4.Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace. After a series of processing, it can become aluminium silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
7.Abrasives.
8.Ceramics industry.
9.Chemistry industry for all kinds of aluminium compound.

- Q: How much modulus is used as refractories material of sodium silicate.
- Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
- Q: Does the production of refractory belong to advanced technology？
- Refractories production is advanced technology supported by the state. The refractory enterprise is high-tech enterprises and it needs to apply for it in science and technology bureau.
- Q: Which are fire proofing thermal insulation materials?
- aluminum silicate fiber, ceramic fiber, etc,
- Q: What are the filling refractories in door leaf of class A fire resistant door?
- Perlite!
- Q: What are Grade-A waterproof inorganic thermal insulation materials?
- 1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.
- Q: what should be paid sttention when buying the refractory?
- First, look at the appearance of the product, it will be better if the surface of product is smooth, if there are the injuries and damages which may influence the use, do not use it. Second, the main characteristics of insulation material is flame resistance, reduce the loss of fire occurred at the time of purchase combustion performance testing products, non-combustible stone wool products are the best. Third, refractory insulation with good hygroscopicity is also very important, it can keep your room drying for a long time , played the role of moisture-proof, and more capillary, the hygroscopicity is better.
- Q: What are the requirements when producing fireproof materials by kaolin?
- Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
- Q: Do you know where I can buy refractories?
- You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
- Q: What are the specifications of refractory kilns ?
- There several points need to be noted ① selection of body material. The refractory lining of the front kilneye turns gelid and hot rapidly and frequently, so the temperature is in the range of 800 ℃ ~ 1250 ℃, allowing it to withstand wear of the cement clinker and corrosion of the cement base. The body material of castable refractory must be chosen according to its service conditions, in order to ensure that it is cheap and easy to use. ② the selection of admixture. Shapeless refractory materials are typical in-situ reaction refractories. Therefore choosing admixtures is very important and must ensure workability, baking performance, and excellent material properties. Admixture for Kiln refractory castable includes dispersants, accelerators, plasticizers, sintering agent, bulking agent and antidetonant. Materials of sintering agent are animate clay, zirconite, titanium dioxide and Peng compounds. Such substances produce a certain amount of mullite crystals, zircon phase, titanium aluminate crystal and inconsistent melting compounds (2Al2O3 ? B2O3), etc. under the operating temperature and in situ reaction. They are accompanied by volume expansion and microcracks, enabling it to compensate for the sintering shrinkage, so that the casting material can have sintering strength, corrosion resistance and good thermal shock resistance. In summary, the refractory castable material for the rotary kiln shall be determined in accordance with its service conditions. It is recommended that clients should also communicate with technical personnels and sales staff about some facts of the rotary kiln when buying it, so that they can get the satisfying rotary kiln.
