1. Structure of The NUT Coke of Size is 20 –- 40 mm 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.
Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.
Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)
Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);
Ignition temperature (air) is 450-650 ℃.
3) How about your company？
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 CSR60 % 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.
- Q:Mechanism of carbon and coke is not the same as the price which high?
- Stick out almost all with crack. And they say the yield of 180 kg / hour also is very different, not only the normal production hours when the output of 100 kilograms. I had also directed his blog to the thought, the personality is good. It seems that I really fooled. Later on the Internet listen to friends that they and Beijing Shouke, and sell equipment are a group of Shouke and powerful equipment are factory Hebei Ba Chau do, the technician will not help garbage shit escape love who are also the factory to help Hebei Ba Chau cultivated. It is the general black crow. The wolf escaped, and ventured into the mouth. I put my story and I just hope I don't have the same people cheated, Juyuan suzerain is the biggest liar. Equipment market is too dirty, the bone charcoal mechanism shall not ah!
- Q:Coke can be used to do what carbon black can be used to do?
- 1 coke is used to restore the iron ore, coal through pressure, isolated air and high temperature dry distillation, and the by-product of coal gas and coal tar is an important chemical products;
- Q:What is coke and how is coke classified?
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed gas producer with solid slag, as the raw material to produce CO and H2 gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block degree appropriate and uniform. The general requirements are as follows: >80% fixed carbon ash; 1250 degrees Celsius; volatile 84%, ash
- 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 coal is turned into coke in the coking chamber
- Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
- Q:What are the quality indicators 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. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test. Evaluation of the quality of coke, 1 of sulfur in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 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: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:How to distinguish the level of coke. What is metallurgical coke
- Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
- 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 strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
- Q:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- 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)
