1. Structure of Nut Coke with Normal Phosphorous 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:Mechanism of carbon and coke is not the same as the price which high?
- Stick out almost all with crack. And they say the yield of 180 kg / hour also is very different, not only the normal production hours when the output of 100 kilograms. I had also directed his blog to the thought, the personality is good. It seems that I really fooled. Later on the Internet listen to friends that they and Beijing Shouke, and sell equipment are a group of Shouke and powerful equipment are factory Hebei Ba Chau do, the technician will not help garbage shit escape love who are also the factory to help Hebei Ba Chau cultivated. It is the general black crow. The wolf escaped, and ventured into the mouth. I put my story and I just hope I don't have the same people cheated, Juyuan suzerain is the biggest liar. Equipment market is too dirty, the bone charcoal mechanism shall not ah!
- 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:How much coal can a kilogram of coal weigh?
- This made the better quality of coke and coking coal can be saved!. if it is reality, and generally not numerical said a meal how much coke coking coal, coking coal is mixed because the values of various uncertain coal
- Q:The two day of the fire is not wang you have a good way to have any good way. Such online
- If you are at the barbecue, with the leaves, the leaves on the carbon below, with a stick carbon increase, the ignition, a side side to add some minor burns carbon. If the technology is good, probably a few minutes. If there is no dry leaves to replace paper.
- Q:Effect of coal fineness on coke
- The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
- Q:What is the use of coke
- From the distribution of coke production in China, the distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china. Three, the use of coke coke is mainly used in blast furnace ironmaking and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting furnace, reducing agent, heating agent and the role of the material column skeleton. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
- Q:Effect of coke powder ratio on the index
- Evaluation of coke quality1, coke: sulfur sulfur is a harmful impurity, pig iron smelting, which makes it one of the iron quality. In steel and iron sulfur content greater than 0.07%, is a waste. From the 11% blast furnace of sulfur ore; 3.5% limestone; 82.5% from coke, so coke is the main source of sulfur. The charge directly affects the coke into blast furnace of sulfur when the sulfur content of coke production. For more than 1.6%, 0.1% sulfur, each additional 1.8%, increase the amount of coke, an increase of 3.7%, ore blast volume added limestone to reduce the yield by 0.3%, sulfur content of 1.5 - 2% metallurgical coke requirements do not exceed 1% 0.7%., the sulfur content of metallurgical coke is less than - 0.4 large and medium sized blast furnace
- Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- Quality index of cokeCoke is the 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 generally refers to the unit volume of the crack (crack number within the coke grain length). To measure the pore structure of the main indicators to measure with porosity (only coke pore volume accounted for percentage of the total volume) that it affects the coke reactivity and strength. The different uses of the coke porosity index for different requirements, the general metallurgical coke gas hole rate in 40 ~ 45%, foundry requirements in 35 ~ 40%, coke export requirements in 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength and coking coal as a base; Coke coal refining. Crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of two indicators. The coke crushing strength is that coke can resist foreign impact force without ability along cracks or defects at the broken table, shown by M40 wear; strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, M10 value and abrasion strength influence of coke pore structure. M40 and M10 were determined by lot. In China the migon drum test in Germany.
- 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:What's the difference between coke and coke?
- Higher than 550 DEG C, semi coke continues to decompose, precipitation of the remaining volatiles (the main component is hydrogen), semi coke weight loss at the same time contraction, the formation of cracks; temperature above the temperature of 800 degrees, the volume of semi coke hardens to form porous coke!
