Q:What refractory material does cupola lining use
Refractories for ehongtianlu, Yong, eajliao, najhuo cupola, refractory (refraetoriesfo:Cupola, furnace) masonry cupola and related parts. The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.
Q:Introduction to refractory material
Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractories include structural property, thermal property, mechanical property, usability and operation property. Structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution,etc.. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, breaking strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, bonding strength, elasticity modulus. usabilities of refractories include refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, corrosion resistance to CO, conductivity, oxidation resistance, etc.. Operation properties of refractory include consistence, slump, fluidity, plasticity, cohesiveness, resilience, coagulability and hardenability,etc. I hope you can solve the problem with my answer.
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:What's the frequently used refractory material?
What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory castables, stemming, etc. Special Refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation board, etc.
Q:Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:As for fireproofing material rock wool and glass wool, which one is better?
First of all, glass wool and rock wool fireproof materials, rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.
