Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
Coke GB/T 1996-2003, volatile coke is the most difficult to do
Q:Coking coal, coke, coal, steam coal what is the difference?
Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent
Q:What is the difference between coking plant and coke plant
Production equipment and production processes are complex.Coke plant, generally only the coal into coke on it, so simple.
Q:F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
Two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile < 1.9%; all 6% "0.7%" water; sulfur;
Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
3, calcium carbide coke is conductive body and a heating body for electric arc furnace of coke in the production of calcium carbide. Calcium carbide with coke into the electric arc furnace, arc heat and heat resistance at high temperature (1800-2200 degrees Celsius) under the action of complex reaction and lime, calcium carbide formation in the molten state (carbide). The generation process of the following reaction type available:CaO+3C - CaC2+CO-46.52KLCalcium carbide with coke should have low ash, high reactivity and high resistivity and grain size. The secondary characteristics, but also try to remove the powder and reduce moisture. Its chemical composition and particle size should meet the following requirement: >84% <14% fixed carbon, ash, volatile <2.0%, sulfur
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:Standard grade two grade coke standard
5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
Q:What is coke? What is the use?
In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. 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:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.
Carbon containing ammonia, which belongs to the inorganic carbon monoxide; although contain carbon and inorganic nature but similar, belonging to the inorganic material, so the answer is: the 7;
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 reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, 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!
