Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013.

We export many kinds of coke, such as CSR64 % and CSR 62 metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.

We can offer below grade the NUT coke of 20 to 50 mm, origin from China.

Q: What does Coke test index M25 mean?: Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke)

Q: The chemical composition of coke is m10.m25: Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.

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 is the amount of waste gas produced by a ton of coke burning: Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent

Q: Listen to a lot of people say that steel is now coke is not true?: With the rapid development of the domestic and international iron and steel industry, the demand for coking products is increasing rapidly, the investment is heating up, and the industry is expanding rapidly. But the coking industry of high resource consumption, production and emissions, especially the emissions of harmful substances, causing serious waste of resources and environmental pollution, brings great pressure to the sustainable development of national economy, which also hindered the rapid development of coking industry.

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: Phosphorus is a kind of harmful element in metal, which reduces the mechanical properties of castings. Under normal circumstances, GB castings of phosphorus content requirements of less than 0.06%, the lower the special requirements

Q: In the coke analysis index, M40% and M25% respectively mean what?: M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%

Q: What's the difference between coke and coke?: In the process of coal carbonization of coal material: when the temperature is higher than 100 degrees in coal water evaporation; the temperature rises to 200 degrees above, combined with the release of water in coal; up to 350 DEG C, caking coal begin to soften, and further the formation of colloid viscous (this phenomenon does not occur, peat lignite; etc.) to 400 ~ 500 degrees most of the gas and tar precipitation, called a thermal decomposition products; at 450 to 550 DEG C, the thermal decomposition continues, gradually thickening and curing the formation of residue char!

Q: What is the difference between coke and coking coal: Coking coal is a kind of bituminous coal with a high degree of deterioration, and the thermal stability of the resultant colloid is good when the coke is produced separately. The block size of the coke is large, the crack is small and the strength is high

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!: Coke index:The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9
