1. Structure of NUT Coke of Low Phos( 0.018% ) Description：
Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks.
Coke production of coking coal (coking coal), also known as metallurgical coal, belongs to the bituminous coal or sub-bituminous coal. Or use the various ratio of coal blend coking. Coking coal in the coke oven is isolated from oxygen after 1000 ° C carbonization is volatile component has been removing, the rest of the solid matter or coke. With the need of ironmaking as little as possible of sulphur, phosphorus pests, so should choose low sulfur, low phosphorus of coking coal.

5. FAQ
We have organized several common questions for our clients，may help you sincerely：
1) 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.
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
From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone. In China, the first kind of typical coal coking coal with hebei feng feng coal mine, shanxi gujiao cetrimonium, heilongjiang drops of jixi, anhui huaibei zhangzhuang and dabao top-coal panzhihua in sichuan province.The second category of typical coal coking coal have jilin tonghua iron works and the Inner Mongolia baotou beach ditch coal.Benxi, northeast China hebei tangshan, jingxing, shandong xinwen, etc., are all famous origin of coking coal.
- Q:Why is coke used in blast furnace steelmaking?Why not use coal?
- (2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.
- Q:Coke can be used to do what carbon black can be used to do?
- Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.
- Q:Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- K, Ca, Na, C, Mg, Al is not able to use C, CO, H2 and so on to restore the preparation of metal, because these metals are very active, can be used to restore copper and iron ore, indicating that the reduction of strong;
- Q:Coke boiler belongs to coal-fired boiler
- Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.
- Q:Coke is how to make it? What is the use?
- Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.
- 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:Coking coal, coke, coal, steam coal what is the difference?
- Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal
- 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 are the requirements for the quality of coke in blast furnace smelting
- 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%.5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
- Q:How to distinguish the level of coke. What is metallurgical coke
- Coke type: coke 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
