Product Description:

1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 Description

Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks.

To ensure the quality of coke, the choice is the most basic requirements of coking coal volatile matter, caking and coking properties; the vast majority of coking coal must go through washing, as much as possible to ensure low ash content, sulfur content and phosphorus content. When choosing a coking coal, but also must pay attention to the inflation pressure in the process of coal in coking. With low volatile coal coking, due to its colloid viscosity big, prone to high inflation pressure, harms the coke oven masonry, needs to be addressed by coal blending coking.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) Main type

Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

2) Application of coke

     Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury

     Other non-ferrous metal smelting of blast furnace,

     Reducing agent, compound

     The function of stock column frame.

3) The history of coke

Our country's metallurgical industry has a long history, is the original fuel charcoal smelting industry, due to the charcoal burning temperature is lower, and short duration of fire and not easy to master hour, therefore, directly affect the level of smelting, to make the steel quality is not guaranteed. Later, people use coal as smelting, coal combustion temperature is higher, and the combustion duration is longer than charcoal, but easily broken after coal is heated in the oven, affect the burden of permeability, and high content of sulfur in coal, directly affect the quality of the cast iron. After a period of practice, it has been found that the coal after dry distillation (i.e., separated flame heating), volatile components may be removed, and the porosity increased, resembling charcoal, fire is better than that of coal, but also can avoid charcoal and coal. This after carbonization of coal is coke.

Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.

Although the use of coke earliest in our country, but has not seen through the records. Coking and the earliest recorded with coke can be found in the late Ming dynasty in China side to write the physical knowledge, he pointed out that coal everywhere all have, "smelly burning-out and closed into stone, chisel and charging again yue reef (coke), May 5, fire, cook Fried mine stone, will save Labour". This smelly coal, it is to point to contain volatiles more coking coal, the coal sealed burning-out, becomes hard coke, used for smelting, the effect is very good.

Q:Purpose of using coke in iron making raw materials
It can capture the oxygen atoms in iron oxide or magnetic iron oxide to form carbon dioxide. The reaction equation is as follows:3C+2 (Fe2O3) = ==3 (CO2) +2Fe at high temperature2C+ (Fe3O4) = ==2 (CO2) +3Fe at high temperature
Q:Coke boiler belongs to coal-fired boiler
In addition, the utility model is characterized in that the utility model is used for heating and catering industry. Generally speaking, coke boiler belongs to coal fired boiler. Reason is that coke is a coal and fat coal for coke production.
Q:Coke crushing equipment prices, manufacturers offer is how much
It is a solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure.
Q:How much coal can a kilogram of coal weigh?
The ratio is about 1 to about 0.7, that is, about 1 kilograms of coking coal can produce a total of about 0.7 kg of coke
Q:What are the ingredients of coke
Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. 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:Coking coal, coke, coal, steam coal what is the difference?
Coking coal is the raw material for coke
Q:How much coke is needed for a ton of iron
Iron ore in blast furnace, mainly iron and oxygen compound. At high temperature, the carbon monoxide produced in the coke and the carbon dioxide in the injection and the carbon monoxide generated by the carbon capture the oxygen in the iron ore, which is called the reduction. The iron ore is used to produce pig iron by reduction reaction. The gangue in the iron ore, the ash in the coke and the spraying material and the flux of the limestone in the furnace are combined to generate the slag, and the slag is discharged from the taphole and the slag outlet respectively. The gas is derived from the top of the furnace, which is used as industrial gas after dust removal. Modern blast furnace can also use the top of the high pressure, with the export part of the gas power generation.
Q:In the coke analysis index, M40% and M25% respectively mean what?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
Q:How much coke can a ton of coal
But before the words to use 1.5 tons of coking coal to produce a total of 1 tons of coke
Q:Mechanism of carbon and coke is not the same as the price which high?
Stick out almost all with crack. And they say the yield of 180 kg / hour also is very different, not only the normal production hours when the output of 100 kilograms. I had also directed his blog to the thought, the personality is good. It seems that I really fooled. Later on the Internet listen to friends that they and Beijing Shouke, and sell equipment are a group of Shouke and powerful equipment are factory Hebei Ba Chau do, the technician will not help garbage shit escape love who are also the factory to help Hebei Ba Chau cultivated. It is the general black crow. The wolf escaped, and ventured into the mouth. I put my story and I just hope I don't have the same people cheated, Juyuan suzerain is the biggest liar. Equipment market is too dirty, the bone charcoal mechanism shall not ah!
