick can be used as a hot face lining directly exposed to the heat 
or as a backup insulation layer in iron and steel mills, non ferrous foundries, petrochemical, 
ceramic, glass, cement and oil fired electric power generating plants.

 

ADVANTAGES: 
Light weight and low thermal conductivity allows thinner furnace walls 
Maintain stable structural strength throughout ambient to maximum service temperature 
Low heat storage results in rapid cooling and heating operation 
Low iron and impurities to enhance reducing atmosphere 
High thermal shock resistance in preventing spalling 
Non standard sizes and shapes are available upon request 

APPLICATIONS: 
Ceramic shuttle kilns Metal heat treatment furnaces Steel billet reheating furnaces 
Oil refinery heaters Laboratory furnaces.

Our insulating bricks mainly include fireclay insulating brick, high alumina insulating brick, 
mullite insulating brick, K**3 brick etc.
