1. Structure of Metallurgical Coke of 30-90mm 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.

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: What is the difference between metallurgical coke and chemical coke
- 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: Standard grade two grade coke standard
- 5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.

- (1) according to the definition of replacement reaction, there are two kinds of compounds in the reaction of II, contains two kinds of compounds in the product, so it is not the replacement reaction of reactants, IV no elemental, so it is not a replacement reaction, V reaction is a chemical reaction, I and III reaction with replacement reaction conditions, so is the replacement reaction,
- Q: After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?
- Soak in hot water for a few hours (or a day and night).Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.
- Q: What kind of coke is needed for smelting special steel
- 3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.
- Q: Listen to a lot of people say that steel is now coke is not true?
- But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
- Q: Coke and coal is one thing
- Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
- Q: How to remove the bottom of coke steel
- After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:Soak in hot water for a few hours (or a day and night).
- Q: What are the quality indicators of coke
- 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 fastener
- Q: What is the difference between coke and coking coal
- 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 coal gas producer with solid slag discharging. It is used as the raw material to produce CO and H2 gas
