Product Description:

Metallurgical coke is produced by carbonization of coals or coal blends at
temperatures up to 1400 K to produce a macroporous carbon material of
high strength and relatively large lump size.


Notes:
Metallurgical cokes must have a high strength to support heavy loads in
the blast furnace without disintegration. Metallurgical coke is also used as
filler coke for polygranular carbon products.

 

We have our own factory to supply all kind of metallurgical coke at good price.

If any need,pls contact us.

Q:What is the essential difference between coal and coke?
[coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
Q:The cost of iron ore and coke
At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press
Q:With the number of 1 tons of steel smelting coke
Because it can reduce energy consumption and reduce costs. So in the iron and steel enterprises coke rate decreased as the main goal of public relations, all the staff for the blast furnace coke rate reduction efforts. A few data in Liaoning, the average coke rate of Anshan and Benxi, Anshan Benxi is 330kg/t, is 360kg/t, that is to say a pig needs 330 360kg and coke production 2 saddle of the iron and steel enterprises. Shanghai Baosteel coke for the best in the country, can reach about 280kg/t. Is about 280kg per ton iron coke, the national leading level.
Q:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)
At a standard atmospheric pressure, the boiling point is 100 DEG C, the temperature of the water rises to a temperature of 100 DEG C, and the temperature will not change,So the water temperature can be increased to 100;Answer: (1) the heat absorbed by water is 3.6 * 106J;(2) after absorbing heat, the temperature of the water will rise to about 100 degrees centigrade
Q:Effect of coke powder ratio on the index
2, the phosphorus content of coke: iron metallurgical coke content should be 0.02 - 0.03%.3, coke ash: blast furnace coke ash effect is very significant. The amount of coke ash in coke increased by 1%, an increase of 2 - 2.5%., therefore, a decrease in coke ash is necessary4, coke volatile: according to the coke can be judged by the volatile content of volatile volatile is greater than 1.5%, then the coke; volatile less than 0.5 - 0.7%, which means that too much, generally mature volatile metallurgical coke to about 1%.5, coke moisture: moisture fluctuations should not be measured in coke, causing fluctuations in the furnace conditions. In addition, increased M04 coke moisture content high, low M10, the drum index error
Q:Sulphur content of coal and coke,
80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.
Q:I'd like to have a coke
Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
Q:What does Coke test index M25 mean?
. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10, our method using migon drum test in Germany.
Q:How to calculate the average particle size of coke
Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.
