1. Structure of Metallurgical Coke of The met coke of 40-100mm 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.
In order to ensure the coking coal resources of domestic demand, to carry out the national energy conservation and emissions reduction program, China has many policies to control of coke export, export enterprises enthusiasm obviously inadequate.2009 countries in two batch issued 11.91 million tons of coke quota, and 12.01 million tons of export quotas flat in 2008.In the current import under the condition of weak demand, coke quota is too enough.

5. FAQ
Brazil, India and other countries with the improving gradually form a complete set of coke production capacity, the more inclined to imports of coking coal from coking, dependency of China's coke has a tendency to gradually reduce.
- Q: Standard grade two grade coke standard
- 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%.
- 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 ______.
- There is no containing copper sulfate solution with tin. Because the copper iron can be displaced from the salt solution in their description, copper and iron;To sum up, we can know that C, Al, Cu, Fe four elements of the order of activity is Al > C > Fe > Cu;The answer is: Al > C > Fe > Cu.
- Q: How much coal can a kilogram of coal weigh?
- But now the coking industry will not only coke coke, but with coking coal, fat coal, gas coal and other coal mixed coking
- Q: What is the amount of waste gas produced by a ton of coke burning
- Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent
- Q: What is the essential difference between coal and coke?
- [coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
- Q: 8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.
- The structure of benzene and toluene is similar, and the molecular composition is different from that of a CH2 atom cluster, which is called homologous;(5) the number of chloro compounds in the hydrogen molecule is equal to the number of hydrogen atoms in different environments, and toluene has four kinds of hydrogen atoms in different environments: methyl group on the top, the benzene ring on the top of the 3 species, and so on, there are 4 kinds of chlorine compounds in toluene,
- 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: What does the M40% and M25% mean in the analysis of coke?
- M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
- Q: I work in the coking plant, so there are conditions to get coke and is burning, I would like to use coke barbecue line? Just like charcoal Mutton Cubes Roasted on a Skewer, OK? Understand the answer
- Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
- Q: How many degrees of coke ignition temperature can ignite coke
- Ignition temperature (450-650) in air;The main physical properties of coke are as follows:True density is 1.8-1.95g/cm3;Apparent density of 0.88-1.08g/ cm3;
