1. Structure of Nut Coke with Low Phos 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.

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) 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.
Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.
Although the use of coke earliest in our country, but has not seen through the records. Coking and the earliest recorded with coke can be found in the late Ming dynasty in China side to write the physical knowledge, he pointed out that coal everywhere all have, "smelly burning-out and closed into stone, chisel and charging again yue reef (coke), May 5, fire, cook Fried mine stone, will save Labour". This smelly coal, it is to point to contain volatiles more coking coal, the coal sealed burning-out, becomes hard coke, used for smelting, the effect is very good.
