We offer the most extensive range of insulating bricks products in the world, and access to unparalleled expertise in thermal engineering and furnace design. Our lightweight, precision-made insulating firebricks help our customers to reduce their operating costs by saving energy.
NR Insulating bricks is made from alumina content ranging from 35% to 60%, it can provide low thermal conductivity, low heat storage capacity and high strength, Save heat consumption as it is designed to allow heat losses, the insulating firebrick can survive temperature 900-1400 º C and then decrease weight of furnaces because of its lighter weight.
NR Series Insulating Bricks
NR series insulating bricks are a kind of highly efficient, energy saving, low-carbon,environmental protection advanced products which are manufactured according to ASTM standard. NR series products are the best lining and insulation materials in all types of industrial furnaces in the field of Metallurgy, Aluminum, Petrochemical, Ceramics, Power and Glass. They can be applied as heat insulation or no-melt erosion parts of the working layer.The products have been widely used in the following furnaces and achieved satisfactory results.
Metallurgyindustry: Blast furnace, Hot blast stove, Reheating furnace, etc.
Petrochemical industry: Ethylene cracking furnace, Hydrogen production furnace, Primary reformer furnace, Reheating furnace, etc.
Ceramics Industry: Roller kiln, Pusher kiln, etc.
Glass industry: Glass furnace regenerator, etc.
Carbon Industry: Carbon roaster, etc.
Aluminum electrolytic industry: aluminum reduction cells,etc.
Other industries: Tunnel kiln, Shuttle kiln, etc.
Low Thermal Conductivity: More porosity brings excellent insulation effect,energy saving.
High Crushing Strength:High crushing strength under thermal state, volume stability.
Low Heat Storage: Little thermal storage when absorb more heat, energy saving effect is obvious.
High Purity: Low content of iron, alkaline and metal impurities.
Accurate Dimension: Precise brick size by machining, cutting and grinding special shapes, expediting bricklaying.
