1. Structure of Metallurgical Coke of Met coke size of 40-100mm 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.

Q: Standard grade two grade coke standard: Evaluation of coke quality1, 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%. 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 how to make it? What is the use?: The production process has the following procedures:The preparation of coking coal is called coal preparation, which is prepared from various kinds of cleaned coal (or raw coal with low ash content), which is made up of coal, which has the advantages of high accuracy, good particle size, uniform quality and meeting the requirements of coking. Generally include: coal unloading, storage and mixing, mixing, crushing and mixing, and the preparation of coal to coke oven coal storage tower. In cold regions, there should be thawing and freezing equipment. To improve the quality of coke, we must pay enough attention to coal preparation. The coal blending is good, the accuracy of coal blending is improved, the fluctuation of coal quality is minimal, and the chemical composition and the physical mechanical property of the coke are ensured to stabilize the coke quality. Therefore, the coal blending equipment must be accurately according to the given value of coal blending; coal blending tank to be uniform continuous coal. In addition to the impurities in the coal, water can not be too high. The reasonable crushing of coal can effectively improve the mechanical strength of coke. According to the specific situation, the most suitable grinding particle size should be determined.

Q: How to calculate the average particle size of coke: Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.

Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?: Charcoal:1 metallurgical industryIn the past, the charcoal was used to smelt iron ore, and the pig iron was melted by charcoal and coke. The structure and mechanical properties were not the same even if the chemical composition was the same. The charcoal smelting pig iron generally has the fine grain structure, the casting is compact, does not have the crack the characteristic, the pig iron with the charcoal production contains the impurity is few, is suitable for the production high quality steel. Due to the reduction of charcoal, so in the metallurgical industry can be used to restore ore smelting metal.In the non-ferrous metal production, charcoal used for surface flux, non-ferrous metal melting, the surface flux in the molten metal surface protective layer, so that the separation of metals and gases, can reduce the loss of molten metal splash, and can reduce the melting material in gas saturation.A large amount of charcoal is also used to produce crystalline silicon, silicon used charcoal ash production should not contain too much carbon and head.

Q: How much coal can a kilogram of coal weigh?: This made the better quality of coke and coking coal can be saved!. if it is reality, and generally not numerical said a meal how much coke coking coal, coking coal is mixed because the values of various uncertain coal

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 is the use of coke: The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;

Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce: The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.

Q: In the coke analysis index, M40% and M25% respectively mean what?: (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)

Q: Effect of coke powder ratio on the index: 2, the phosphorus content of coke: iron metallurgical coke content should be 0.02 - 0.03%.3, coke ash: blast furnace coke ash effect is very significant. The amount of coke ash in coke increased by 1%, an increase of 2 - 2.5%., therefore, a decrease in coke ash is necessary4, coke volatile: according to the coke can be judged by the volatile content of volatile volatile is greater than 1.5%, then the coke; volatile less than 0.5 - 0.7%, which means that too much, generally mature volatile metallurgical coke to about 1%.5, coke moisture: moisture fluctuations should not be measured in coke, causing fluctuations in the furnace conditions. In addition, increased M04 coke moisture content high, low M10, the drum index error
