1. Structure of Nut Coke with Low 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.
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) 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) 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: Standard grade two grade coke standard
- 2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.
- Q: What is the use of petroleum coke
- Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.
- Q: The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?
- At a standard atmospheric pressure, the boiling point is 100 DEG C, the temperature of the water rises to a temperature of 100 DEG C, and the temperature will not change,So the water temperature can be increased to 100;Answer: (1) the heat absorbed by water is 3.6 * 106J;(2) after absorbing heat, the temperature of the water will rise to about 100 degrees centigrade
- Q: Coke is divided into several kinds of specifications ah
- Use:Fixed carbon above 83; sulfur below 0.5; volatile below 1.5; about 15 ash coke for metallurgical e: mechanism: {; applied to steel coke particle size 8cm-150cm:{} with hot metal; for motor shell, radiator, mechanical counterweight cast char: {of} fertilizer for hot metal; coke bulk modified casting shell, radiator, electric}: {mechanical counterweight for ordinary casting furnace;} machinery parts and other parts suitable for roughly 2-3.5 tons of coke particle size for 25cm:{type common casting and casting products slightly strict; such as fire pump pipe fastener} fixed carbon above 85; volatile ash 13.5 1.5.; the following: 0.5; sulfur with coke particle size above 8cm for ordinary casting: {} 25cm {type coke particle size; for precision casting and ductile casting improved coke}:
- Q: What kind of coke is needed for smelting special steel
- It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace
- Q: What is the phosphorus content in coke
- Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
- Q: The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?
- Of course, the sulfur content of coke is low. Coke quality requirements: two grade coke containing sulfur below 0.7%
- Q: Purpose of using coke in iron making raw materials
- It can capture the oxygen atoms in iron oxide or magnetic iron oxide to form carbon dioxide. The reaction equation is as follows:3C+2 (Fe2O3) = ==3 (CO2) +2Fe at high temperature2C+ (Fe3O4) = ==2 (CO2) +3Fe at high temperature
- Q: The coke is divided into several separate uses
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.
- Q: I work in the coking plant, so there are conditions to get coke and is burning, I would like to use coke barbecue line? Just like charcoal Mutton Cubes Roasted on a Skewer, OK? Understand the answer
- 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.
