1. Structure of Metallurgical Coke of Met coke of 30 to 90 mm 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.
Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.

5. FAQ
Do you have warehouse?
Yes,we have.
- Q: The difference between coal and coke
- The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.
- 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 is the difference between coking plant and coke plant
- Production equipment and production processes are complex.Coke plant, generally only the coal into coke on it, so simple.
- 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: I don't understand. With coke, then the rest of the coke, they are selling it?
- According to the use of coal can be divided into: injection coal, coal, coal coking coal can be divided into: lean coal, coking coal, gas coal, fat coal, lignite in five categories. Coking coal is used to refine coke. The power plant's coal coal power coal can also be said that under normal circumstances, can not be used for coking coal can be used to make electricity.
- Q: The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?
- Of course, the sulfur content of coke is low. Coke quality requirements: two grade coke containing sulfur below 0.7%
- 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 are the ingredients of coke
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke.Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?
- Coke is not used for blast furnace ironmakingThe use of blast furnace burden include iron ore (natural ore, sinter and pellets), solvent (limestone or dolomite), and coke, charge from top order batch into the furnace. Coke in the blast furnace ironmaking can be summarized as follows:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
- Q: What are the national standards for grade two coke?
- Volatile content is not greater than 1.80; crushing strength: M40:76.1 - 80, M25:88.1 - 92; wear resistance: M10: not more than 8.5;
