1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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: The difference between coal and coke: The semi coke production tend to low temperature carbonization, distillation temperature at 600 degrees Celsius, due to a late start, at present the low temperature carbonization furnace single furnace annual output of 30 thousand tons / year in most equipment under low temperature carbonization furnace forum of more than 50 thousand tons / year scale is still at the exploratory and experimental stage, technology of the large-scale equipment is still not mature, can only achieve centralized mass production using a combination of multi furnace technology. The use of coal field is quite widespread, especially in the carbonaceous reducing agent has unique properties, economic advantages are very obvious.

Q: What does Coke test index M25 mean?: The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength 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

Q: How to calculate the average particle size of coke: Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.

Q: What are the indicators of first grade coke and the two grade coke?: Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9

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: 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: Why is coke used in blast furnace steelmaking?Why not use coal?: The role of coke in blast furnace steelmaking is as follows:(1) providing heat: the coke burns fiercely in the raceway in front of the tuyere of the coke oven, and the heat generated by the combustion is the main heat source in the process of blast furnace smelting.

Q: Coke and coal is one thing: Coke is bituminous coal under the condition of isolated air, heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, solidification, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization).Coke is a deep processing of coal products.

Q: What are the ingredients of coke: Two, coke distributionAccording to the distribution of coke production in China, the geographical distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china.Three, the use of cokeCoke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. 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.
