- Q:what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q:What are fire?ratings of wall thermal insulation material?
- Grade A material has no ignition and is material with thermal insulation effect, anti-combustion material. Currently it mainly refers to inorganic thermal insulation mortars of vitrified micro bead, hole-closed?expanded perlite, rock wool,mineral wool,glass wool,cement base or gypsum base, inorganic thermal insulation mortars and self thermal insulation system of lightweight block. Grade B1 is nonflammable thermal insulation material, which is determined by fire endurance of this material. In addition, the division of the material of different parts is different! What is commonly seen, such as EPS / XPS insulation boards adding flame retardant through special treatment. Grade B2 is combustible thermal insulation materials, and what is commonly seen is EPS expanding polystyrene board and XPS extruded polystyrene board, that is, the general board. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Grade B3 is flammable insulation material. Thermal insulation material with polyphenyl foam as main material is commonly seen. Since this material is highly flammable, it has been eliminated external wall thermal insulation materials.

- Q:What is neutral refractory? Can refractory suppliers tell the main components of it?

- Q:What materials are needed to make the amorphous refractory bricks?
- Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.
- Q:What refractory material does cupola lining use?
- In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.
- Q:What are the characteristics of thealuminium oxide refractory?
- The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
- Q:What is the magnesium carbon refractory?
- The composition of refractory brick There are many types of raw materials of refractory brick, mainly divided into six categories: Soil, stone, sand, mineral, power and others. The first kind of raw material, soil: Aluminum soil, kaolin, clay, diatomaceous earth The second kind of raw material, Stone: Fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
- Q:What are the materials of white firebricks?
- White refractory materials 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 kind of material is refractory fiber?
- 1 Refractory fiber cloth can be divided into resistant to temperature of 600 degrees and 1000 degrees temperature resistant (short-term resistance to extreme temperature 1260 degrees). The thickness of two kinds of cloth is typically 1mm 1.5mm 2mm 3mm 4mm 5mm with the width of 25mm-- 1200mm. 2 Specially woven fiber is not easy to fall off, does not irritate the skin, has large tensile strength. It is white and inexpensive. After contacting with water, the tensile force will be reduced. The thickness of refractory fiber cloth whose resistance of temperature is 1260 degree is generally 2mm 3mm 5mm, and the width is 25mm - 1200mm. It has high temperature resistance, great tensile force, and it is non-toxic, white, resistant to fire and water. We can offer products with different specifications according to customer requirements. It has high temperature resistance, low heat conductivity coefficient, thermal shock resistance, and low thermal capacity; It has excellent high-temperature insulation performance and long service life; It has anti-melting and resistance to erosion of aluminum, zinc and other nonferrous metals; It has good strength under low temperatures and high temperatures; It is non-toxic, harmless, and environmental-friendly; It has convenient construction and installation; Specifications and models are 1.5mm - 6mm, with a general width of 1m, (nickel-chromium alloy wire reinforced, reinforced stainless steel wire, glass fiber reinforced, ceramic fiber coated fabrics, ceramics fiber slag cloth, sintered ceramic fiber cloth, ceramic fiber fumigation cloth). We can also provide other specifications according to customer requirements.
