1.Structure of Silicon Carbide Description

Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.

Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.

2.Main Features of the Calcined Bauxite

Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.

3.Main usage of the Calcined Bauxite

1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

2.Bonded abrasive tools, lapping and polishing

3.Widely used as a metallurgical additive and refractory material

4.Refractory

Q:Why do magnesium oxide refractory bricks can be made into refractories?: Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.

Q:How to deiron refractory?: Deironing refractory can take physical methods into consideration, such as magnetic?separation, reselection, etc. And it can also take chemical methods, such as flotation.

Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?: The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.

Q:What are grades of refractory materials?: Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.

Q:How should refractory cement be used?: Types of refractory mortar Refractory mortar can be divided into the following types: casting of fire mortar: also known air setting fire mortar. It is used as a protective refractory layer in the kiln head burner, as a refractory material in some parts of preheater, and it is generally constructed by grouting. b: Insulation fire mortar: It is used to repair the deformed plane of the kiln shell, or for thermal insulation of the roof in the cooler. Refractory mortar: It is also known as thermosetting fire mortar, mainly used in brick masonary. When using, we must add the glassy water to stir. (silicic acid sodium, water, NaSiO3, H2O). General DiDOTECT 135 (having a heat resistance of above 1350 degrees Celsius) SK34 is used in the kiln tail. DiDOTECT 150 (having a heat resistance of above 1500 degrees Celsius). SK35 Couprit 160H is used under high temperature, and it is mainly used in the kiln head coal injection nozzle.

Q:Physical and chemical indicators of various refractory.: There are too many of them.

Q:What are the raw materials of refractory?: Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as

Q:What are the materials of white firebricks?: The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~

Q:What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q:What are the characteristics of magnesium fireproof plate: Fire Excellence: Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature. Waterproof and moisture proof: Glass magnesium plate functions steadily whenever weather is dry and cold or humid and damp, not influenced by condensed water drop and moist air. Even air dried after soaked in water for a few days, no deformation, it will not go out of shape, turn soft, or absorb moisture After testing, the board has no water permeability. Light weight and seismic resistance: Low overall plate density of 0.8-1.2g/cm3 reduces the building's load, and the weight of building interior wall by over 60%, and increases the use area by 5-8%. Its lightweight is conducive to anti-seismic, can effectively reduce main cost of foundation and structure. Superior strength: Magnesite has special 5.1.8 phase covered fiberglass cloth and good toughness of plant fiber. Altough glass magnesium fireproof plate is light, it has tight structure, good stability, wood-like toughness, outstanding performance in impact resistance, compressive strength, tensile strength equal rigidity and toughness, with flexural strength up to 322kgf\cm2 (vertical) and 216kgf\cm2 (level of) as well as impact strength of 25MPa.
