焦炭是高温干馏的固体产物，主要成分是碳，是具有裂纹和不规则的孔孢结构体（或孔孢多孔体）。裂纹的多少直接影响到焦炭的力度和抗碎强度，其指标一般以裂纹度（指单位体积焦炭内的裂纹长度的多少）来衡量。炼铁高炉采用焦炭代替木炭，为现代高炉的大型化奠定了基础，是冶金史上的一个重大里程碑。为使高炉操作达到较好的技术经济指标，冶炼用焦炭（冶金焦）必须具有适当的化学性质和物理性质，包括冶炼过程中的热态性质。焦炭除大量用于炼铁和有色金属冶炼（冶金焦）外，还用于铸造、化工、电石和铁合金，其质量要求有所不同。如铸造用焦，一般要求粒度大、气孔率低、固定碳高和硫分低；化工气化用焦，对强度要求不严，但要求反应性好，灰熔点较高；电石生产用焦要求尽量提高固定碳含量。
Coke is high temperature carbonization of solid products, main component is carbon, is a spore structure crack and irregular hole hole (or spore porous body). 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. 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. For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process. Coke in addition to a large number of used in ironmaking and smelting non-ferrous metal (metallurgical coke), also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different. If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low; Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point; Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.

1.衡量孔隙结构的指标主要用气孔率（指焦炭气孔体积占总体积的百分数）来表示，它影响到焦炭的反应性和强度。不同用途的焦炭，对气孔率指标要求不同，一般冶金焦气孔率要求在40～45%，铸造焦要求在35～40%，出口焦要求在30%左右。
2.焦炭裂纹度与气孔率的高低，与炼焦所用煤种有直接关系，如以气煤为主炼得的焦炭，裂纹多，气孔率高，强度低；而以焦煤作为基础煤炼得的焦炭裂纹少、气孔率低、强度高。
3.焦炭强度通常用抗碎强度和耐磨强度两个指标来表示。焦炭的抗碎强度是指焦炭能抵抗受外来冲击力而不沿结构的裂纹或缺陷处破碎的能力，用M40值表示；
4.焦炭的耐磨强度是指焦炭能抵抗外来摩檫力而不产生表面玻璃形成碎屑或粉末的能力，用M10值表示。焦炭的裂纹度影响其抗碎强度M40值，焦炭的孔孢结构影响耐磨强度M10值。M40和M10值的测定方法很多，我国多采用德国米贡转鼓试验的方法。
5.焦炭的灰分对高炉冶炼的影响是十分显著的。焦炭灰分增加1％，焦炭用量增加2—2.5％因此，焦炭灰分的降低是十分必要的。
6.根据焦炭的挥发分含量可判断焦炭成熟度。如挥发分大于1.5％，则表示生焦；挥发分小于 0.5—0.7％，则表示过火，一般成熟的冶金焦挥发分为1％左右。
7.焦炭中的水分； 水分波动会使焦炭计量不准，从而引起炉况波动。此外，焦炭水分提高会使M04偏高，M10偏低，给转鼓指标带来误差。
1. The main pore structure index are measured with porosity (coke pore volume percentage of the total volume), it affects the reactivity of coke and strength. Different USES of the coke, different requirements to porosity index, general metallurgical coke porosity requirements in 40 ~ 45%, coke demand in 35 ~ 40%, and export coke demand at around 30%.
2. Coke crack and porosity of high and low, have direct relations with the coal used in coking, such as coke is given priority to with development of refined, cracks, porosity is high, the intensity is low; And based on coking coal as a refined coal coke crack less, low porosity, high strength.
3. Coke strength usually use crushing strength and abrasion resistance strength represented two indicators. Coke crushing strength refers to the coke can resist by external impact and not along the structure crack or defect broken ability, expressed in M40 value;
4. 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 determination method of M10 value a lot of, our country many meters in Germany gong drum test method.
5. The influence of coke ash content of blast furnace smelting is very significant. Coke ash content increased by 1%, the coke rate increase 2-2.5%, therefore, lower coke ash content is very necessary.
6. According to the volatile content of coke coke maturity. Such as volatile matter is more than 1.5%, green said coke; Volatile is less than 0.5-0.7%, say, generally mature metallurgical coke volatilizes into 1%.
7. The moisture in coke; Moisture fluctuations can make coke measurement, which cause the furnace condition fluctuation. In addition, coke moisture increase will make M04 on the high side, low M10, bring error to drum index.

焦炭是一种固体燃料，质硬、多孔、发热量高、用煤高温干馏而成，多用于炼铁。焦炭通常按用途分为冶金焦（包括高炉焦、铸造焦和铁合金焦等）、气化焦和电石用焦等。主要用于高炉炼铁和用于铜、铅、锌、钛、锑、汞等有色金属的鼓风炉冶炼，起还原剂、发热剂和料柱骨架作用。还用于铸造、化工、电石和铁合金，其质量要求有所不同。如铸造用焦，一般要求粒度大、气孔率低、固定碳高和硫分低；化工气化用焦，对强度要求不严，但要求反应性好，灰熔点较高；电石生产用焦要求尽量提高固定碳含量。
