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
4. Calcined Bauxite Images
5. Calcined Bauxite Specification
Silicon carbide (SiC) is made from quartz sand and petroleum coke( or coal tar), wood chips as raw material through high temperature smelting in electric resistance furnace.
6.FAQ of Calcined Bauxite
1). Q: Are you a factory or trading company?
A: We are a factory.
2). Q: Where is your factory located? How can I visit there?
A: Our factory is located in Ningxia, China. You are warmly welcomed to visit us!
3). Q: How can I get some samples?
A: Please contact me for samples
- 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 materials is silicious thermal insulation board made of?
- Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.
- Q: Who knows how many fire heat preservation material are there?
- They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
- Q: Does anyone know the difference between refractory and thermal insulation material?
- Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.
- Q: What kinds of refractory will be used in kiln of sintering ceramics?
- If it is ordinary ceramic, you can use ordinary clay bricks and high alumina brick, adding calcium silicate board, the insulating brick and cotton fiber.
- Q: Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?
- There is no difference between them because they are the coating with the same texture. But generally galvanized treatment is not necessarily needed for brushing fireproof coating. Fireproof coating and galvanized surface have relatively poor bond strength. So it is advisable to bursh trasitional lacquer or micaceous iron on galvanized surface.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- I only know that the Stone Town Youxian district with a fire stopping collar.
- Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?
- “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
- Q: What's the frequently used refractory material?
- Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
- Q: what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
