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: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: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 board is inorganic composite insulation material: Insulation material A-level fire is organic meet the inorganic meet resolutely

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

Q:Rock wool insulation material fire rating is how much: Fire protection and noise reduction of the elevator shaft of the building wall, the roof of the insulation, the firewall, the fire door, the large and medium diameter pipes, the small and medium sized storage tanks, the kilns, the thermal power plants, Boilers and other equipment insulation.
