1. Structure of The NUT Coke 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.

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: Coke can be used to do what carbon black can be used to do?
- 2 carbon black is produced by compounds of carbon and carbon, the main hydrocarbon combustion, the combustion is not sufficient, can not be converted into carbon dioxide, is carbon monoxide, so as small particles of carbon particles, which is carbon black; carbon black can be used as filling agent of rubber mixture, preferably for tires.
- 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: 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 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: Said the details can add points ah
- Visible: the two are called coke crushing strength index, has a certain correlation. Coking coking coal coke, the two general values are relatively large, and vice versa.The specific number of relations, to specific measurement of different manufacturers of coke M40 and M25 values, statistical regression, in order to determine.
- 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: With the number of 1 tons of steel smelting coke
- Because it can reduce energy consumption and reduce costs. So in the iron and steel enterprises coke rate decreased as the main goal of public relations, all the staff for the blast furnace coke rate reduction efforts. A few data in Liaoning, the average coke rate of Anshan and Benxi, Anshan Benxi is 330kg/t, is 360kg/t, that is to say a pig needs 330 360kg and coke production 2 saddle of the iron and steel enterprises. Shanghai Baosteel coke for the best in the country, can reach about 280kg/t. Is about 280kg per ton iron coke, the national leading level.
- 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: What are the quality indicators 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. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test. Evaluation of the quality of coke, 1 of sulfur in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%
- Q: The two day of the fire is not wang you have a good way to have any good way. Such online
- Take the gas stove ignition, and so it was burning 3, and then into the barbecue. Remember to add carbon, open the ventilation cover.
