1.Description

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.

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:Does hardware construction materials contain refractory?: refractory includes one kind of building materials. It is a special material and not commonly used.

Q:What 's the highest temperature can magnesium plate glass resist ?: 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.

Q:how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q:What advantage and disadvantages it has compared to common fire insulation materials: Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem

Q:Refractory inquiries: Aluminosilicate refractory refractory material refers to SiO2-Al2O3 as the main ingredient, according to how much the Al2O3 content can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%) three.

Q:What are the materials of class A fire resistant window?: Environmentally friendily, non-poisoned non-peculiar smell, non-radioactive; non-combustible, fireproof, moisture-proof, corrosion-resistant; easy to operate, lightweight, high strength, themal insulation, sound insulation; able to be cut, planed, sawed and carved. It also meets GB8624 -2006A1 level non-combustible standards. Lightweight, high strength, anti-aging, corrosion resistance; meeting the GB / T20285-2006 Opium (AQ1) safety and environmentally friendly products; Foamed fire door core board specifications: 2100 × 900 × (26 ~ 65) mm; 2050 × 850 × (26-65), and many other specifications. I hope my answer can help you.

Q:who knows the requirements of refractory for forge furnace?: Requirements are as follows: 1, it should have enough refractoriness and softening point under a fixed load. Because under the effect of electric arc, inner surface temperature in different parts of furnace lining can reach 1500 ~ 1800 ℃. 2, it should have strong slag resistance. Because slag and smoke at high temperature penetrate through furnace lining to its internal lining, causing the melting of refractory, organization stratification, and even peeling?off. 3, it should have good thermal shock resistance. Because in the process of steelmaking, openning the oven door and lifting the furnace lid will make temperature of refractories in the furnace lining change rapidly, it might happen peeling?off and cracking, causing the premature failure of furnace lining. 4, it should have sufficient strength, because the furnace lining will be shocked when being loaded, vibrated when being tilted, scoured by metals,molten slag and air flow when boiling. 5, smaller thermal conductivity, lower electrical conductivity. Commonly used refractories for electric furnace include magnesia bricks, dolomite brick, high alumina refractory brick, siliceous refractory brick and magnesite ramming material,etc. owing to the different work environment of each part of the furnace,refractory used by each part is also different.

Q:What substitutes are available for high-end refractories in addition to zircon sand?: The composite sand powder can effectively replace zircon sand, with the same operation process, less operation time and environmental protection

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.
