Grinding Black Silicon Carbide

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. It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze,aluminum, stone, leather, rubber, etc.

Green and Black Silicon Carbide with High Purity SiC CNBM

Q:Who knows about the B-level fireproof insulation materials?: Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.

Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?: there are different temperatures in various parts of the blast furnace, thus using different types of refractory.

Q:What's the fire resistance rating of the exterior fire?retardant?coating?: First of all, fire retardant coating has no class distinctions. Buildings fire resistance rating is generally classified as follows: I grade fire resistance, II grade fire resistance, III grade fire resistance, IIII grade fire resistance. Buildings with I grade and II grade fire resistance are much common. According to the coating thickness, exterior fire-resistant coating for steel structure can be classified as follows: 1. Exterior thin fire-resistant coating for steel structure, 2. Exterior ultra-thin fire-resistant coating for steel structure, 3. Exterior thick fire-resistant coating for steel structure.

Q:What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace

Q:What are the fire endurance requirements of class A fire resistant door ?: The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof?board framework (filled with perlite) fireproof?board panel. !

Q:What is refractory?: Refractory is an inorganic nonmetallic material with minimum refractoriness of 1580 ℃. Now, refractory is not defined merely by judging that whether its refractoriness is at above 1580 ℃. Currently, refractory, an inorganic nonmetallic material, are widely used in metallurgy, ceramics, power and other industrial fields.

Q:What kind of refractories do the anode baking furnace use?: Use refractory bricks.

Q:What is the fire endurance of fireproof glass cotton?: of course,A level is better. A-class is non-combustible, class B is fire retardant, rock wool fire resistance is 800 ℃, glass wool fire resistance is 450 ℃ , class B has a relatively better thermal insulation effect, hope it can solve your doubts.

Q:What are the models of bauxite with high alumina?: China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.

Q:Refractories for iron-making blast furnace?: Cement kilns?
