Product Description:

Features:

 

1. Strong glass corrosion resistance and high thermal shack stability.

 

2. Good RUL, wear-resistance, dregs-resistance and alkali corrosion resistance.

 

3. The products are adopting superior material, with process by special arc furnace forming it. This fused cast technology got nearly no suffer from electrode pollution. They can be widely used in the lining of glass furnace, the chemical industrials, metallurgical furnace.

  

Our company can produce serious specification fused cast 33#, 36#, 41#AZS block for glass furnace and its output is over 5000tons per year. In the enormous working premises—more than 6600square meters, there are one 5tons outside cooling electric arc furnace, high-power transformer, thaw craft with computer control system and internal advanced fused cast refractory umeral control grinding equipments according to its body producing ability.

Q:Does anyone know about the fire resistance period of thin fireproof coatings?
The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:Who knows what material is in the center of fireproof rolling curtain?
Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you
Q:What kind of material is good for cabinet fireproof board
Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling. Fiber cement fireproof board is a kind of new material increasingly gets popular with superior heat insulation, sound insulation performance, belonging to the A1 level fire materials 1, Suzhou total surplus purification A-grade fireproof rock wool colored steel rock wool board range of applications: Partition ceiling material: Rock wool reference price: On a square 58.00/2 meters, Huarui thermal insulation fireproof materials aluminum silicate refractory aluminium silicate A-grade fireproof heat insulation aluminium silicate plate temperature: 1000 core material: Reference price for aluminum silicate fiber cotton: $3500.00\ ton
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
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:How long is the duration of fire resistance that fireproof window of level B can endure?
The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
Q:What effect does aluminium powder play in refractory bricks?
Aluminum powder is the main temperature resistant material ~ ~ ~ ~!
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
To sum up three versions of GB8624 (1997, 2006, 2011), fire rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire rating of external wall thermal insulation materials.
Q:can slag tailings be used to be the base materials of refractory materials ?
perhaps not, because it has many pores.
