1. Structure of The NUT Coke of Low Phosphorus 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.

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?
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: Types of coke and use of coke
- The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.
- Q: What are the main uses of coke
- The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
- Q: After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?
- Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.So that the whole place to restore the original black dye can be done.Water sandpaper rubbing can of course, but in the end to more than 1000 mesh water sandpapering. Another 100 clean cloth polishing line. The coke on the stove can only be removed by hand.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.
- Q: What is the difference between coking coal and coke
- Therefore, coke is not coking coal, coking coal is one of the products after processing
- Q: Coke indicators are divided into grades
- 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%. 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
- 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: I don't understand. With coke, then the rest of the coke, they are selling it?
- According to the use of coal can be divided into: injection coal, coal, coal coking coal can be divided into: lean coal, coking coal, gas coal, fat coal, lignite in five categories. Coking coal is used to refine coke. The power plant's coal coal power coal can also be said that under normal circumstances, can not be used for coking coal can be used to make electricity.
- Q: I see that there are metallurgical coke and coke on the Internet, what is the difference between them (I hope to be able to say in detail) and a level of two points, how is this going on?.. Where is the quality of coke in China? Hunan good coke plant which? Although the problem is a little bit more, I hope that insiders can give some useful information. Extremely grateful.
- 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: the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
- Please see standard: metallurgical coke GB/T1996-2003, all clear
