Black silicon carbide supplied by cnbm

Silicon carbon is a new kind of reinforced steel-making deoxidizing agent and ideal thermal insulating agent.it 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%.

Advantages:

(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:Can refractory be used as sealing element?: It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.

Q:What's the organzational structure of refractory material?: Ingredients (harmful); phase composition. The main components of refractory material include chemical composition and phase composition. The addtional components include main crystal phase, matrix, crystal phase, chemical composition

Q:For refractory, what is critical particle size? Thank you.: For example, in refractory technology, if there is an express of equal to or lower than 0.008mm, 0.008 refers to critical particle size. The main criterion for judging performance of three major continuous casting is the major three normal temperature indexes (compressive strength and anti bending strength at normal temperature, apparent porosity and bulk density). Does this criterion have any defect? How to do multiple test if high-temperature index introduced? Carbon bond is one of the three major castings. How does it form? What do you think of it? Hope someone explains it for me. Thanks a lot!

Q:Fefractory of aluminium oxide.: It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.

Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q:what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.

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:What is the material composition of the new fire-resistant coating?: New fire-resistant coating generally consists of base material, dispersion media, flame retardants, fillers, additives (plasticizers, stabilizers, waterproofing agents, moisture, etc.). (1) Base material is the basis of the composition of the coating, and it is the main film-forming substance, playing a decisive role in coating performance . For fire-resistant coating, its base material must be capable of matching with the flame retardant to constitute an organic fireproofing system. The base material commonly employed at home and abroad includes inorganic and organic film-forming material. Inorganic film-forming materials include silicate. Si03, K2 Si03Na2 Si03), silica and phosphate [Al. (HPO.). ] ect. There are a wide range of organic film-forming substance, usually flame retardent organic synthetic resins, such as phenolic resins, halogenated alkyd resins, polyester, halogenated olefin resins (such as vinyl chloride resin), amino resin (melamine resin, urea resin, etc. ), tar-based resins, furan resins, heterocyclic resins (e.g., polyamide-imide, polyimide, etc.), organic elements resins (e.g. silicone resin), rubber (halogenated rubber such as chlorinated natural rubber) and so on. There are numerous latex taking water as solvent. www.hc3600.

Q:What are the chemical composition of refractory cement?: Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.

Q:What are the materials for refractory materials? What are their names?: Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
