1. Structure of Metallurgical Coke of Coke breeze 10-30mm 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.
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.
The report of inventory, also called "shadow inventory", refers to the global manufacturers, traders and consumers, hold inventory.Because the inventory not released regularly, so hard to count, typically measured in exchange of inventory.

5. FAQ
Consumption are the direct factors affect the price of coke, and with the development of coke industry is the important factors that affect consumption.The cost of production is the basis of the measure of commodity price level.
- 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: The chemical composition of coke is m10.m25
- Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.
- Q: With the number of 1 tons of steel smelting coke
- The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence
- Q: Coke and coal is one thing
- Coke is bituminous coal under the condition of isolated air, heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, solidification, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization).Coke is a deep processing of coal products.
- Q: Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you
- Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
- 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: Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%.
- 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;
- Q: What is coke and how is coke classified?
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed gas producer with solid slag, as the raw material to produce CO and H2 gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block degree appropriate and uniform. The general requirements are as follows: >80% fixed carbon ash; 1250 degrees Celsius; volatile 84%, ash
- Q: What is coke? What is the use?
- Lay the foundation for large-scale modern blast furnace, is an important milepost in the history of metallurgy. The blast furnace operation and achieve good technical and economic indexes, smelting with coke (coke) must have appropriate chemical and physical properties, including thermal properties in the smelting process.
