High Aluminum Insulating Castable Refractory for High-temperature Industrial Kilns
The main material of our high alumina insulating castable refractory is Al2O3—SiC—C,there’s 2 types including baking casting material and free baking material, the width of iron runner is required above 2.4 meter, the depth is above 1.7 meter, it has a good performance in site operation, with easy repair, tapping iron is allowed after pouring finished. Although the invest is more higher for once time, but it will be with a longer service life and a few mending work.

- The standard size of refractory bricks in our country is: 230mm × 114mm × 65mm; ordinary brick: 240 ×115 ×53, building blocks: (it is divided into blind hole and via) 240×390×190, 240×190×190, 240×90×190, 190×190×190, 190×390×190, 190×190×190, 190×90×190, 140×390×190, 140×190×190, 990×200×400, 0×390×190, 90×190×190, 90×90×190. Another is interlocked hollow block : 90×200×400，90×200×245，90×200×200，90×200×100，90×200×290，150×200×275，150×200×200，150×200×100，150×200×290.
- Q: What are included in roof thermal insulation fireproofing material?
- Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
- Q: How to divide the fire rating standards of insulation materials?
- The fire rating classification standards of insulation materials, 1. Insulation materials with A-level combustion performance: inorganic fiber spraying, rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. Insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
- Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
- The sand is used as the filling material for the bottom of the ladle. Zhengzhou real iron refractory Co., Ltd. is specialized in the production of non-ferrous industries. All kinds of refractory materials used in glass kilns and cement kilns are sold directly by manufacturers. The prices are reasonable.
- Q: Who knows about the grade C fireproof door materials?
- I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.
- Q: What is required to do refractory material?
- What kind of refractory material? It’s too extensive.
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
- Q: Who knows what kind of fire protection material is better?
- Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
- Q: Classification of porosities in refractories and their effects on properties
- The pores in refractory include open pores, through pores and closed pores.
- Q: Which fireproofing materials factory is the best in Xiangyang?
- Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
