1. Structure of Metallurgical Coke of Met coke of CRI 28 Description：

Coke price from 1900 yuan in late January (tons of price, similarly hereinafter) fluctuation to the present stage of 1700 ~ 1800 yuan.However, coking coal prices is high.Shanxi linfen region level 9 coking coal prices as high as 1630 yuan of above.Earlier in the downstream steel industry affected by the energy conservation and emissions reduction, coke demand, coke prices are greatly influenced by steel prices.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ

Domestic coking enterprises generally adopt the limit production measures, hebei, shanxi and other places most of the coking plant in their production, limit production rate in 30% ~ 50%.

Q: Which heroes know, please give the source of the data.: You have to know what kind of coal isBituminous coal and anthracite are determined according to the content of volatile matter in coal,Bituminous coal has C content, geological time is long, but not easy to burn!It is also different from the different producing areas of bituminous coal. Mainly depends on what you want to be low calorific value (not including the vaporization of water vapor latent heat release). High calorific valueTo determine the coal species, industrial analysis, to determine the content of water, ash, volatile, fixed carbon content!That is, there is no formula, mainly the test.Low calorific value = high calorific value -206*H-23MH-- hydrogen contentM-- moisture content (both received base)

Q: Coke is how to make it? What is the use?: The production process has the following procedures:The preparation of coking coal is called coal preparation, which is prepared from various kinds of cleaned coal (or raw coal with low ash content), which is made up of coal, which has the advantages of high accuracy, good particle size, uniform quality and meeting the requirements of coking. Generally include: coal unloading, storage and mixing, mixing, crushing and mixing, and the preparation of coal to coke oven coal storage tower. In cold regions, there should be thawing and freezing equipment. To improve the quality of coke, we must pay enough attention to coal preparation. The coal blending is good, the accuracy of coal blending is improved, the fluctuation of coal quality is minimal, and the chemical composition and the physical mechanical property of the coke are ensured to stabilize the coke quality. Therefore, the coal blending equipment must be accurately according to the given value of coal blending; coal blending tank to be uniform continuous coal. In addition to the impurities in the coal, water can not be too high. The reasonable crushing of coal can effectively improve the mechanical strength of coke. According to the specific situation, the most suitable grinding particle size should be determined.

Q: The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?: Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,

Q: How much coke can a ton of coal: The key depends on volatile coking coal quality good volatile low words should now 1.3-1.4 tons of coking coal out of a ton of coke

Q: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.: Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active

Q: Why is coke used in blast furnace steelmaking?Why not use coal?: (2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.

Q: What is the use of coke: A definition of English Name: Coke, coke metallurgical coke blast furnace coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.

Q: I work in the coking plant, so there are conditions to get coke and is burning, I would like to use coke barbecue line? Just like charcoal Mutton Cubes Roasted on a Skewer, OK? Understand the answer: 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.

Q: What is the effect of coke moisture on the blast furnace?: 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa

Q: How to determine the maturity of coke or not?: The sulfur content of coke: refers to the percentage of sulfur content in coke. Sulfur is one of the harmful impurities in pig iron smelting. The sulfur content in the pig iron is more than 0.07%. 82.5% of the sulfur from blast furnace charge into the furnace comes from coke, so coke is the main source of sulfur. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased by 3.7%, with the increasing of the amount of ore 0.3%, blast furnace production decreased 1.5 - 2%.
