Product Description

Description of bauxite buyer

Description of bauxite buyer

There are several different models of raw bauxite,we own have three bauxite quarry,and can produce 5000 tons bauxite per month.

Classification of bauxite buyer

Classification of bauxite buyer

1.Refractory Grade:

1.Refractory Grade:

Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Bauxite in the refractory industry is typically used in ladle working lining, tundish furniture, delta sections, general perpose repairment, aluminium melting furnace and mineral processing.

3. Rotary calcined bauxite:

3. Rotary calcined bauxite:

Rotary Kiln Bauxite, as the name suggests, it is the bauxite produced by rotary kiln. there are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln.

4. Shaft kiln calcined bauxite:

4. Shaft kiln calcined bauxite:

Shaft kiln bauxite, the bauxite calcined by shaft kiln. the raw material-bauxite ore is loaded from the top of kiln together with coal powder and combustion improver,the fire of calcination comes from kiln bottom, about 1300-1400 ℃After the complete calcination, the bauxite is carried out from the bottom.

Q: How to divide fire rating of decorating materials ?: Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.

Q: What's the fireproof specification for constrcution external wall thermal insulation materials?: incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation?board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible?materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible?material (product); B1 nonflammable material (product); B2 combustible?material (product); B3 combustible material (product).

Q: Why the refractories should be waterproof and wetproof: It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use

Q: What is unshaped refractory?: Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.

Q: Who knows the fire resistant level of the rock wool color plate?: The rock wool color steel rock wool board is used in a area of high ??fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .

Q: How to make fire resistant materials for building stoves: Legend of the old version has been upgraded, or can not enter the server, is not legend stopped?

Q: How should refractory cement be used?: Types of refractory mortar Refractory mortar can be divided into the following types: casting of fire mortar: also known air setting fire mortar. It is used as a protective refractory layer in the kiln head burner, as a refractory material in some parts of preheater, and it is generally constructed by grouting. b: Insulation fire mortar: It is used to repair the deformed plane of the kiln shell, or for thermal insulation of the roof in the cooler. Refractory mortar: It is also known as thermosetting fire mortar, mainly used in brick masonary. When using, we must add the glassy water to stir. (silicic acid sodium, water, NaSiO3, H2O). General DiDOTECT 135 (having a heat resistance of above 1350 degrees Celsius) SK34 is used in the kiln tail. DiDOTECT 150 (having a heat resistance of above 1500 degrees Celsius). SK35 Couprit 160H is used under high temperature, and it is mainly used in the kiln head coal injection nozzle.

Q: What are the types of advanced refractory?: According to the chemical composition of minerals,refractory can be divided into eight categories: 1, siliceous material. 2, aluminosilicate materials. 3, magnesia materials. 4, dolomite materials. 5, chromium materials. 6, the carbonaceous material. 7, zirconium materials. 8, special refractories. 1. refractories according to chemical properties can be divided into three categories: 1, acidic refractory materials. 2, neutral refractories. 3, basic refractories. 1. refractories according to chemical properties can be divided into three categories: 1, ordinary refractories, refractoriness is 1580-1770 degrees. 2, advanced refractories refractoriness is 1770-2000 degrees. 3, super refractories refractoriness higher than 2000 degrees. 3. refractory according to the forming process can be classified into seven categories: 1, natural rock molding process. 2, compression moulding refractories. 3, moulding refractories by casting. 4, plastic molding refractories. 5, ramming molding refractories. 6, injection molding refractories. 7, extrusion molding refractories.
