Q:Can anyone tell me what is the material of which the mould for refractory is made?
It is ordinary steel mould and it should not rust
Q:How can refractory material of the electric furnace be used for longer.
Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life
Q:which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
It depends on the composition of the ceramic material. If its composition is alumina and it is used by civilians, its normal use temperature is 1200℃; if its composition is alumina but it is for millitary use, it can endure the highest temperature of 2200℃.
Q:The classification of clay according to refractoriness, and what is the plasticity and plasticity index of clay?
Q:What are the common refractory insulation cotton material?
Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry Their common characteristics is fire resistant, applicable for buildings that have high requirement for fire resisitance level. Calcium silicate, aluminum silicate, asbestos, etc. can also be used for thermal insulation of high temperature heat transfer pipe. I hope my answer can help you
Q:who knows the fire resistant levels of fireproofing glass?
According to the fire resistance levels, it can be divided into three categories: Class A: a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Including composite flameproof glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting roof,ceiling screen,perspective floor and other construction components demading for transparency and fireproofing. Class B: Marine fireproofing glass, including porthole fireproofing glass and rectangular window fireproofing glass, surface glass pane is tempered safety glass, the inner surface glass pane material can be arbitrary selection. Class C: it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
Q:What is the importance of silicon powder in refractory processing?
in amorphousness it is mainly the mobility
Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
