1. Structure of Met Coke of 40-100mm 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 is how to produce, what is its purpose?
- Natural coke. Coke can be obtained by high-temperature carbonization of coal:
- Q: What is the reasonable ratio of coal to coke
- Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material
- 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?
- After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:
- Q: How much coal can a kilogram of coal weigh?
- But now the coking industry will not only coke coke, but with coking coal, fat coal, gas coal and other coal mixed coking
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (2) reducing agent.The reduction of ore in blast furnace is accomplished by indirect reduction and direct reduction. The indirect reduction is about 400 degrees centigrade. The indirect reduction is rising gas CO reduction in ore, iron oxide from high iron gradually reduced low iron until the metal iron, while producing CO2:
- Q: The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?
- Of course, the sulfur content of coke is low. Coke quality requirements: two grade coke containing sulfur below 0.7%
- Q: What is the difference between coke and semi coke in ferrosilicon smelting process? In the process of energy statistics in the end should be 0.9714 of the conversion coefficient should be used with the conversion coefficient of 0.75 x 0.9714, please expert advice? emergencyUrgent!
- Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
- Q: Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?
- Coke is not used for blast furnace ironmakingThe use of blast furnace burden include iron ore (natural ore, sinter and pellets), solvent (limestone or dolomite), and coke, charge from top order batch into the furnace. Coke in the blast furnace ironmaking can be summarized as follows:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(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.
- Q: What is coke and how is coke classified?
- 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. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed gas producer with solid slag, as the raw material to produce CO and H2 gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block degree appropriate and uniform. The general requirements are as follows: >80% fixed carbon ash; 1250 degrees Celsius; volatile 84%, ash
- Q: What is the difference between coke and coking coal
- Coke: a solid fuel, hard, porous, high calorific value coal. High temperature carbonization made for ironmakingTypes 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.
