1. Structure of Coke Breeze of 0 ---- 10 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.
Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.
Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.
On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ
We have organized several common questions for our clients，may help you sincerely：
1) How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
2) What are coke's main physical properties?
on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.
The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)
Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);
Ignition temperature (air) is 450-650 ℃.
3) How about your company？
Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.
- Q: What are the companies that produce coke
- Very much, what kind of coke do you want, our company would like to buy coke particles
- Q: What is the difference between metallurgical coke and chemical coke
- Metallurgical coke, bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization).
- Q: How to calculate the average particle size of coke
- Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.
- 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: China's coke iron smelting began in what time?
- The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
- Q: The coke is divided into several separate uses
- Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
- Q: What are the quality indicators 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%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test. Evaluation of the quality of coke, 1 of sulfur in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%
- Q: What is the effect of coke moisture on the blast furnace?
- 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
- Q: What's the difference between coke and coke?
- In the process of coal carbonization of coal material: when the temperature is higher than 100 degrees in coal water evaporation; the temperature rises to 200 degrees above, combined with the release of water in coal; up to 350 DEG C, caking coal begin to soften, and further the formation of colloid viscous (this phenomenon does not occur, peat lignite; etc.) to 400 ~ 500 degrees most of the gas and tar precipitation, called a thermal decomposition products; at 450 to 550 DEG C, the thermal decomposition continues, gradually thickening and curing the formation of residue char!
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- The use of coke:Shanxi sales of various specifications of foundry coke, metallurgical coke, high sulfur coke or motor transport cars can be. The specific indicators are as follows:More than 83 of the fixed carbon; sulfur below the volatile content of less than 1.5; ash around 15 e:Mechanism coke: used in metallurgy; steel plantFiddle coke size 8cm-150cm: of molten iron for casting {;} of motor shell, radiator, mechanical counterweightCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweightLarge modified coke: {for ordinary casting; mechanical parts such as rough parts for 2-3.5 tons of furnace type}The shape of coke size 25cm:{is used for ordinary casting and slightly rigid casting products, such as water pump pipe fittings, such as fire fastenerMore than 85 of the fixed carbon; volatile 1.5.; ash content of less than 13.5 sulfur; less than 0.5:A fiddle coke size above 8cm for ordinary casting: {}Setting coke size 25cm; {for precision casting and ductile castingImproved coke: (Jiao Meilian) {for precision casting and ductile castingCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweight
