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.

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: Which heroes know, please give the source of the data.
- From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
- Q: What does Coke test index M25 mean?
- Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. 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)
- Q: What are the indicators of first grade coke and the two grade coke?
- Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9
- Q: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- K, Ca, Na, C, Mg, Al is not able to use C, CO, H2 and so on to restore the preparation of metal, because these metals are very active, can be used to restore copper and iron ore, indicating that the reduction of strong;
- Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
- Gasification coke, which is used in the production of coal gas, is mainly used in the fixed bed gas producer with solid slag, as the raw material for gasification, producing CO and H2 as the combustible component:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJ
- Q: What's the connection between coking coal and coke
- The coke can be obtained with the advantages of large grain size, few cracks and high crushing strength, and the abrasion resistance is good. But the expansion pressure, the coke pushing difficulties must be allocated to coal, lean coal, in order to improve the operating conditions and improve the quality of coke. Coking coal can play the role of coke skeleton and relieve shrinkage stress, so as to improve the mechanical strength of coke.
- Q: What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
- There are also ISO and ASTM, I do not know what you want the standard?
- Q: What are the ingredients of coke
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.
- Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
- Q: What is the effect of coke moisture on the blast furnace?
- 1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.
