1. Structure of Metallurgical Coke of Met coke M40(80) Description:

As the domestic steel industry capacity utilization, domestic coking coal is expected to follow the international market prices rose significantly.Basic end of the current domestic steel industry destocking, as their production mechanism gradually withdraw from, since December, the domestic steel industry continue to production, according to our monitoring report, iron and steel industry capacity utilization has reached 85%.From the perspective of the year, 2011 of fixed assets investment growth 23% of judgment, crude steel production growth in 2011 will be 7% guaranteed.In the short term, the domestic steel production growth picks up, the international coking coal prices will drive domestic coking coal prices have relatively strong rising expectations.

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

In the past six months, as China's crude steel production growth is slowing, the region of crude steel production accounted for the proportion of global crude just production continues to decline, from other regions such as Europe and the United States steel consumption demand for support, international coking coal price mainly maintain at a high level (the fourth quarter of 209 dollars/ton).

Q:Who knows what the provisions of the coke train sampling country?
Methods for determination of moisture content of coke, a method of introduction of a certain quality of coke samples, placed in a drying box, drying at a certain temperature to a constant quality. Calculation of the percentage of water content in the mass loss of the coke sample. Two. Reagent color silica gel: industrial products
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: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: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:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Tomatoes to the bottom of the potNot a few good tomatoes in the pot boil, it will naturally fall.4, beer and liquor to the bottom of the potIf cooking is careful not to paste pot, the pot dish, if not easy to brush off, can pour a little wine and beer and a small amount of water (1:1:0.5 ratio) mixed cover, placed 5 minutes after it is easy to scrub clean.
Q:What are the main uses of coke
A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas.   4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
Q:Natural gas can replace coke smelting pig iron
No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
Q:What is the main purpose of the use of coke
(2) reducing agent.The reduction of ore in blast furnace is accomplished by indirect reduction and direct reduction. The indirect reduction is about 400 degrees centigrade. The indirect reduction is rising gas CO reduction in ore, iron oxide from high iron gradually reduced low iron until the metal iron, while producing CO2:
Q:Purpose of using coke in iron making raw materials
The coke can provide the heat required for the reaction and has the reducibility
Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
3, calcium carbide coke is conductive body and a heating body for electric arc furnace of coke in the production of calcium carbide. Calcium carbide with coke into the electric arc furnace, arc heat and heat resistance at high temperature (1800-2200 degrees Celsius) under the action of complex reaction and lime, calcium carbide formation in the molten state (carbide). The generation process of the following reaction type available:CaO+3C - CaC2+CO-46.52KLCalcium carbide with coke should have low ash, high reactivity and high resistivity and grain size. The secondary characteristics, but also try to remove the powder and reduce moisture. Its chemical composition and particle size should meet the following requirement: >84% <14% fixed carbon, ash, volatile <2.0%, sulfur
