1. Structure of Metallurgical Coke of COKE BREEZE of 3 - 6 MM Description：
Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.
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
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: Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers
- To be exact, you don't need coke for steelmaking, you say that it's iron making
- Q: What is the reasonable standard of volatile content of coke
- 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke 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 use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.
- Q: Coke is divided into several kinds of specifications ah
- (Lord Jiao Meilian) {for precision casting and ductile casting for} fixed carbon above 86; sulfur ash is below 0.5; 12; 1.5: volatile fiddle coke grain size 4cm--8cm or above 10cm: fixed carbon furnace for {}} setting common casting coke particle size 25cm:{for precision casting and ductile casting for 3 more than 88 tons of sulfur ash; 0.5; 10; 1.5: volatile foundry coke particle size 25cm:{type applicable to the above all high precision ductile casting export and international index: {8cm} fiddle coke for common casting and casting products such as strict fire pump fittings; fasteners such as high fixed carbon above 788385} sulfur: {for copper, aluminum, plastic, chemical coke} fixed carbon above 83 gas coal coke: {for carbon monoxide gas extraction, rich gas} fixed carbon about 78 coal coke: {casting parts annealing, Coke, coke, civilian chemical copper, aluminum, plastic} fixed carbon about 65 coke, coke coal: {civil casting parts of annealing, chemical coke}
- Q: What is the difference between coking plant and coke plant
- Production equipment and production processes are complex.Coke plant, generally only the coal into coke on it, so simple.
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.
- Q: What are the requirements for the quality of coke in blast furnace smelting
- 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. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
- Q: Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you
- Phosphorus increased the brittleness of cast iron, the use of metal damage. Therefore, the requirements of the foundry phosphorus is the lower the better. Because of the large cupola furnace in the furnace is acidic, can not effectively dephosphorization, so the foundry coke in the phosphorus requirements as low as possible, and require the supplier to provide a quality guarantee form.
- Q: Natural gas can replace coke smelting pig iron
- No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
- Q: What is the effect of coke moisture on the blast furnace?
- 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
- Q: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- Two, the type of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
