Q:Kinds of refractory mortar
It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
Q:what is the grading standards of external wall thermal insulation materials?
1. combustion performance of insulation material rates A EPS sea capacity module, rock wool, glass wool, foam glass, ceramic foam, foam cement, perlite obturator, etc. 2. combustion performance of insulation materials rates B1 Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule3 combustion performance of insulation material rates B2 Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 A graded insulation material is fire proof, but its thermal insulation performance is not so as organic XPS \ EPS. I feel the best insulation materials are Hairong EPS module. it is both insulating and fireproof and cheap. Insulation materials in the domestic market each has its shortcomings. Choose of materials should based on actualities in construction.
Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Seeing whether it can affect the usage of the refractory material, and seeing to reduce the impurity, what's the condition of temperature of the liquid phase. Practically, whether it has any difference if you can improve, load under load and creep and reduce the impurity content. In the refractories, producing liquid are the influence of impurities, high temperature resistant strength, compared the use of the refractory material temperature: testing compressive strength after burn. If there are any impact: knowing the main crystal phase of matrix composition and content, improving the content of the main crystalline phase can improve the high temperature performance of refractory materials.
Q:How to prolong the furnace age of Induction furnace by using fireproof materials?
magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
Q:How to divide the fire resistant level of EVB?
1. The thermal insulation material of level A combustion performance: Inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you!
Q:What's the fire endurance of A grade fireproof glass curtain wall?
An hour and a half, an hour, and half an hour. As a key step in the home fire prevention, fire door is particularly important. According to the fire endurance and heat insulation performance, it can be classified as follows: A class fire door with fire endurance of no less than 1.5h; B class fire door with fire endurance of no less than 1h; C class fire door with fire endurance of no less than 0.5h. We can choose according to different needs, while A class fire door and B class fire door are now commonly used. Fire door has great varieties, and the material it uses is also of wide range. It includes stainless steel fire doors, glass fire doors, steel fire doors, etc. The most important feature of fire door is its fire resistance period. The main difference between A class fire door and B class fire door lies in their fire endurance, of which the former is no less than 1.5h, while the latter is no less than 1h. Difference between A class fire door and B class fire door also lies in their fireproofing material. That is the thickness of the built-in fire prevention board, of which A class fire door is 52mm, while B class fire door is 46mm. Therefore A class fire door obtains longer fire resistance period than that of B class fire door and gains better fireproof performance. A class fire door and B class fire door also differ in the places they are used. A class fire door is generally used in important fire fighting access of machine rooms, warehouses and oil depots, etc. and flammable and explosive public places, while B class fire door is generally used in the ordinary fire fighting access of some ordinary buildings. But B class fire door is more widely used than A class fire door.
Q:What is the criterion of entry of refractory clay industry?
Chemical composition of refractory clay is one of the important factors affecting its quality. Al2O3 is the beneficial part of refractory clay, and it mainly exists in aluminum hydroxide minerals (diaspore, boehmite, gibbsite), and it also exists in aluminosilicate minerals (kaolinite, illite montmorillonite, etc.). In general, the content of Al2O3 in soft and semi-soft clay is 30% to 45%, the hard clay is 35% to 50%, and high alumina clay 55% to 70%. Fe2O3 mainly exists in hematite, magnetite, goethite and siderite, and is the main harmful component of refractory clay. There is no evident law on the content of Fe2O3. The content in high alumina clay is 0.5% to 2.2%, hard clay is 0.5% to 2.5%, and the soft clay is generally 1.0% to 2.5%. K2O and Na2O are harmful impurities in refractory clay, which mainly exist in illite and mica and other minerals, and the content varies greatly. CaO and MgO, etc., although they are harmful impurities, but the content is generally small.
Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!
