1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 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: Standard grade two grade coke standard
- 2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.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%.
- Q: What does Coke test index M25 mean?
- . 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, our method using migon drum test in Germany.
- Q: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
- Two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile < 1.9%; all 6% "0.7%" water; sulfur;
- Q: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
- Coal is the raw material that has not been treated by coking. Not every kind of coal for coke, according to the different requirements of the different kinds of coal
- 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?
- In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (3) column frame.The density of coke in blast furnace burden is the smallest, and the coke volume accounts for 35% ~ ~ ~ of the total volume of blast furnace burden. Coke is relatively strong, and in the tuyere area has always been to maintain the block, so it is the skeleton of the blast furnace column, from the loose material column, to ensure that the column has a good gas permeability of the role of the furnace is an important factor.
- Q: What is the essential difference between coal and coke?
- [coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
- 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?
- 80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.
- Q: The chemical composition of coke m10.m25 refers to?
- 1, coal washing ((M25 drum index) metallurgical coke crushing strength is (M10 drum index) metallurgical coke wear strength is reflected
- Q: The cost of iron ore and coke
- At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
