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?: Pu hard foam layer can be firmly bonded with the base layer, the adhesive strength can exceed the tear strength of the foam itself, so Pu hard foam and the formation of the base layer, easy to delamination, to avoid the water along the interlayer

Q: Rock wool products are divided into several categories: In the rock wool by adding special adhesive can be processed into rock wool board, rock wool stave, rock wool insulation and other products, as the building insulation, insulation, cold, sound-absorbing material

Q: How to judge the quality of rock wool: How to judge the quality of rock wool

Q: The difference between rock wool and rock wool: Yanmian tube is a kind of rock wool insulation material mainly used in the pipeline. After the natural basalt is melted by high temperature, the artificial inorganic fiber is made from the high speed centrifugal equipment, and the special binder and dustproof oil are added. Temperature curing, made into a variety of specifications, different requirements of the rock wool insulation tube

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: Rock wool products are: rock wool board, rock wool tube, rock wool felt, rock wool insulation and so on
