Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?

While the refractory ceramic fiber cloth is different in high temperature resistance, and in general it can endure the high temperature of more than 1000℃. Ceramics in daily use and art ceramics: Bone china and Guangdong chinaware can generally endure the highest temperature of 1100℃. Jingdezhen porcelain and ceramics: They can generally endure the highest temperature of 1280℃-1340℃, and some special ones can endure the highest temperature of 1400℃. Industrial ceramics: Some of them can endure the highest temperature of about 2600℃. (alumina ceramics: their melting point is 2050℃, and boiling point is 3000℃).

Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?

The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.

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:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?

I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.

Q:What refractories are accessible with ease in daily life?

Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic?refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay?bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.

Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?

There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.

Q:How long is the duration of fire resistance that fireproof window of level B can endure?

Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?

2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
