$Refractory Castable For Industry Furnace$

Q: What kind of flexible fireproof material is really good?: The best one is grade A fireproof material. A-class fire flexible material adopts clay, stone, sand, cement blocks and other inorganic powder and modifier and product density is 2327 kg/m3. Upon examination, the combustion performance of this product is in accordance with the grade A specified requirements and additional classification meets A s2, d0, t0 level requirements. According to GB 8624-2006, the combustion performance of product reach A2 - s2, d0, t0 level.

Q: what's the application of fireproofing abs materials?: ABS is acronym of Acrylonitrile Butadiene Styrene )it is a kind of thermoplastic high polymer material with properities of high strength, good toughness, easy processing and molding. it has high strength, corrosion resistance, high temperature resistant, so it's often used in the plastic shell manufacture of instruments.

Q: How can refractory material of the electric furnace be used for longer.: Minimize mechanical shock, Electrical furnace commonly referred to must be electrical arc furance. The wall of electric arc furnace should be constrcuted with magnesite carbon brick. Its hearth permanent layer should be constrcuted with mansornary magnesia brick. High alumina brick is usually used to aviod furnace cover suddenly get hot and cold. But its service life is lower. At present integral casting furnace cover is made of alumina magnesia. Terminal will be created even without the use of refractory material. Consumption is much faster if using refractories material or whole knottiing mainly.

Q: Is fireclay corrosive?: No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!

Q: how is the high-temperature flame-retardant fibre board?: ------ Different category of high temperature materials including refractory and heat-resistant material, inorganic compounds, high-molecular polymer. refractory usually refers to an inorganic material that can endure temperature above 1580 ℃ . They are for building kiln, combustion chamber and other buildings that require heat resistance materials. It is generally made of quartz sand, clay, magnesia mineral, dolomite.

Q: What are the main components of refractory cement?: Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. 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. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.

Q: Which one is the best refractory material?: Resin bonded refractory is mainly abot aluminum magnesium carbon, and carbonaceous etc. Thermoplastic resins need to add the coagulant (Uto), ageing mixture for a period of time, so the production cycle is long. Hot hard resin is relatively not so complex, but it’s not as good as thermoplastic resins in thermoplastic binding.

Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?: Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
