1. Structure of Metallurgical Coke of Nut coke 15-30mm 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.
Also known as metallurgical coal, coking coal (coking coal) is medium and low volatile medium and strong adhesive bonding of a kind of bituminous coal.Coal classification in the national standard in China, is the high degree of coalification, coking of bituminous coal with good sex of appellation.Also known as the main coking coal.
On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ
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 ℃.
- Q: What does Coke test index M25 mean?
- The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 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; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance
- Q: Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?
- Dry carbon is not coke, but the combustion will produce a lot of harmful substances, it is recommended to install a more advanced cleaning device. Thank you
- Q: What is the reasonable standard of volatile content of coke
- The sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%.
- Q: What chemical plant used to 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
- Q: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
- Coal is the raw material that has not been treated by coking. Not every kind of coal for coke, according to the different requirements of the different kinds of coal
- Q: What is the amount of waste gas produced by a ton of coke burning
- Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent
- Q: Listen to a lot of people say that steel is now coke is not true?
- Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. In the steel-making pig iron sulfur content greater than 0.07% is waste. By blast furnace furnace into sulfur from 11% ore; 3.5% from limestone; 82.5% from coke, so coke is the main source of sulfur in charge coke. Sulfur directly affects the production of blast furnace coke. When the sulfur content is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the sulfur content of large and medium-sized metallurgical coke the blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the 0.02 - 0.03% or less
- 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: What are the national standards for grade two coke?
- Volatile content is not greater than 1.80; crushing strength: M40:76.1 - 80, M25:88.1 - 92; wear resistance: M10: not more than 8.5;
