Product Description:

Black Carbide Silicon SiC 92-95% Content

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:What are fireproofing materials?
1. With the tape made by double-coated flame-retardant and chemical defense surface adhesive and that only occurs charring with no melting drops and maintains good strength when meeting with fire as main material, and by the laminating-sewing-pasting process, clothing body and gloves are made and equipped with flame retardant, chemical defence, voltage resistant, and puncture resistant boots, the clothing assembly is constituted. 2. They are usually asbestos. Some of them have better quality and are made by wiredrawing of aluminum zirconium and silicon mixtures, and of course others are directly manufactured with some natural objects. 3. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. Coatings are usually those with fine powder, high density and good sealing. 4. Phenolic foam board can meet the requirement and its test temperature can reach up to 2000℃ under which it has no molten droplet but good integrality. Thermal Conductivity: 0.03W/(mk). It is non-flammable, non-toxic and smokeless! 5. The hollow ceramic micro-bead is good in thermal insulation and fire-retardance.
Q:Does the refractory material used in steelmaking all refer to refractory brick?
For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.
Q:Do you know where I can buy refractories?
A Address of Guangzhou Lingnan Refractories Co., Ltd. : No.1069 Guanghua 1st Road B Address of Guangzhou Aolian Refractories Co., Ltd. :
Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m³ can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What's the fire endurance of A grade fireproof glass curtain wall?
According to the latest requirement, fire door has three types of FMA, FMB and FMC, of which A, B, C refer to the class. Take FMA as an example, it refers to A class fire door (namely thermal insulation fire door). The fire endurance of these three types all can be 0.5h, 1.0h, 1.5h, 2.0h or 3.0h, and the specific fire resistance time needs to be determined by the design. Generally the design drawing will make clear of it. As to A class fire door, its fire endurance is 1.5h.
Q:how is the high-temperature flame-retardant fibre board?
Temperature refractory fiberboard is of high quality and not likely to be damaged. It is light and easy to install.
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:Who knows the new fireproof and thermal inuslation matertial?
New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.
Q:The classification of fire-resistant material
Refractory material cna be divided into common and special fire proofing material. Common fire proofing material can be sub-divided in to acid fire proofing material, neutral fire proofing material. and alkaline fire proofing material according to chemical properties. Special fire proofing material can be divided into high temperature oxide refractory, refractory compounds and high temperature composite materials according to the composition. In addition, it also can be divided into common refractory products (1580 ~ 1770 ℃), high-grade refractory products (1770 ~ 1770 ℃) and super refractory products (above 2000 ℃) according to the strength . According to the shape, it can be divided into block (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and irregular shape (refractory clay, refractory castable, ramming material and so on). According to sintering process, it can be divided into sintered product, fused cast product and melting jetting product.
