1. Structure of Metallurgical Coke of Met Coke M40（82） 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.
High temperature carbonization of solid products, main component is carbon, is to have cracks and not in September 1, 2009 - the national statistics of the coke production rules of hole spore structure spore porous body (or holes).Crack much directly affect the strength of coke and crushing strength, its index with crack degrees commonly (coke within the crack length per unit volume) to measure.Measure the main hole spore structure with porosity (only coke pore volume percentage of the total volume), it affects the reactivity of coke and strength
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:Why is coke used in blast furnace steelmaking?Why not use coal?
- The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
- Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- 4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.
- 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:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.
- Carbon containing ammonia, which belongs to the inorganic carbon monoxide; although contain carbon and inorganic nature but similar, belonging to the inorganic material, so the answer is: the 7;
- Q:What is the density of coke?
- Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.
- Q:What are the national standards for grade two coke?
- All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
- 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%.
- Q:How much coke is needed for a ton of iron
- Iron ore in blast furnace, mainly iron and oxygen compound. At high temperature, the carbon monoxide produced in the coke and the carbon dioxide in the injection and the carbon monoxide generated by the carbon capture the oxygen in the iron ore, which is called the reduction. The iron ore is used to produce pig iron by reduction reaction. The gangue in the iron ore, the ash in the coke and the spraying material and the flux of the limestone in the furnace are combined to generate the slag, and the slag is discharged from the taphole and the slag outlet respectively. The gas is derived from the top of the furnace, which is used as industrial gas after dust removal. Modern blast furnace can also use the top of the high pressure, with the export part of the gas power generation.
- Q:Types of coke and use of coke
- China's coking industry has been formed with conventional machine coke oven blast furnace ironmaking production of metallurgical coke, with heat recovery coke oven production machinery foundry and foundry
- 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
