Q:It was concluded that the following two facts: coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore
Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
Q:What information is needed for coke export license
2013 coke export tariffs and quota system has been canceled, with foreign trade business qualifications can be engaged in foreign trade coke business. After signing the coke export contract with the foreign trade, the foreign trade enterprise needs to apply for the electronic key to apply for the export license. The electronic key and export license shall be handled as follows:
Q:Effect of coke powder ratio on the index
Quality index of cokeHigh temperature carbonization coke is the solid product, its main ingredient is carbon, the pore structure of spores (or pore porous) with crack and irregular crack. Have a direct impact on how much strength and crushing strength of coke, the index of crack usually (crack length per unit volume of coke in the index) to measure indicator. Pore structure is mainly used for measuring the porosity of spores (pore volume percentage of the total volume of coke) said that it affects the reactivity and strength of coke. The coke used for different purposes, the porosity index requirements change, but it usually requires 40 to 45% metallurgical coke porosity, casting requirements of 35 to 40%, the export of coke need to crack about 30%. coke with high and low levels of porosity, the use of coking coal has a direct relationship, such as gas refining is mainly coke, crack, high porosity, low strength; as in coking coal Break the coke refining base of small, low porosity and high strength. The strength of coke is usually the crushing strength and abrasion resistance of two indexes to represent the strength of coke can be broken. No cracks or defects and M40 values along the fault reference external shock resistance structure; wear strength of coke coke refers to the ability to form glass the surface resistance to foreign friction and no fragments or powder, expressed as the value of M10. The degree of M40 crack coke compressive strength affect the value, value of pore structure of coke impact wear resistance of M10 spores. The determination of M40 M10 and a lot of value, many German migon drum test our method.
Q:What is coke? What is the use?
In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. 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:Dry or dry carbon carbon, coke or coke, and I do not know which word of
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke.
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.

Q:What is the difference between coking coal and coke
Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
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.
Q:How to determine the maturity of coke or not?
The sulfur content of coke: refers to the percentage of sulfur content in coke. Sulfur is one of the harmful impurities in pig iron smelting. The sulfur content in the pig iron is more than 0.07%. 82.5% of the sulfur from blast furnace charge into the furnace comes from coke, so coke is the main source of sulfur. 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 by 3.7%, with the increasing of the amount of ore 0.3%, blast furnace production decreased 1.5 - 2%.
