Q:How much coke is needed for a ton of iron
Blast furnace production is continuous. A generation of blast furnace (from start-up to overhaul shutdown of generation) to continuous production of more than ten years. The production, from the top (usually roof is composed by Bell and hopper of modern blast furnace is the valve bell and bell less top) constant load of iron ore, coke, flux, from the lower part of blast furnace tuyere blowing hot air (1000 to 1300 degrees Celsius), sprayed into the oil, coal or natural gas. Fuel
Q:What is the reasonable ratio of coal to coke
Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material
Q:Coke indicators are divided into grades
The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength
Q:What chemical plant used to coke
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:The chemical composition of coke is m10.m25
Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.
Q:What are the requirements for the quality of coke in blast furnace smelting
4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.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:The pulverized coal is separated from the air to enhance the heat, in addition to the main coke
Ethylene containing carbon carbon double bonds can react with bromine and bromine, and reaction of bleaching, b.:
Q:How much coal can a kilogram of coal weigh?
The ratio is about 1 to about 0.7, that is, about 1 kilograms of coking coal can produce a total of about 0.7 kg of coke
Q:The difference between coal and coke
Today, the Customs Tariff Commission of the State Council issued the notice on the implementation of the tariff plan in 2013. Shang magnesium network noticed,. This important change, apparently stems from the WTO requires China to cancel the export of raw materials restriction policy decisions. In recent years, due to higher export tariffs, coke exports almost stagnant, but also indirectly affect the production of magnesium metal. Due to insufficient supply of coke oven gas, and the price increases, the production of primary magnesium in the main producing area of Shanxi magnesium metal has been seriously reduced. Shang magnesium network analysis, the abolition of coke and semi coke export tariffs next year, the amount of exports should be theoretically faster recovery, some of the original magnesium production capacity will be restored. However, the government may take other measures to limit coke and semi coke production, coupled with the western economic downturn, exports may be rapid growth. Therefore, the coke industry after the abolition of export tariffs on the market situation remains to be seen, the impact on the magnesium industry has yet to be further assessed.
Q:What are the indicators of first grade coke and the two grade coke?
Two 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
