- Q:I now do a good job in the coke network editor, I would like to know more about coke
- Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. In the process of blast furnace smelting, there are four kinds of functions, such as heat supply, reduction, material skeleton and carbon supply.
- 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
- The question is not clear, according to the words you say should be: coking tower = coke towerThat will not help you
- 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
- Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
- 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!
- Please see standard: metallurgical coke GB/T1996-2003, all clear
- Q:How to determine the maturity of coke or not?
- The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
- 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:Effect of coke powder ratio on the index
- Quality index of cokeHigh temperature carbonization coke is the solid product, its main ingredient is carbon, the pore structure of spores (or pore porous) with crack and irregular crack. Have a direct impact on how much strength and crushing strength of coke, the index of crack usually (crack length per unit volume of coke in the index) to measure indicator. Pore structure is mainly used for measuring the porosity of spores (pore volume percentage of the total volume of coke) said that it affects the reactivity and strength of coke. The coke used for different purposes, the porosity index requirements change, but it usually requires 40 to 45% metallurgical coke porosity, casting requirements of 35 to 40%, the export of coke need to crack about 30%. coke with high and low levels of porosity, the use of coking coal has a direct relationship, such as gas refining is mainly coke, crack, high porosity, low strength; as in coking coal Break the coke refining base of small, low porosity and high strength. The strength of coke is usually the crushing strength and abrasion resistance of two indexes to represent the strength of coke can be broken. No cracks or defects and M40 values along the fault reference external shock resistance structure; wear strength of coke coke refers to the ability to form glass the surface resistance to foreign friction and no fragments or powder, expressed as the value of M10. The degree of M40 crack coke compressive strength affect the value, value of pore structure of coke impact wear resistance of M10 spores. The determination of M40 M10 and a lot of value, many German migon drum test our method.
- Q:What does the M40% and M25% mean in the analysis of coke?
- (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
- Q:What's the difference between coke and coke?
- Higher than 550 DEG C, semi coke continues to decompose, precipitation of the remaining volatiles (the main component is hydrogen), semi coke weight loss at the same time contraction, the formation of cracks; temperature above the temperature of 800 degrees, the volume of semi coke hardens to form porous coke!
- Q:Coke is how to make it? What is the use?
- Coke production has prepared the material into the coal charging car from coal tower, were sent to the furnace chamber. The gas produced by the dry distillation is sent to the chemical product recovery workshop for processing. After a coking period (from charging to pushing the required time is generally 14 to 18 hours, depending on the carbonization chamber and the width), a pusher will mature by refining coke coke machine into the coke car; coke quenching, coke is discharged into the cold coke; then screening and storage (Figure 4).The coking plant is generally composed of two coke ovens. The two coke ovens are arranged on the same central line, and a coal tower is arranged in the middle. A furnace with coke oven machinery -- corresponding charging car and coke machine, machine coke, coke quenching car and motor vehicle; also equipped with a set of facilities including coke quenching, coke quenching tower, coke quenching pump, coke powder and coke powder sedimentation tank grab, arranged in the end furnace group. The center of the coke quenching tower is not less than 40 meters from the center of the carbonization chamber. If dry coke quenching, coke oven station. The coking plant is also equipped with the necessary piping and reversing system.
