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?: June 1981 test success Rock wool board is a new type of insulation, fire, sound absorption material.

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: Which rock wool board in the application of more interior decoration. Rock wool board specifications are usually as follows: long (mm) 900,100; width (mm) 500,600,700,800; thick (mm) 30,40,50,60,70

Q: How to judge the quality of rock wool: Burning performance: Combustion performance refers to all the physical and chemical changes that occur when the building material is burned or in case of fire. This performance is caused by the fire and flame propagation of the material surface, heat, smoke, carbonization, weight loss, and toxicity And other characteristics to measure. The burning performance of the products of rock wool products is zero.

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 ore blown wire, aluminum silicate is coke gem

Q: Rock wool insulation material fire rating is how much: With low thermal conductivity, the use of high temperature, fire non-flammable, construction convenience, energy-saving effect is remarkable, there is a high cost performance. Adiabatic with rock wool, mineral wool and its products for a variety of pipe insulation and fire protection
