Q:What is the function of refractory material?
Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
Q:How to solve the shell, the crack problem of refractory material in the process of forming.
Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
Q:What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q:What is the difference between the fire rating and the fire resistant level of the fire-fighting equipment?
Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
Q:What are included in fireproofing materials?
There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire retardant material and its products, textile, fire retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof sealing material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of toxic gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.
Q:What is the quote of fireproof and soundproof materials used in KTV?
1. fire retardant, sound absorbing sheet,eggs,pyramid,sound-absorbing material, piano room, studio, KTV, with glue on the rear, 15 Yuan 2. bar, KTV, fireproof sound insulation cotton, sound-absorbing materials, studio, eggs, drum practice room, sound-absorbing and sound insulation materials, pyramid, 25 Yuan 3. fireproof wood excelsior absorbent, sound absorbing board, wall ceiling decoration materials, materials, theater, KTV, wood color fiberboard, 30 Yuan.
Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
Q:What kinds of fireproof materials does the safe use?
Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
Q:What a blast furnace refractories generally?
refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
