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 are the requirements for the quality of coke in blast furnace smelting
4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.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:What is the effect of coke moisture on the blast furnace?
2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
Q:It was concluded that the following two facts: coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore
Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
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. Fuel
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:The chemical composition of coke is m10.m25
Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.
Q:Why does casting coke require phosphorus?
As everyone knows, sulfur and phosphorus is harmful substances in the metal, because the sulfur is out in coke processing, so this index is not required, but the phosphorus in this process has not been effectively removed, so this is the requirement of foundry process or smelting plant. Phosphorus can reduce the strength of the metal, will lead to the metal "cold crisp", so to control the phosphorus content of coke, to prevent phosphorus into the metal.
Q:How coal is turned into coke in the coking chamber
In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,
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:How easy to use coke barbecue?
If you are at the barbecue, with the leaves, the leaves on the carbon below, with a stick carbon increase, the ignition, a side side to add some minor burns carbon. If the technology is good, probably a few minutes. If there is no dry leaves to replace paper.
