Product Description
High refractoriness fireproof high alumina refractory brick for heating furnace is made out of a naturally-occurring material known as bauxite. This material include aluminum hydroxide, which is what give the brick such great warmth resistance. High alumina refractory brick also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.
Features
1.High-temperature endurable .
2.Good thermal shock resistance .
3.High cold crushing strength.
4.Good resistance to abrasion and corrosion.
5.Good thermal spalling resistance.
6.High mechanical strength.
7.Good volume stability at high temperature.
Application
1.General use in heat containment unit form temperature 1500-2000°C.
2.Resistant to highest temperature for steelmaking operations such as ladle applications, sidewall,roofs, burner blocks, anchor brick for reheating furnaces and many other areas.
3.transition and cooling zones of rotary cement kilns, lime kilns , etc.
4.lower sidewall and bottom of aluminum refining,melting furnaces ,etc.

- 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?
- 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
- Appearance and quality: Choose the material surface smooth and beautiful, no stains, no damage to the material
- Q: The difference between rock wool and rock wool
- Rock wool can also be made with glass wool aluminum silicate composite made of rock wool composite insulation pipe.
- Q: Rock wool products and aluminum silicate acupuncture blankets are same
- Rock wool products and aluminum silicate acupuncture blankets are same
- 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
- Q: Rock wool board is inorganic composite insulation material
- Insulation material A-level fire is organic meet the inorganic meet resolutely
