Q:What's the poured refractory material?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:what's the application of fireproofing abs materials?
ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring,
Q:What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:What requirements should refractory materials meet?
Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.
Q:I wanna ask about the thermal insulation material fire resistant level?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. Thanks
Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?
Pay attention to the performance of the materials, and the use of non oxide materials!
Q:The classification of clay according to refractoriness, and what is the plasticity and plasticity index of clay?
Q:What is the offer of fire proofing thermal insulation material?
1. Fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 15 yuan 2. 1260 ceramic fiber cotton thermal insulation panel thermal insualtion aluminum silicate aluminium oxide fireproofing fibre board 20 yuan 3. non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber cotton blanket 28 yuan The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances.
