Met coke 5-25mm 90% min

Iron ore species type is various, has found that the iron content of iron ore minerals and about 300 kinds, among the common there are more than 170 kinds.But in the current technical conditions, the main industrial utilization value is magnetic hematite, magnetite, hematite, ilmenite, limonite and siderite, etc.

Q: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you: 6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system

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: What is cokeWhat applications are, what is the fire of Malachite copper: Malachite is a kind of copper, copper smelting with coke burning malachite is under high temperature.

Q: Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant: Coking plant production capacity on the exclusion of the tower is also on the two: first, the coal tower; the two is coke bin;

Q: Effect of coal fineness on coke: From the point of view of the uniformity of coal material, the more finely pulverized coal. But if the coal fineness is small, because of the presence of a larger particle weakly caking coal and ash and coke cracks increased, the uniformity of deterioration. If the particle size of coal is not uniform, it is easy to produce segregation phenomenon in the transportation process, the grain size of different size will be gradually stratified by size. Due to the different coal hardness of the coal blending, large particles of coal is often a greater hardness of coal, so the segregation phenomenon, will make the different coal species gradually separated, so that the uniformity of coal deterioration.

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: What kind of coke is needed for smelting special steel: 3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.

Q: What is the use of coke: From the distribution of coke production in China, the distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china. Three, the use of coke coke is mainly used in blast furnace ironmaking and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting furnace, reducing agent, heating agent and the role of the material column skeleton. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

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: the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!: Thermal strength index: CSR CRIM40 M25 is the bigger the better, the smaller the better M10CSR the bigger the better the smaller the better CRISpecific standards to see the specific requirements of steel mills
