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.
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.

5. FAQ
We have organized several common questions for our clients,may help you sincerely:
1) What are coke's main physical properties?
on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.
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 ℃.
2) 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.
3)Main type
Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.
Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.
In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.
- Q: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
- 6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system
- Q: What is cokeWhat applications are, what is the fire of Malachite copper
- Coke is used for heating, and coke is also used as a reducing agent to process the iron ore, the oxide ore, the malachite is the copper oxide
- Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
- Yes;To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;
- Q: What is the essential difference between coal and coke?
- Coke]Coke is bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. 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: Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
- Shanlihong to paste potIf the bottom of the pot cooking, cooking paste, can put a few shanlihong put the pot, add a little cold water boil (not dry), paste pot bottom will soon get rid of.
- Q: What are the ingredients of coke
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.
- Q: The cost of iron ore and coke
- Per ton of iron ore 490 yuan / ton, the use of steel per ton coke of 500 kg, coke per ton of 1250 yuan / ton. You can calculate the proportion of these data
- Q: The coke is divided into several separate uses
- Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
- 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: The two day of the fire is not wang you have a good way to have any good way. Such online
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage.
