- Q: Which brand of thermal insulating refractory is good?
- The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃
- Q: What characteristics do A grade external wall fireproofing material have?
- 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
- Q: About the market issues of thermal insulation material and refractory material.
- In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu
- Q: What kind of material is refractory fiber?
- Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
- Q: What a blast furnace refractories generally?
- Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
- Q: Which refractory quality inspection authority is good?
- Download refractory quality inspection LIRR in Henan is nationally recognized. Of course, it is an authority, but the cost is very high.
- Q: Which kind of refractory floor is easy to use? ?
- Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
- Q: what textures of furnace refractories are good?
- The common one uses the ordinary aluminous fireclay brick and GB / T 3994-2005 insulating fireclay brick. The ones with excellet texture are high-grade thermal insulation refractory brick and GB / T 3995-2006 high alumina insulating firebrick, whose model is A13, the texture is alumina, A13 50u, advanced heat insulating brick B5; intermediate heat insulating brick B2, and so on. Dolomite brick: The formation of coating is of good performance and corrosion resistance, but to some extent, there exsits the f-CaO in the brick, which is easy to hydrate, and hard to transport and storage, thus less using in the production. Magnesia-chrome brick: The formation of coating is good, so it is widely used for burning zone, but the disadvantage is poor thermal shock resistance, coupled with the highly toxic positive Hexavalent Cr, so the international countries that produce and use the magnesia-chrome bricks are gradually reducing. The production unit using this brick now, please find alternatives as soon as possible.
- Q: What are the uses of refractory materials of glass furnace?
- crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
- Q: What needs to be paid attention to in the construction of high- temperature refractory mortar?
- As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
