Calcined Bauxite for aluminate cement
1.Introduction
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there.By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns.

- Q: Various types of coal coke are the main test items
- The basic instrument of coal laboratory of these conventional indicators required are: calorimetry, sulfur detection apparatus, muffle furnace (Gao Wenlu), or when the microcomputer controller temperature controller, drying oven (oven), instrument, glial layer measuring instrument, the ash melting point determination of caking index, in addition to auxiliary equipment: crusher, pulverizer, electronic balance, vibration sieve machine, two points etc.. The above is the coal test indicators by Hebi Huanuo coal testing equipment factory to provide, I hope to help you.
- Q: Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers
- . It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace according to a certain proportion, batch and order
- Q: What are the main uses of coke
- The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
- Q: What is the difference between coking plant and coke plant
- Never heard of coke plant, coking plant is the production of coke products, there are other chemical products, it is estimated that you said the coke plant is the purchase of other people's desire to sell second-hand coke traders.
- Q: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
- Metallurgical coke indicators are as follows:A metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur;
- Q: With the number of 1 tons of steel smelting coke
- The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence
- Q: What are the requirements for the quality of coke in blast furnace smelting
- Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke.
- Q: The coke is divided into several separate uses
- Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
- Q: In the coke analysis index, M40% and M25% respectively mean what?
- (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)
- Q: How much coke is needed for a ton of iron
- Blast furnace production is continuous. A generation of blast furnace (from start-up to overhaul shutdown of generation) to continuous production of more than ten years. The production, from the top (usually roof is composed by Bell and hopper of modern blast furnace is the valve bell and bell less top) constant load of iron ore, coke, flux, from the lower part of blast furnace tuyere blowing hot air (1000 to 1300 degrees Celsius), sprayed into the oil, coal or natural gas.
