1. Structure of Metallurgical Coke of Coke Strength after Reactivity 64 Description：
Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks. Separate focal piece of micro cracks along, namely coke porous body, also known as coke. Focal body consists of porosity and the pore wall, hole wall is also called the coke quality, its main component is carbon and minerals. How much coke crack directly affect the size and crushing strength of coke. Focal piece of micro cracks and holes spore structure of coke and abrasive resistance and high temperature reaction performance of coke has a close relationship. Spore structure usually use stomata average pore size and pore size distribution, specific surface area and pore wall thickness parameter.

5. FAQ
We have organized several common questions for our clients，may help you sincerely：
1) 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.
2) Application of coke
• Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury
• Other non-ferrous metal smelting of blast furnace,
• Reducing agent, compound
• The function of stock column frame.
3) The history of coke
Our country's metallurgical industry has a long history, is the original fuel charcoal smelting industry, due to the charcoal burning temperature is lower, and short duration of fire and not easy to master hour, therefore, directly affect the level of smelting, to make the steel quality is not guaranteed. Later, people use coal as smelting, coal combustion temperature is higher, and the combustion duration is longer than charcoal, but easily broken after coal is heated in the oven, affect the burden of permeability, and high content of sulfur in coal, directly affect the quality of the cast iron. After a period of practice, it has been found that the coal after dry distillation (i.e., separated flame heating), volatile components may be removed, and the porosity increased, resembling charcoal, fire is better than that of coal, but also can avoid charcoal and coal. This after carbonization of coal is coke.
