Q:What kinds of refractory will be used in kiln of sintering ceramics?
High alumina brick, clay brick, insulating brick and silicon carbide plate.
Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?
The fly ash effect will continue to play a role in a considerable period of time, so the long-term strength keeps strengthening, the average age of 90 days of strength will grow 80%-100% more than the 28 days.
Q:Physical and chemical indicators of various refractory.
please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.
Q:What is the difference between wear-resistant material and refractory material?
However, the purity and the requirement are not the same. For example, brown emery is often used in abrasive paper, which doesn't matter. Refractory material uses brown corundum brick. The material used in texture and refractory material of abrasive is different. For example, it is to facilitate their forming and easy sintering. However, some other materials should be added when making brown corundum brick. In general, some top grade materials are used to make abrasive.
Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
who knows the classification of fireproofing glasses, how long is the fire-resistant time?
Q:How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
Q:Which are fireproofing external wall materials?
According to combustion performance, external wall thermal insulation materials are classified as Grade-A and Grade-B. Grade-A refers to incombustible material and Grade-B combustible material. A few years ago the fire in CCTV building and Shenyang Hotel were caused by Grade-B material. Currently Grade-A material is more commonly uesd and less expensive than Grade-B material. Grade-A material can be divided into thermal mortar, phenolic foam board, rock wool board, foam cement board, etc. Thermal mortar is easy for construction and unexpensive, but it is also easy for faking due tou its simple procesing. It is recommended to find a large factory whihc has gone through the formalities.
Q:Is aluminium oxide refractory material?
Aluminium oxide with 2030ºC melting point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to you.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
