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: Standard grade two grade coke standard
5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
Q: How to calculate the average particle size of coke
Introduction of a commonly used, called "surface area volume average diameter", abbreviated D (3,2):D (3,2) = 1 / (fVI (/DI)).
Q: Coking coal, coke, coal, steam coal what is the difference?
Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent
Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?
Manufacture of carburizing agentAll the requirements of the surface with high hardness and wear resistance, and the center has good toughness of all steel products to be carburizing. A carbonaceous mixture used for carburizing of steel products. Simple charcoal carburizing effect is poor. Therefore, commonly used charcoal as raw material, and then add a certain amount of contact agent, made of carburizing agent.
Q: China's coke iron smelting began in what time?
The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
Q: Coke and coal is one thing
Coke is bituminous coal under the condition of isolated air, heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, solidification, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization).Coke is a deep processing of coal products.
Q: I now do a good job in the coke network editor, I would like to know more about coke
(1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.
Q: What are the ingredients of coke
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke.Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q: How many degrees of coke ignition temperature can ignite coke
Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g
Q: Mechanism of carbon and coke is not the same as the price which high?
Now, carbon factory has been discontinued, I start the original work - cable maintenance. The first floor of the post is my hair, said all no empty words. A combination of equipment quality is too bad, and Beijing Shougang, cleaning the equipment of large and the fact they are and exactly the same. Beijing is a liar equipment. Zhang Lian do is a donkey trading, factory equipment do Ba Chau are defective, they sold to Beijing fake technology company. I was at his factory inspection equipment of Shougang crooks in the factory. They stay trapped the loss of numerous investors. I now have been unable to recover
