1. Structure of The NUT Coke of Size is 20 – 50 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.

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?
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: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
- Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press
- Q: What is the use of petroleum coke
- According to the quality can be divided into two kinds of primary and qualified products. Qualified products are divided into six grades. Used in the manufacture of electrodes, calcium carbide, corundum and so on and used as a filling tank, also used as insulating materials and fuel, etc..
- Q: How to calculate the average particle size of coke
- That is, "(volume) of the table of the percentage, in addition to the corresponding boundary value", these values are added, then the countdown. For example, the boundary 0 to 1 has a value of 10%, between 1 and 2, and between 2 and 4 has a value of 40%, and between 4 and 8, then D (3,2) = / (0.1/0.5 + 0.3/1.5 + 0.4/3 + 0.2/6) = 1/ (+ + 0.2 + + + 0.13 + +) = 1/0.56 = = =
- 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: Effect of coal fineness on coke
- From the point of view of the uniformity of coal material, the more finely pulverized coal. But if the coal fineness is small, because of the presence of a larger particle weakly caking coal and ash and coke cracks increased, the uniformity of deterioration. If the particle size of coal is not uniform, it is easy to produce segregation phenomenon in the transportation process, the grain size of different size will be gradually stratified by size. Due to the different coal hardness of the coal blending, large particles of coal is often a greater hardness of coal, so the segregation phenomenon, will make the different coal species gradually separated, so that the uniformity of coal deterioration.
- Q: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
- Metallurgical coke indicators are as follows:A metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur;
- Q: How much coke can a ton of coal
- The ratio is about 1 to 0.7, that is to say, 1 kilograms of about 0.7 kg coke coking coal coke, coke did not reach 0.75 kg, 0.71.Don't listen to them char 1.4:1, personal feeling.
- Q: Why is coke used in blast furnace steelmaking?Why not use coal?
- The role of coke in blast furnace steelmaking is as follows:(1) providing heat: the coke burns fiercely in the raceway in front of the tuyere of the coke oven, and the heat generated by the combustion is the main heat source in the process of blast furnace smelting.
- Q: What are the quality indicators of coke
- Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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.
