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: 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: How is the grading of the level A new material fire insulation material?: The thermal insulation materials are generally divided into level A and level B according to the flame rating. Level A is the non-combustible material, and level B is the combustible materials. The level B material is to blame for the fire in Shenyang hotel in CCTV building a few years ago . At present, the level A materials are widely used, with some prices even cheaper than the level B material. A level is roughly divided into insulation mortar, phenolic board, rock wool board and foam cement board, ect.

Q: I want to know what is the slim in the refractory bricks: lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.

Q: What is the role of the vermiculite fireproof material?: The vermiculite fireproof slate is widely applied to construction, shipbuilding, metallurgy, electric power, aerospace and other fields by foreign countries. Vermiculite slate can be applied to furniture, firewall, ceiling, and can be used in the fire fighting access, coated steel, coated pipeline, real flame fireplace in the lining board, wall partition. It is characterized by non combustible, non melting, resistance to high temperature; permanent thermal insulation; sound insulation, non-toxic, smoke-free, green environmental protection; resistance to impact, good dimensional stability and durability of the excellent anti fungal infestation. It can be sawed, nailed, planed, drilled, it can be easily installed and constructed.

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof door. Fireproof door of level A can endure fire for 1.5 hours while level B 1.2 hours

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: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Of course, there are also some docks that need not be fumigated! But also according to the requirements of the port of destination guests, because customs clearance may be proof of fumigation!

Q: What kind of refractory decorative board has good quality?: The unique design and personalized style of well-known brand "transit" rank highest in the field of domestic refractory slab. It is one of the largest manufacturers of high pressure decorating refractory slab in China. The production base covers an area of 40,000 square meters and the annual output is 4 million. It passes the test of Quality Supervision and Inspection Center of National Fire Protection Building Material and ISO9002 certification. The products pass international standards such as 4586, the United States NEMA and so on.

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 ℃;>
