1. Structure of CSR 60% Metallurgical Coke Description：
Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks. Separate focal piece of micro cracks along, namely coke porous body, also known as coke. Focal body consists of porosity and the pore wall, hole wall is also called the coke quality, its main component is carbon and minerals. How much coke crack directly affect the size and crushing strength of coke. Focal piece of micro cracks and holes spore structure of coke and abrasive resistance and high temperature reaction performance of coke has a close relationship. Spore structure usually use stomata average pore size and pore size distribution, specific surface area and pore wall thickness parameter.

5. FAQ
We have organized several common questions for our clients，may help you sincerely：
1) 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.
2) Main type
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.
Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.
3) Application of coke
• Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury
• Other non-ferrous metal smelting of blast furnace,
• Reducing agent, compound
• The function of stock column frame.
- Q: What is the reasonable ratio of coal to coke
- There are lignite, bituminous coal, anthracite, semi anthracite these categories. Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage.
- 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 is the difference between coking plant and coke plant
- Never heard of coke plant, coking plant is the production of coke products, there are other chemical products, it is estimated that you said the coke plant is the purchase of other people's desire to sell second-hand coke traders.
- Q: Coke indicators are divided into grades
- 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
- Q: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
- From the heat, the quality of coke is generally greater than the quality of coal, such as coal, coal and the use of this kind of coal coke, coke prices higher.
- 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: What are the requirements for coke and other accounts?
- Coke futures margin is about 10% or so is quoted at $1169 per ton, trading units of 100 tons per hand, so do a coke about $11690.
- Q: What is the use of coke
- From the distribution of coke production in China, the distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china. Three, the use of coke coke is mainly used in blast furnace ironmaking and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting furnace, reducing agent, heating agent and the role of the material column skeleton. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
- 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
- As everyone knows, sulfur and phosphorus is harmful substances in the metal, because the sulfur is out in coke processing, so this index is not required, but the phosphorus in this process has not been effectively removed, so this is the requirement of foundry process or smelting plant. Phosphorus can reduce the strength of the metal, will lead to the metal "cold crisp", so to control the phosphorus content of coke, to prevent phosphorus into the metal.
- Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
