1. Structure of Metallurgical Coke of Coke lumps25-80MM Description:

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame. 

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ


China is facing competition from the demand of the surrounding area.Given India's steel production in the next 10 years is expected to increase 2 times, to the demand for coking coal in Asia is likely to lead to increased competition, make long-term supply relatively tight.In fact, the shift to quarterly contract pricing system embodies the international suppliers for demand and prices expected.

Q:Coking coal, coke, coal, steam coal what is the difference?
Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal
Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant
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 amount of waste gas produced by a ton of coke burning
Process for producing coke, coke oven gas and coking chemical products by thermal decomposition and coking.
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:the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
Q:What is the use of petroleum coke
Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.
Q:What is the use of coke
The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;
Q:Who knows the proportion of pig iron and coke used in Cupola
There is doubt: the export rate is lower than the standard exception.4, blank blank processing: according to customer requirements of different direct sales, some need to continue processing after the sale, the ordinary rough machined after a blank rate of about more than 70%, about 30% (excluding scrap scrap), dryer enterprises after after machining yield is about 25% ~ 30% (including waste scrap and iron, basically use recycled material, material waste accounted for ratio of 30% ~ 40%). To 1.5M x 2M cylinder, for example, rough weight of about 5.8 tons ~ ~ 6 tons (standard cylinder, including the cylinder head) cylinder head rough weight of about 1.7 tons ~ ~ 1.8 tons, cylinder weight of about about 4.2 tons. After processing, the cylinder head weighs about 0.5 tons to 0.6 tons, accounting for the proportion of about 65% to 70% head (excluding scrap, scrap accounted for about 10%, blank cylinder head and iron) accounted for about 30% ~ 35% blank cylinder head, accounted for the proportion is about 40% recycled waste, scrap iron accounted for under foot material proportion 60%, enterprises can not return direct sales (currently, only production enterprises can use recycled scrap iron). Total iron blank ratio is about 15% ~ 18%.
Q:What are the main uses of coke
The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
Q:What's the difference between coke and coke?
In the process of coal carbonization of coal material: when the temperature is higher than 100 degrees in coal water evaporation; the temperature rises to 200 degrees above, combined with the release of water in coal; up to 350 DEG C, caking coal begin to soften, and further the formation of colloid viscous (this phenomenon does not occur, peat lignite; etc.) to 400 ~ 500 degrees most of the gas and tar precipitation, called a thermal decomposition products; at 450 to 550 DEG C, the thermal decomposition continues, gradually thickening and curing the formation of residue char!
