Q: What are the materials of insulation firebricks?: The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.

Q: What's the fire?retardant material of roller shutter fire resistance door ?: Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.

Q: Procedures for producing common refractory materials?: The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.

Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?: Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department

Q: What is the material composition of the new fire-resistant coating?: New fire?retardant?coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.

Q: How should refractory cement be used?: Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.

Q: What kind of refractory bricks material is best?: 1, high alumina brick: The content of Al2O3 is more than 75. The refractoriness is higher than the clay brick. It has good resistance to acid, alkali and erosion and is suitable for cement kiln calcining zone and other places. It has long operation life, but the price is high. 2. dolomite?brick: Formation of coating has good performance, good corrosion resistance, but f-CaO is contained in bricks. It is hydratable and difficult to transport and keep, so it is less used in the production. 3. magnesia-chrome bricks: It has good formation of coating and is used for burning zone. The disadvantage is poor thermal shock resistant performance. Besides, positive Hexavalent Cr is highly toxic. Countries that produce and use magnesia-chrome bricks gradually decrease on the international. Now production units using this brick should find alternatives as soon as possible. 4. spinel brick: It is often used in transitional zone and has good seismic performance, good reduction resistance, but refractoriness is a little bit poor. 5. anti-stripping brick: This brick contains a small amount of ZrO. Martensite phase transformation happens to form thin crack during temperature-rise period. It has strong alkali?resistance, anti-stripping performance and good slag resistance. 6. phosphate brick: It has low refractoriness, but it has strong strength and good shock resistance. It is often used in grate?cooler, hot kiln hood, etc. 7. carborundum brick: It has high temperature resistance(1800 degree, softening temperature under a fixed load is 1620-1640), small coefficient of thermal expansion, high cold-resistance heat-resistance, abrasion resistance. It is suitable for cooling zone and kilneye. 8. silmo brick: It has good thermal shock resistance, high strength, good abrasion resistance, and is suitable for transitional belt.

Q: What's the type of fire proofing thermal insulation materials?: Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.

Q: what is the specs of thermal insulation refractory slab ?: Fireproof insulation specification is 1220 * 2420 1220 * 2420 * 8 * 9. HPL also known as the fireproof board is scientificly named thermosetting resin impregnated paper laminated wood, the abbreviation of which is HPL.Decorative high-pressure Laminate is fire-resistant building materials for decorative purposes. It is rich in surface color, texture and special logistics performance, widely used in interior decoration, furniture, kitchen cabinets, laboratory table, external walls.

Q: Do you know where I can buy refractories?: You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
