- Q:Refractory net
- Foreign enterprises created not only for profit, but a career, hope to be able to last forever; domestic, especially private enterprises, most of them do not have such a vision, only to a loophole, cash, so never to do this industry.Welcome to discuss the statements of a school.
- 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:How to choose thermal insulation materials for flood heating?
- How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you
- Q:What kind of refractories do the anode baking furnace use?
- Use refractory bricks.
- 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's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q:How to count the construction costs of refractories?
- In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
- Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
- Q:Using what kind of melting aluminium furnace refractories is more appropriate?
- If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
