Product Description:

1. Structure of Metallurgical Coke of COKE BREEZE OF 0 to 5mm Description:

Coke is usually divided into metallurgical coke according to the use (including blast furnace coke, coke and ferroalloy coke, etc.), gasification coke, calcium carbide with coke and so on.
By the coal pulverized coal pressure molding, post-processing is made by carbonization, etc formed new coke carbon called formed coke.

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.

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 mmcoke breeze of 3 to 6 mm, and so on.

Q:The difference between semi coke and coke
The difference between them is that the final temperature of the two, the use of different raw materials, product yield and product properties are not the same. Low temperature coke. Under the condition that the coal is isolated from the air, the product is heated to 500 to 600 DEG C to obtain the product. It uses the raw coal is lignite, metamorphic degree of coal, long flame coal and gas coal. The final purpose of the low temperature carbonization is to obtain high yield coal tar
Q:What is the difference between coke and carbon residue
Types of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
Q:What is the density of coke?
There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
Q:What are the main uses of coke
A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas.   4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
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:Why use coke instead of carbon in blast furnace ironmaking
The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
Q:What information is needed for coke export license
2013 coke export tariffs and quota system has been canceled, with foreign trade business qualifications can be engaged in foreign trade coke business. After signing the coke export contract with the foreign trade, the foreign trade enterprise needs to apply for the electronic key to apply for the export license. The electronic key and export license shall be handled as follows:
Q:The difference between coal and coke
The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.
Q:Natural gas can replace coke smelting pig iron
No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
Q:Mechanism of carbon and coke is not the same as the price which high?
I am on the Ba Chau facility in Hebei during May this year, but now has more than 3 months, only 2 tons of carbon, and are defective pile to nobody in my barn. I bought a big machine, according to them is made of bark can make the raw material drying, but home. It's not going to work. I had to switch to coal drying, coal can not over drying, rework is often the case. Carefully down a do tons of carbon coal money to spend more than and 300. The great machine can not work normally, the basic propeller around 4 hours repair time, until now I have changed my sleeve 7
