Thermal insulating refractory brick for furnace

Product Description

Introduction of refractory brick

Insulating brick is sintered mainly with supper-fine bauxite charlotte and propr additive by a method of EPS ignition loss. Refractory high alumina EPS insulating brick for heating furnace is a kind of insulation refractory product, taking bauxite as main raw material and including not less than 48% of AL2O3.

Characteristics of refractory brick

1.High porosity

2.Small volume density

3.Good insulation effect

4.High mechanical intensity

5.Small thermal conductivity

6.Long service life

Application of refractory brick

1. Building materials for blast furnace

2. Building materials for hot-blast stove

3. Building materials for coke oven

4. Building materials for steel making furnace

5. For construction material in steel industry

6. For ladle

Q: What does the rock wool board look like?: Rock wool board to basalt as a material, after high temperature melting processing into artificial inorganic fibers, with a light weight, thermal conductivity, heat absorption, non-flammable characteristics

Q: What role does dolomite play in rock wool products?: Polyurethane is a field foam molding, process equipment is simple, easy to operate, you can spray can also be poured, in any complex roof construction operations

Q: Rock wool products are divided into several categories: Rock wool with a light weight, non-combustible, small thermal conductivity, sound absorption performance, good chemical stability and so on

Q: How to judge the quality of rock wool: Heat load shrinkage temperature: heat load shrinkage temperature used to characterize the rock wool board moisture and heat stability, is to wet the rock wool product samples soaked in the gradual heating of water, rock wool products at a temperature of 643 degrees will begin to shrink , So rock wool products load shrinkage temperature of 643 degrees, that is to say in the outside temperature of 643 degrees when the rock wool board will be deformed.

Q: The difference between rock wool and rock wool: Flexible, medium strength rock wool board: for building walls / roof insulation, fire, sound, such as curtain wall, wall partitions, elevator wells, etc

Q: Rock wool products and aluminum silicate acupuncture blankets are same: No, rock wool is the external wall insulation, silicate Lu power plant with more

Q: Rock wool insulation material fire rating is how much: Yanmian, mineral wool and its products are slag and basalt and other natural ore as the main raw material, the high temperature melt fiber, adding the right amount of adhesive processing
