1. Structure of Metallurgical Coke of Met Coke M40（80） 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.
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
The wear-resisting of coke strength refers to the coke can resist external friction without the ability to produce glass formation on the surface of particles or powder, said with M10 values.The crack degree of coke affect its crushing strength M40 value, coke M10 hole spore structure impact abrasion strength value.M40 and M10 value determination method are many, China USES German m gong drum test method.
- Q: What is the density of coke?
- There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
- 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: Various types of coal coke are the main test items
- The basic instrument of coal laboratory of these conventional indicators required are: calorimetry, sulfur detection apparatus, muffle furnace (Gao Wenlu), or when the microcomputer controller temperature controller, drying oven (oven), instrument, glial layer measuring instrument, the ash melting point determination of caking index, in addition to auxiliary equipment: crusher, pulverizer, electronic balance, vibration sieve machine, two points etc.. The above is the coal test indicators by Hebi Huanuo coal testing equipment factory to provide, I hope to help you.
- 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 ______.
- There is no containing copper sulfate solution with tin. Because the copper iron can be displaced from the salt solution in their description, copper and iron;To sum up, we can know that C, Al, Cu, Fe four elements of the order of activity is Al > C > Fe > Cu;The answer is: Al > C > Fe > Cu.
- Q: I see that there are metallurgical coke and coke on the Internet, what is the difference between them (I hope to be able to say in detail) and a level of two points, how is this going on?.. Where is the quality of coke in China? Hunan good coke plant which? Although the problem is a little bit more, I hope that insiders can give some useful information. Extremely grateful.
- The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
- Q: Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?
- The high sulfur content of nodular cast iron, the most significant impact on the casting is caused by poor balling,
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (2) reducing agent.The reduction of ore in blast furnace is accomplished by indirect reduction and direct reduction. The indirect reduction is about 400 degrees centigrade. The indirect reduction is rising gas CO reduction in ore, iron oxide from high iron gradually reduced low iron until the metal iron, while producing CO2:
- Q: How many degrees of coke ignition temperature can ignite coke
- The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;
- Q: What is the difference between coke and coking coal
- Coke: a solid fuel, hard, porous, high calorific value coal. High temperature carbonization made for ironmakingTypes 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.
- Q: How to determine the maturity of coke or not?
- The sulfur content of coke: refers to the percentage of sulfur content in coke. Sulfur is one of the harmful impurities in pig iron smelting. The sulfur content in the pig iron is more than 0.07%. 82.5% of the sulfur from blast furnace charge into the furnace comes from coke, so coke is the main source of sulfur. 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 by 3.7%, with the increasing of the amount of ore 0.3%, blast furnace production decreased 1.5 - 2%.
