$Rotary Kiln / Round Kiln/ Shaft Kiln Calcined Bauxite for Refractories$

Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?: Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".

Q:What are grade classifications of the external walls fireproofing material?: 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.

Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.

Q:Why the refractories should be waterproof and wetproof: It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use

Q:I wanna ask what are the acidic refractories?: Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon?dioxide. There are the following: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.

Q:How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q:What are the best refractory materials in 2,400 Celsius degree?: and carbon fiber or nanomaterials.

Q:Who know about the knowledge of acid refractory material? Please explain in detail.: Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.

Q:On the problem of making refractory materials: But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!

Q:What are the main characteristics of the sic refractories?: 1. The usge temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand the dramatic changes of temperature and have a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
