Product Description

Description:

Manufacturing Good Quality Silicon Carbide

Silicon carbide is made of silica sand, coke, wood and other raw materials by resistance furnace smelting at high temperature. It hassteady chemical composition, anti-abrasion, anti-corrosion, high temperature resistance, good heat conduction and so on. Now SiC produced by China's industry can be divided into black SiC and green SiC.

Use:

They are mainly used in four big application fields: functional ceramics,refractories, abrasives and metallurgical raw materials .

SiC is suitable for cupola and electric furnace.

As deoxidizer, it is widely used in foundry and steel industry. It can rapidly increase the temperature of molten steel, shorten smelting time, at the same time, it also can play deoxidizing, increasing carbon and silicon, heating up role. It can improve the quality of steel.

Characteristics:

1. Increasing carbon and silicon, reducing the consumption of

carburant,ferrosilicon and other alloy, saving the cost of per ton steel.

2. AS SiC is oxidized, it can release a large number of heat energy, reduce the cost of electric, lower the cost of production.

Chemical composition:

Q:Detailed description of magnesia dolomite refractory material?: The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.

Q:Which kind of refractory floor is easy to use? ?: Fireproof wood floor includes three types, and according to your requirement, I think that the third type is more suitable or is easier to use. Here are the three types, and you can choose form them. A. Wear-resistant composite solid wood floor It is also known as super durable multi-layer solid wood floor. Its surface is inorganic glass fiber material and special paper impregnation thermosetting amino?resin, composited with solid wood base materials like plywood or core-board. And also, its front is wear-resistant layer while the back is balance layer, then hot press it into grooved and tongued floor. This is a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, comfort as solid wood floor, and stability as composite board. B. Fire-resistant wood-plastic composite decking board Wood-plastic composite decking board is not the wood floor in the traditional sense, but a composite material, also known as plastic wood. It is formed by high molecular improving and processing natural fiber, such as recycled plastic and wood fiber. It not only has the same advantages as plastic and wood, but alos has certain fire resistance, thus it is a environmentally friendly material with much development potential. C. Fireproof strengthened composite wood floor It is the so-called fireproof and fire retardant floor, fiber board, plywood and chipboard as its base materials. It is coated with fireproof coating and impregnated paper, and after fireproof and fire retardant technical process, it becomes a composite wood floor with some fire?retardant level. Its features are more partial to that of laminate floor with stable performance, steady structure and good durability.

Q:What are the requirements for the performance of refractory materials?: Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.

Q:What is the material composition of the new fire-resistant coating?: The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.

Q:What are the standards of refractory concrete ?: It can be divided into: 1. Ordinary refractory concrete Aggregates used include high alumina, clay, silica, basic materials (magnesite, chromite, dolomite, etc.) or special materials (carbon, silicon carbide, zircon, etc.). It can also use several combination of refractory material. 1. Thermal insulated refractory concrete It is mainly formulated with refractory light aggregates. The light aggregate used can be expanded perlite, vermiculite, ceramsite, porous chamotte, alumina hollow ball, etc. It can also be a combination of several refractory light aggregates or combination of the refractory aggregates. The aggluetination material used in refractory concrete can be high alumina cement, phosphate binders, water glass binder and clay, etc.

Q:Where do China and foreign countries do more refractory materials?: Zhengzhou Xinde yuan Refractories Co., the company's products have high alumina brick, clay brick, light insulating brick, wear-resistant pouring material, corundum castable, low cement castable with high strength, impervious material, material, plastic, and self shaping of various grades of cement and unshaped refractory materials. For different industries have antistripping high alumina brick, brick, alkali phosphate brick used in cement industry, boiler industry with various grades of wear-resistant brick, corundum brick, mullite brick and other forming material. Companies adhere to the "product quality for life, enterprise integrity as the foundation", in the fierce market competition, has won the trust and praise of many users. Refractory products are sold throughout the country and exported to Vietnam, India, South Korea, Pakistan, Iran and other Southeast Asian countries and regions.Companies adhering to the "quality first, reputation first, customer first" to the management of physical science, strong technical force, perfect detection means, advanced process equipment, stable product quality as the quality guarantee.

Q:What are the fireproofing materials of the external wall included?: According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!

Q:how to classify the fireproofing material levels A1 A2 B1?: their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into

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:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.
