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:Which kind of refractory floor is easy to use? ?: Fireproof wood floor includes three types, and according to your requirement, I think that the third type is more suitable or is easier to use. Here are the three types, and you can choose form them. A. Wear-resistant composite solid wood floor It is also known as super durable multi-layer solid wood floor. Its surface is inorganic glass fiber material and special paper impregnation thermosetting amino?resin, composited with solid wood base materials like plywood or core-board. And also, its front is wear-resistant layer while the back is balance layer, then hot press it into grooved and tongued floor. This is a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, comfort as solid wood floor, and stability as composite board. B. Fire-resistant wood-plastic composite decking board Wood-plastic composite decking board is not the wood floor in the traditional sense, but a composite material, also known as plastic wood. It is formed by high molecular improving and processing natural fiber, such as recycled plastic and wood fiber. It not only has the same advantages as plastic and wood, but alos has certain fire resistance, thus it is a environmentally friendly material with much development potential. C. Fireproof strengthened composite wood floor It is the so-called fireproof and fire retardant floor, fiber board, plywood and chipboard as its base materials. It is coated with fireproof coating and impregnated paper, and after fireproof and fire retardant technical process, it becomes a composite wood floor with some fire?retardant level. Its features are more partial to that of laminate floor with stable performance, steady structure and good durability.

Q:Who knows what is the standard of insulation material whose fire proof is level A?: Fire insulation materials of level A is non combustible building materials, and does not have any burning material. Level A1: single inorganic non combustible, no open flame. Level A2: A2 level: composite organic non combustible, that is, composite materials, non flammable, smoke volume should reach the standard.

Q:What are fire?ratings of wall thermal insulation material?: External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible?material, while grade B is combustible?material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincal records of production, provincal records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal?mortar produced by it is recommend product of Department of Construction in Hebei Province! Generally speaking, the combustion of phenolic aldehyde is grade B, but it can barely reach A2 when a thin layer of mortar is wiped outside.

Q:Can anyone tell me what is the material of which the mould for refractory is made？: Wooden mould will be used when refractories die is produced in small batch or composition of the refractory is complex. At the time of mass production, steel mould wil be used. The steel mould is a kind of imprint mold or cold mould. The cold mould, according to the working conditions of the products it manufactures, should have high hardness, strength, wear resistance, sufficient toughness and high hardenability. Commonly used steel types include high-carbon and low-alloy steel, high-carbon and high-chrome steel, chromium molybdenum steel and tungsten carbon chromium steel. You can choose them based on your needs

Q:What advantage and disadvantages it has compared to common fire insulation materials: Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.

Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: First of all, customer requirements, packaging according to customer requirements. According to the packaging packaging tray packaging is divided into 40 yuan / tons, carton 70 yuan / tons, 40 yuan / ton, straw packing bags of 30 yuan / ton.

Q:How to make fire resistant materials for building stoves: Grand Theft Auto Vice City plus life code is what?

Q:Where is refractory used? Thank you!: Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.

Q:I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!: Stable chemical properties. The crucible material should not be hydrolyzed at low temperature. It is difficult to be decomposed and reduced at high temperature and is not susceptible to corrosion by molten slag and molten metal;

Q:How to divided the grade of external wall thermal insulation materials?: Synthesized the 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 indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating test
