1. Structure of Metallurgical Coke of Met coke size of 30-80mm 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.
The influence of national policy on prices is obvious.With the development of energy conservation and emissions reduction work, the government shut down a lot of small coal mines, coal supply will still be tight, so prices will rise, prices rise inevitably promote coke prices.National import and export policy, especially the import and export tariff policy is by adjusting the commodity cost to control a commodity exports into the important means to balance the domestic supply and demand.In addition, the large-scale integration of the coal industry in Shanxi Province, the national adjustment of export tariff rates are pushing coke price factors.The provinces to speed up elimination coking behind capacity will be tight supplies.

5. FAQ
Analysis of coking coal supply and demand, to pay attention to the coke import and export situation in China.Due to the coke export prices and domestic price linkage, basically at the same time the quota also play a key role.
- Q: What is the density of coke?
- The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
- Q: Coke is how to produce, what is its purpose?
- 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. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.
- Q: Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?
- 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: Effect of coal fineness on coke
- In coking, the caking property is not good and the coke quality is reduced. Therefore, from the perspective of the uniformity of coal, coal fineness of some good. From the operation point of view, the greater the fineness of coal coal bulk density is lower, the production capacity of coke oven is low, into the coke oven, fine coal powder easily by gas is brought out, and easy blockage of ascending pipe, gas collector, affect the normal production of the coke oven, and the set of tar in the trachea increased, the effect of recovery operation. Therefore, from the production point of view, the fineness of coal should not be too large. Bulk coal in the top of the coke oven, coal crushing fineness of the general control in less than 3mm component in the range of 73~83%. Tamping coking, generally about 90%. In this range, the fineness of pulverized coal can meet the requirements of coke quality and coke oven operation. The small coal crushing will reduce the adhesion and the bulk density of coal, so as to reduce the coke quality.
- Q: Why is coke used in blast furnace steelmaking?Why not use coal?
- (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.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.
- Q: Listen to a lot of people say that steel is now coke is not true?
- Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.
- Q: How to remove the bottom of coke steel
- Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.After such a toss, the coke pot was removed, but the bottom layer of the so-called "nonstick layer" are often the early damage (normally always destroyed), it is impossible to. It's like trying to get rid of terrorists.If the bottom of the layer of carbon black is not easy to erase, even if, even with good. Some people may worry about eating into the carbon poisoning, I think there is no need to worry about this. Wenchuan earthquake hero, Mr. Zhu Jianqiang, light to eat charcoal for 36 days, you can see the toxicity of carbon nothing. Moreover, after cleaning the rice cooker in the layer of carbon black has very little
- Q: How long should it be to store coke in the open air
- The ground is flat, so it is convenient to transport.In addition, if it can be stored indoors, try not to open. For shelter.
- Q: What are the national standards for grade two coke?
- Two national standards for metallurgical coke: total sulfur: 0.61 - 0.80; ash: 12.01 - 13.50
