1. Structure of The Metallurgical Coke of Size is 30 – 90 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 are the companies that produce coke
- Too many enterprises to produce coke. You search on Baidu, coke, a lot of business
- Q: Coke can be used to do what carbon black can be used to do?
- Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.
- Q: What chemical plant used to coke
- In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
- Q: Coking coal, coke, coal, steam coal what is the difference?
- Coking coal is the raw material for coke
- Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
- Yes；To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;
- 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?
- Types of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
- Q: What is the use of coke
- A definition of English Name: Coke, coke metallurgical coke blast furnace coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. 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: Natural gas can replace coke smelting pig iron
- Coke at high temperature (also some blast furnace pulverized coal, heavy oil, natural gas and other auxiliary fuel) in carbon with bubbling air oxygen in the combustion of carbon monoxide and hydrogen generated in the furnace, removing the rise in iron ore in the process of oxygen, thereby reducing iron. The molten iron is released from the taphole. An iron ore, which is a mixture of non - reducing impurities, such as limestone, to form a slag from the slag. The produced gas is discharged from the top of the furnace, and is used as a fuel for a hot blast stove, a heating furnace, a coke oven, a boiler, etc.. Blast furnace smelting is the main product of pig iron, as well as by-products of blast furnace slag and blast furnace gas.
- 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.
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- 4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.
