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: whether the fire resistant level of aerated concrete building blocks can reach the grade one?: Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.

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.

We can also provide other specifications according to customer requirements.

Q: What are the characteristics of magnesium fireproof plate: Fire Excellence: Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature. Waterproof and moisture proof: Glass magnesium plate functions steadily whenever weather is dry and cold or humid and damp, not influenced by condensed water drop and moist air. Even air dried after soaked in water for a few days, no deformation, it will not go out of shape, turn soft, or absorb moisture After testing, the board has no water permeability. Light weight and seismic resistance: Low overall plate density of 0.8-1.2g/cm3 reduces the building's load, and the weight of building interior wall by over 60%, and increases the use area by 5-8%. Its lightweight is conducive to anti-seismic, can effectively reduce main cost of foundation and structure. Superior strength: Magnesite has special 5.1.8 phase covered fiberglass cloth and good toughness of plant fiber. Altough glass magnesium fireproof plate is light, it has tight structure, good stability, wood-like toughness, outstanding performance in impact resistance, compressive strength, tensile strength equal rigidity and toughness, with flexural strength up to 322kgf\cm2 (vertical) and 216kgf\cm2 (level of) as well as impact strength of 25MPa.

Q: what kind of fireproof materials is used for high rise buildings?: First, fire resistance steel door: in the general real estate, developer uses more of fire resistance steel door. The mid-low-end doors are the earliest products and mostly widely used with longer servce time. The disadvantages are corrosions, thus it will rust, fade after being used for a while, and will affect the overall appearance. Styling lines are hard, not matching well with modern home decorative styles. Second, the stainless steel fire doors: anti-theft performance ,durable, stronger security. Compared to the general iron or mixed iron and steel security doors, stainless steel doors never rust and most importantly its uniqueness in addition to lasting bright color. Disadvantages: Stainless steel security doors are mostly silver, giving us dull feelings by seeing its appearance and color, lack of coordination. Third, glass fire door: high quality fire glass doors. recent years have seen wide application in office buildings and some high end public place, less in individual users. Compared to the current categories of timber, fire glass door is not only simple and luxury and durable.

Q: Who knows what kind of fire prevention materials are there?: 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.

Q: What are the materials used in refractory material processing?: AZS special refractory brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..

Q: What are the specifications of refractory kilns ?: Since the coefficient of thermal expansion of the basic brick is large, expansion rate is about 1-1.2% under 1000 ℃ The literature indicates that: "Under the condition that the temperature was raised to 1000 ℃ and stress in brick lining is relaxed, 300N / mm2 of compressive stress can be produced, which is equals to ten times structural strength of ordinary magnesia chrome brick, six times structural strength of magnesia chrome brick, dolomite brick and spinel brick, so any basic bricks can not afford, " the paper also pointed out that " heat expansion rate of kiln body can partially compensate for expansion rate of the inner lining of 0.2% -0.4%, which is 1/3 of thermal expansion rate of ordinary magnesia-chrome brick under 1000 ℃. However, it occurs under thermal equilibrium conditions. Thereby, the kiln should be dried slowly, allowing the temperature of the kiln body to go up slowly, thus the role of compensation can be played. " This is the key to using the basic brick. " Procedures of refractory for cement kiln "( tentative one) has clearly regulated baking and cooling of the kiln in the first section of the fifth chapters. In the heating process, in particular when the temperature is in the range of 300-1000 ℃, heating rate must be less than 60 ℃ / h. This is very clear in theory but it is difficult to implement.
