$High Alumina Calcined Bauxite Ore For Refractory$

Q:What are the types of refractory sealant?: Refractory sealant has low exothermicity and will form a hard corking content during burning, it includes: Liquid polysiloxane has at least two active groups selected from alkoxy, hydroxy and alkenyl; a cross-linking agent, a catalyst, a reinforcing filler and wollastonite. These cured silicone rubber sealant has low heat release and will form a hard coking content structure while buring. Refractory sealant composition can be used in sealing structure to prevent flames, air and other steams passing. 1. In a liquid organic polysiloxane polymeters, each R1 is independently selected from the alkyl, aryl, alkenyl and haloalky which has 1-18 carbon atoms, and each R2 is independently selected from the hydroxy, alkoxy, alkenyl, and X is an integer from about 10 to 1,500. 2. A crosslinking silicone compound having at least 3 silicon-bonded eactive groups. 3. A R2 pressed of silicon bonding capable of promoting component A. 4. Wollastonite and a selective reinforcing filler.

Q:What are the materials of white firebricks?: The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~

Q:Who knows the classifications of magnesia refractory?: Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.

Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.

Q:How to divide the fire resistant level of construction thermal insulation materials?: Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.

Q:what's the standard of fireproofing material?: Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.

Q:Which refractory is suitable for the tunnel kiln?: Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.

Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?: How long is the fire resistance time of the AAA fire resistance rolling shutter door?

Q:How can refractory material of the electric furnace be used for longer.: Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life

Q:What substitutes are available for high-end refractories in addition to zircon sand?: If you want to use environmentally friendly products, please use recycled Mo powder.
