INSULATING FIREBRICK

KEYWORD：
insulating firebrick , insulation firebrick, insulating brick, heat insulation, refractory brick for oven.

North Refractories Co.LTD Insulating Firebrick Branch Specially produce ranges of high temperature insulating fire brick(IFB) with a application temperatures from 2,300°F (1,260°C) to 3,200°F (1,760°C). NRCL produce typical grade bricks and meanwhile accept orders for specific thermal and physical requirements.

Made from high purity refractory clay and other ceramic raw materials by mixing, press-forming,

drying, sintering and machining. The IFB 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.

Insulating firebrick can be applied 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 constructions.

Advantages

Low Thermal Conductivity
The light weight and low thermal conductivity of NR IFB make it possible more thinner furnace walls in constructions, more efficient and lower cost with energy saved.

High Strength

The high compressive strength of NR IFB maintains a self-supporting stable structures at elevated temperatures. IFB could be used together with dense fire bricks to improve the strength of whole construction.

Low Heat Storage
Low heat storage results in a more fewer fuels will be used during a rapid cooling and heating operation than the dense bricks.

High thermal shock resistance
NR IFB has a good performance in preventing spalling which is adversely for the life span of furnace linings.

High Purity

NR IFB is low in impurities and because of this they will enhance the refractory performance in many furnace constructions with a controlled atmosphere.

Precise Dimensions

NR Insulating Fire Brick are machined to precise dimensions which could make the refractory linings more quickly, exactly and easily , the more precise the less heat loss through the joints.
