1. Structure of Metallurgical Coke of Met coke of CSR 58 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.
Price is the most important thing is to study the supply and demand.Supply and demand means under the condition of market economy, commodity supply and demand between the mutual connection and restriction relationship, it is the relationship between production and consumption in the market.When supply exceeds demand, the price fall, the opposite.Prices at the same time, in turn, will affect supply and demand, that is, when prices rise, the supply will increase and demand decrease, whereas will appear increasing demand and supply decrease, so the price and the mutual influence of supply and demand.

5. FAQ
Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.
- Q:Effect of coal fineness on coke
- The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
- Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- The use of coke:Shanxi sales of various specifications of foundry coke, metallurgical coke, high sulfur coke or motor transport cars can be. The specific indicators are as follows:More than 83 of the fixed carbon; sulfur below the volatile content of less than 1.5; ash around 15 e:Mechanism coke: used in metallurgy; steel plantFiddle coke size 8cm-150cm: of molten iron for casting {;} of motor shell, radiator, mechanical counterweightCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweightLarge modified coke: {for ordinary casting; mechanical parts such as rough parts for 2-3.5 tons of furnace type}The shape of coke size 25cm:{is used for ordinary casting and slightly rigid casting products, such as water pump pipe fittings, such as fire fastenerMore than 85 of the fixed carbon; volatile 1.5.; ash content of less than 13.5 sulfur; less than 0.5:A fiddle coke size above 8cm for ordinary casting: {}Setting coke size 25cm; {for precision casting and ductile castingImproved coke: (Jiao Meilian) {for precision casting and ductile castingCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweight
- Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
- There are also ISO and ASTM, I do not know what you want the standard?
- 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:F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
- Metallurgical coke indicators are as follows:A metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur;
- Q:How much coke is needed for a ton of iron
- 1 tons of iron: iron ore + + coke 340kg + pulverized coal injection 130kg,The process of extracting iron from iron containing minerals, mainly iron oxides, is mainly composed of blast furnace, direct reduction, smelting reduction and plasma method. From the perspective of ironmaking is metallurgy, iron rust, inverse behavior gradually mineralized, simple, pure iron reduction from iron compounds. Pure iron is not common in actual production. More iron carbon alloy.
- 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 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 does Coke test index M25 mean?
- 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
- Q:Coke indicators are divided into grades
- 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.
