Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples

Quite a lot! You'd better look at the standard coal GB/T212-2008,

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 requirements for coke and other accounts?

Futures account opening process1, customers need to carry the original natural person identity card or temporary identity card (must be within the validity period), at least any one settlement bank (China bank, agricultural bank, industrial and commercial bank, construction bank, Bank of Communications) debit card or passbook, to the Futures Company branch or the securities business Department (IB) personally.2, the signing of the "futures trading risk statement", "futures brokerage contract", "bank transfer", "letter of credit" and other agreements, to provide the phone, contact address and postal code.

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:Coke is divided into several kinds of specifications ah

Use:Fixed carbon above 83; sulfur below 0.5; volatile below 1.5; about 15 ash coke for metallurgical e: mechanism: {; applied to steel coke particle size 8cm-150cm:{} with hot metal; for motor shell, radiator, mechanical counterweight cast char: {of} fertilizer for hot metal; coke bulk modified casting shell, radiator, electric}: {mechanical counterweight for ordinary casting furnace;} machinery parts and other parts suitable for roughly 2-3.5 tons of coke particle size for 25cm:{type common casting and casting products slightly strict; such as fire pump pipe fastener} fixed carbon above 85; volatile ash 13.5 1.5.; the following: 0.5; sulfur with coke particle size above 8cm for ordinary casting: {} 25cm {type coke particle size; for precision casting and ductile casting improved coke}:

Q:The two day of the fire is not wang you have a good way to have any good way. Such online

Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.

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:Standard grade two grade coke standard

Quality index of cokeCoke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). 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). 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. 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.

Q:Who knows the proportion of pig iron and coke used in Cupola

Raw material inputs: the main raw material for casting pig iron, scrap steel, manganese, etc.. Under normal circumstances after the melting of ordinary cast iron scrap iron and scrap steel ratio of 9:1 or so, the drying enterprises use pig iron and scrap ratio of about 6:4, according to the requirements of the product. Because pig iron and scrap carbon content is not the same, the higher the carbon content of pig iron is about 4 ~ 4.3, low carbon steel scrap, about 0.8.

Q:What are the quality indicators of coke

Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). 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).
