1. Structure of Metallurgical Coke of NUT coke of 10-30mm Description：
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
On June 3, in most domestic coke market and stable operation, individual regions have appeared downtrend, but declines gradually narrowed.By declines in the commodities market and the downstream steel demand remains sluggish performance, under the influence of the focal company of coke producer prices generally cut 10 to 30 yuan (tons of price, similarly hereinafter), leading to individual regions have with coke prices drop phenomenon, jiao qi said, but most of the region is low and coke coke prices are losing money, so the price will is not strong.After coke enterprises, according to the area where the price reduction, coking plant shipments did not have obvious improvement, the downstream steel receiving still light, lead to coking plant inventory increase slightly.Above all, expected short-term domestic coke market weak downward is given priority to, but not drop too much.

5. FAQ
Our country has experienced from rapid growth to coke production capacity to stabilize rebound, the process of China's coke production in 2010 of 388 million tons, up 9.10% from a year earlier, the proportion of total world production has rose from 20% in 1990 to 61.60% in 2010, is the world's first major producer of coke.
- Q: Which heroes know, please give the source of the data.
- From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
- 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 is the reasonable standard of volatile content of coke
- 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. 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 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.
- Q: What is the difference between coking coal and coke
- Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
- Q: How to remove the bottom of coke steel
- Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.After such a toss, the coke pot was removed, but the bottom layer of the so-called "nonstick layer" are often the early damage (normally always destroyed), it is impossible to. It's like trying to get rid of terrorists.If the bottom of the layer of carbon black is not easy to erase, even if, even with good. Some people may worry about eating into the carbon poisoning, I think there is no need to worry about this. Wenchuan earthquake hero, Mr. Zhu Jianqiang, light to eat charcoal for 36 days, you can see the toxicity of carbon nothing. Moreover, after cleaning the rice cooker in the layer of carbon black has very little
- 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
- Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
- Q: The coke is divided into several separate uses
- Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
- 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: 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%.
- 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.
