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: 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: Are fire materials poisonous after burning?: Refractories burning after the smell of toxic, gases are generally silica, alumina, sulfur oxides and so onRefractory material is not less than 1580 degrees of refractoriness, better thermal shock resistance and chemical erosion, low thermal conductivity and low expansion coefficient of non-metallic materials. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, refractory material, good heat shock resistance, resistance to acid slag, widely used.

Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.

Q: What's the refractory material?: According to the product shape, it can be divided into two kinds, that is shaped refractory and unshaped refractory. According to the chemical?property, it can be classified into three categories, that is acid refractory, neutral refractory and basic refractory, among which basic refractory and neutral refractory are commonly used, such as the basic refractory of magnesia carbon brick, fired magnesite brick, magnesite-chrome brick, magnesia-calcium brick, and the neutral refractory of high alumina brick, corundum brick, clay brick. Unshaped refractory includes: castable, ramming mass, gunning mix, coating material, dry vibration material, etc.!

Q: Concrete composition and function of magnesia bond used in refractory: The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick

Q: What's the fire endurance of hollow brick?: For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.

Q: what's the fire endurance of fireproof?panel?: Fire endurance of fireproof?panel is 3 hours, for example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. Fireproof board, also called fire endurance board, scientific name is thermosetting resin impregnated paper laminated wood.

Q: What kind of refractories do the anode baking furnace use?: Usually the clay refractory bricks will be able to meet the requirements

Q: What are the disadvantages of the refractory industry?: The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.

Q: How to choose the material of refractory?: Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
