1. Structure of Metallurgical Coke of Coke Strength after Reactivity 10-30mm 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 is the difference between the industrial analysis of coke and the industrial analysis of coal samples
- Quite a lot! You'd better look at the standard coal GB/T212-2008,
- 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 is used for smelting iron alloy coke, and the coke is used in blast furnace and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, heating agent and columnar skeleton.
- Q:Coke indicators are divided into grades
- Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke).
- 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:Which heroes know, please give the source of the data.
- From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
- Q:Effect of coal fineness on coke
- From the point of view of the uniformity of coal material, the more finely pulverized coal. But if the coal fineness is small, because of the presence of a larger particle weakly caking coal and ash and coke cracks increased, the uniformity of deterioration. If the particle size of coal is not uniform, it is easy to produce segregation phenomenon in the transportation process, the grain size of different size will be gradually stratified by size. Due to the different coal hardness of the coal blending, large particles of coal is often a greater hardness of coal, so the segregation phenomenon, will make the different coal species gradually separated, so that the uniformity of coal deterioration.

- Q:How many degrees of coke ignition temperature can ignite coke
- Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g
- Q:Standard grade two grade coke standard
- Evaluation of coke quality1, sulfur content 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:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.
- Ethylene containing carbon carbon double bonds can react with bromine and bromine, and reaction of bleaching, b.:
