Silicon Carbide for Grinding Wheel Nanufacturing made in China

Silicon carbon is a new kind of reinforced steel-making deoxidizing agent and ideal thermal insulating is used for deoxidizing. The usage dose is 1-4kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.



(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.


(2) Good hardness, longer life.


(3) Chemical washed and water washed good cleanness.


(4) Special treated products get higher purity, better toughness, and better grinding effect.

Q:What are the applications of refractory in petroleum?
It can be used in transportation of natural gas, filler of chemical equipment, security, insulation or even building materials.
Q:Does anyone know fire-proof material of fireproof wooden door?
Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm .
Q:Where is the development of refractory industry?
The rapid development of continuous casting technology of its related @ China @4 honing refractories develop and increase in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.
Q:What is the acceptance standard of refractory?
It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.
Q:How should fireproof building materials be ranked?
According to our national standard GB8624-97, the combustion performance of building materials are divided into the following levels: A class: Incombustible building materials: the material is almost incombustible. B1 class: Flame-retardant building materials: they are better in fire retardation. It is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material: It has no fire retardant effect at all, but is highly flammable with high fire risk. Hope my answer can be accepted.
Q:who knows the fire resistant level of fireproof gypsum board ?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. As for the Dragon brand, rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:Are there any differences between insulation and refractory materials ?
First, refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Second, insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.
Q:How to divide the fire resistant level of EVB?
According to the indicators of amount of smoke, heat value, burning rate, and ignition point, combustion performance insulation materials are divided into A (non-combustible), B1 (flame retardant), B2 (flammable), B3 (combustible). It can be divided into the organic and inorganic types: The organic includes polyurethane and polystyrene board, the inorganic the includes glass wool and rock wool. The price of organic is lower, and it is combustible materials, it will produce hydrogen cyanide and other toxic gases when burned, the inhaled would die. The inorganic material is completely non-combustible insulation material.
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.
