1. Structure of CNBM Met Coke ---- 30 - 90 mm 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.
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.

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
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: Which heroes know, please give the source of the data.
- From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
- Q: We would like to export a batch of coke, I would like to know what information is required for a permit
- Step 1: apply for an electronic key:The electronic key is equivalent to the enterprise identity authentication, after the application is similar to online banking U shield, the cost of 350 yuan. Including the physical Key ($150) and digital certificate price ($200), where Key is a one-time fee, digital certificates for the annual cost, valid for one year.
- Q: Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers
- . It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace according to a certain proportion, batch and order
- Q: What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
- 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: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- K, Ca, Na, C, Mg, Al is not able to use C, CO, H2 and so on to restore the preparation of metal, because these metals are very active, can be used to restore copper and iron ore, indicating that the reduction of strong;
- Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
- Gasification coke, which is used in the production of coal gas, is mainly used in the fixed bed gas producer with solid slag, as the raw material for gasification, producing CO and H2 as the combustible component:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJ
- Q: What is the essential difference between coal and coke?
- (1) power coal(2) coking coal (bituminous coal)(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
- Q: The cost of iron ore and coke
- The full cost of 2300 yuan / ton, manufacturing cost of 1950 yuan / ton, the use of iron ore per ton of steel 1.6 tons
- Q: Natural gas can replace coke smelting pig iron
- No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
- Q: What are the quality indicators of coke
- 2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%. 3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary. 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. Coke use: Shanxi sales all kinds of specifications of foundry coke, metallurgical coke, high sulfur coke trucks or wagons can transport
