1. Structure of the NUTCoke 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: What is the density of coke?
- The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
- Q: Coke belongs to the coal industry
- Classification and code (2002 Edition) code 25 petroleum processing, coking and nuclear fuel processing industry classification and code (2002 Edition) A agriculture, forest, animal husbandry and fishery 23 printing and record medium reproduction 4900 building decoration 01 24 agricultural stationery and sporting goods manufacturing 50 other building 02 forestry 25 oil processing and coking and nuclear fuel processing F transportation
- Q: Coke boiler belongs to coal-fired boiler
- Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.
- Q: What kind of coke is needed for smelting special steel
- What kind of coke smelting special steel need to ask the question itself is wrongThere are many kinds of special steel, different steel with different raw materials, the requirements of the quality of coke is not the sameSteel comes from iron, iron from iron ore and coke, and other additives
- Q: How to distinguish the level of coke. What is metallurgical coke
- Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
- 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: Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
- Tomatoes to the bottom of the potNot a few good tomatoes in the pot boil, it will naturally fall.4, beer and liquor to the bottom of the potIf cooking is careful not to paste pot, the pot dish, if not easy to brush off, can pour a little wine and beer and a small amount of water (1:1:0.5 ratio) mixed cover, placed 5 minutes after it is easy to scrub clean.
- Q: What are the requirements for the quality of coke in blast furnace smelting
- 4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
- Q: Purpose of using coke in iron making raw materials
- The coke can provide the heat required for the reaction and has the reducibility
- Q: Natural gas can replace coke smelting pig iron
- No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
