1. Structure of NUTCoke of Size is 20--40 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.

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: Various types of coal coke are the main test items
- If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
- Q: We would like to export a batch of coke, I would like to know what information is required for a permit
- 1, the Ministry of commerce website download and fill in the import and export license enterprise electronic key application form".2, fill in the application form, the "Registration Form for foreign trade dealers original and copy" or "foreign investment enterprise approval certificate original and copy" and "for the people of the Id original and photocopy" issued by the Department of foreign trade and economic cooperation when sending license, receiving approval.3, through the examination and approval, notify the enterprise payment. The examination and approval authorities will fax to Beijing materials guofuan e-commerce security certification of the company, making the electronic key by guofuan company, guofuan company will make a good electronic key, the installation and use of CD, invoice and electronic key receive confirmation etc. three express mail to the examining and approving authority for the examination and approval organ shall notify the enterprise.
- Q: The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?
- Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,
- Q: Coking coal, coke, coal, steam coal what is the difference?
- Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent
- Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?
- Coke:The utility model is mainly used for blast furnace ironmaking and smelting of blast furnace for non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc.. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
- Q: What is the difference between coking coal and coke
- Coking coal is an essential raw material for the production of coking coal, coking coal is one of the main uses of coke, coke is full of coking coal, coking coal is necessary for coke.
- Q: What is the amount of waste gas produced by a ton of coke burning
- Process for producing coke, coke oven gas and coking chemical products by thermal decomposition and coking.
- 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: The difference between coke and coal
- Coal is known as the black gold, the food industry, which is one of the main sources of energy used in the human world since eighteenth Century...
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- Quality index of cokeCoke is the solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index generally refers to the unit volume of the crack (crack number within the coke grain length). To measure the pore structure of the main indicators to measure with porosity (only coke pore volume accounted for percentage of the total volume) that it affects the coke reactivity and strength. The different uses of the coke porosity index for different requirements, the general metallurgical coke gas hole rate in 40 ~ 45%, foundry requirements in 35 ~ 40%, coke export requirements in 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 and coking coal as a base; Coke coal refining. Crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of two indicators. The coke crushing strength is that coke can resist foreign impact force without ability along cracks or defects at the broken table, shown by M40 wear; strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, M10 value and abrasion strength influence of coke pore structure. M40 and M10 were determined by lot. In China the migon drum test in Germany.
