1. Structure of Metallurgical Coke of Coke Strength after Reactivity 64 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
- There are also ISO and ASTM, I do not know what you want the standard?
- 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:Coke is how to produce, what is its purpose?
- Natural coke. Coke can be obtained by high-temperature carbonization of coal:
- Q:The chemical composition of coke is m10.m25
- Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength
- Q:Various types of coal coke are the main test items
- If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
- 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 coke is divided into several separate uses
- Gasification coke is used for the production of coke gas. The utility model is mainly used in a fixed bed coal gas producer with solid slag discharging, and is used as a gasification raw material to produce CO and H2 as combustible components. The main reaction of gasification process:C+O2 - CO2+408177KJ
- Q:What does the M40% and M25% mean in the analysis of coke?
- (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
- 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:Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?
- The high sulfur content of nodular cast iron, the most significant impact on the casting is caused by poor balling,
