Product Description:

Brown Fused Alumina for Refractory, BFA sands, Abrasives

is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials

Q:What refractory material lead smelting furnace needs?
Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
Common faults and causes of magnetic separator. 1. Motor of magnetic separator is overheated and its sound is not normal. Reasons for this failure are: 1) lubrication of bearing is bad or badly worn; 2)fan blade falls off or wears; 3)bad contact of switching circuit or disconnected to run a single phase; 4) voltage is too low. 2. Reasons for this failure due to overheated speed reducer are: 1) lack of oil or poor kerogen; 2) wear between gear and worm, or poor mesh; 3)poor lubrication of bearing or serious wear. 3. The sound of magnetic separator during operation is abnormal, lattice ball mill. Cylinder is stuck by obstacle, and even the cylinder can not rotate. The bottom box vibrates. Reason for this failure is often that it is stuck by objects in drag flask, otherwise magnetic patch falls off so that the cylinder screaks and pierce tube when it is serious. At this time, car should be stopped for maintenance and troubleshooting. Only when we master common faults and reasons of magnetic separator can we timely identify problems and solve problems. Better maintenance and repair of magnetic separator equipment are an important prerequisite to properly use equipment and ensure the construction.
Q:Who know what kind of fire shutter fire rating are there?
There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd. Location: Xiangyang Xiangfan state Jianshe Road, Xiangzhou District, Xiangyang, Hubei Province
Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned brick whose cememting agent is phosphoric acid or aluminium phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
Q:Can anyone say something about what A-level fire-proof decorative material is?
The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
Q:What are fireproofing materials?
Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .
Q:What refractories can withstand high temperature above 2100 degrees?
Usually a dryer will not have such a high temperature. I do not know what you would use it for. Refractory cement coupled with quartz sand can work for 4 to 5 hours. So you can try cement coupled with corundum or superfine bauxite for better effect.
Q:How much refractory material is needed when 1 million ton coke oven is produced?
