As refractoriness
White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.
As abrasives
White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

- Q: How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q: Who knows what is the requirement for fireproofing of interior decoration materials ?
- In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: Who knows what kind of fire prevention materials are there?
- 1, Fire-proof board Fire-proof board is the most frequently used materials in the market. There are two kinds of fireproof boards which are commonly used; one is the high pressure decorative board, which has the advantages of fire prevention, damp proof, abrasion resistance, oil resistance, easy cleaning, and more variety of colors and designs. The other one is a glass magnesium fire board, the outer layer of which is a decorative material, the inner layer of which is a mineral glass magnesium fire material. It can resist 1500-degrees high temperature, but not suit for decoration. The installation of fireproof ceiling in the exit passageway, stair well and corridor can ensure safety evacuation, and protect people from the spread of the fire. 2 Fire-proof door Fireproof door is divided into wooden fire proof door, steel fire proof door and stainless steel fire proof door. Usually the fire proof door is used for the opening of the firewall, the entrance to the staircase, the evacuation of the aisle, the openings of the pipeline and other parts of the building, and it has an important role in fire separation and reducing the loss from fire. 2 Fire resisting shutter I hope it may be helpful to you.
- Q: What materials are needed to make the amorphous refractory bricks?
- I am so glad to answer your question. The amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive.
- Q: Does anyone knows which company produces the better refractory materials?
- I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
- Q: What are the specifications of refractory kilns ?
- Since the coefficient of thermal expansion of the basic brick is large, expansion rate is about 1-1.2% under 1000 ℃ The literature indicates that: "Under the condition that the temperature was raised to 1000 ℃ and stress in brick lining is relaxed, 300N / mm2 of compressive stress can be produced, which is equals to ten times structural strength of ordinary magnesia chrome brick, six times structural strength of magnesia chrome brick, dolomite brick and spinel brick, so any basic bricks can not afford, " the paper also pointed out that " heat expansion rate of kiln body can partially compensate for expansion rate of the inner lining of 0.2% -0.4%, which is 1/3 of thermal expansion rate of ordinary magnesia-chrome brick under 1000 ℃. However, it occurs under thermal equilibrium conditions. Thereby, the kiln should be dried slowly, allowing the temperature of the kiln body to go up slowly, thus the role of compensation can be played. " This is the key to using the basic brick. " Procedures of refractory for cement kiln "( tentative one) has clearly regulated baking and cooling of the kiln in the first section of the fifth chapters. In the heating process, in particular when the temperature is in the range of 300-1000 ℃, heating rate must be less than 60 ℃ / h. This is very clear in theory but it is difficult to implement.
- Q: Which refractory is better for building 1500 degree kiln ?
- High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
- Q: What is the the best ratio of mortar in refractory cement?
- The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
