Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?
On the other hand, the turbulence is severe, and the side wall of the tundish is washed into the liquid steel and the service life of the lining of the tundish is reduced. In order to solve this problem, China 5%% honing develops a tundish anti turbulence pad, which is made of Al2O3>75% high alumina castable. Anti turbulence pad mounted casting ladle and tundish flow impact zone in the bottom of the flow out of the steel ladle nozzle casting hole center back in the anti turbulence pad repeatedly to consume the kinetic energy of the fluid flow, thereby reducing the steel flow speed, avoiding turbulence.
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 ℃;>
Q:Why the corundum can be used as refractory
Corundum has high refractoriness, so its high temperature performance is very good.
Q:Is refractory material harmful to human body?
Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
Commodity concrete stations can not be produced in general, and are made by professional fire resistant concrete manufacturers.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
It belongs to the refractory industry, which has its own trade association.
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof panel, 7.gypsum board Hope to adopt my opinion
Q:What are the refractories for converter?
Magnesia carbon material with large surface repair vessel, in addition to supporting the use of magnesia and magnesia cement.
