Product Description:

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:Method for removing coke from nonstick pan bottom
Soak in hot water for a few hours (or a day and night).Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.
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:Coking tower and coke tower is what relationship?
Coking plant production capacity on the exclusion of the tower is also on the two: first, the coal tower; the two is coke bin;
Q:What is the difference between coking coal and coke
Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
Q:What is coke and how is coke classified?
Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.
Q:I'd like to have a coke
Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on.
Q:What is the use of coke
Finally made coke, this process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis
Q:What is the density of coke?
There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
Q:Coke is how to make it? What is the use?
Coke production has prepared the material into the coal charging car from coal tower, were sent to the furnace chamber. The gas produced by the dry distillation is sent to the chemical product recovery workshop for processing. After a coking period (from charging to pushing the required time is generally 14 to 18 hours, depending on the carbonization chamber and the width), a pusher will mature by refining coke coke machine into the coke car; coke quenching, coke is discharged into the cold coke; then screening and storage (Figure 4).The coking plant is generally composed of two coke ovens. The two coke ovens are arranged on the same central line, and a coal tower is arranged in the middle. A furnace with coke oven machinery -- corresponding charging car and coke machine, machine coke, coke quenching car and motor vehicle; also equipped with a set of facilities including coke quenching, coke quenching tower, coke quenching pump, coke powder and coke powder sedimentation tank grab, arranged in the end furnace group. The center of the coke quenching tower is not less than 40 meters from the center of the carbonization chamber. If dry coke quenching, coke oven station. The coking plant is also equipped with the necessary piping and reversing system.
Q:What are the national standards for grade two coke?
All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
