China Fire Clay Insulating Bricks Refractory, Find details about China Fire Clay Brick, Refractory from Fire Clay Insulating Bricks Refractory
Product Description:
Fire clay insulating bricks refer to lightweight refractory bricks containing Al2O3 30%-46%, whose main principle is clay clinker or light clinker and plastic clay. It is usually produced by combustible method, or chemical method or foam method, thus forms porous structure.
Based on the principle of clay clinker or light clinker and plastic clay, clay insulating fire brick is usually produced by the combustible method, or the porous structure can be formed by chemical method or foam method. Therefore, It can ensure that the furnace wall loses less heat, and the cost of fuel will decrease accordingly. Fire clay insulating bricks also mean less heat storage, so the heating and cooling are faster, allowing for faster periodic operation. And it is suitable for the temperatures between 900ºCand 1650ºC.
Features:
1. High refractoriness, high-temperature endurable.
2. Good thermal shock resistance.
3.Good volume stability at high temperature.
4. Good corrosion resistance.
5. Good spalling resistance and wear resistance.
6. High mechanical strength.
7. High-temperature creep rate is low.
Application:
Furnaces and kilns in metallurgy, steel, power, chemical industry
Insulating layers of various of thermal processing equipments,such as hot blast furnace, coke oven, glass kiln
Electric power and machine building
Linings in parts of furnace without strong high-temperature molten material erosive.
