FAQ

Types of coke and use of coke
The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.s
What are the indicators of first grade coke and the two grade coke?
No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9s
Coking coal, coke, coal, steam coal what is the difference?
Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agents
What are the requirements for the quality of coke in blast furnace smelting
4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.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.s
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.s
What is the main purpose of the use of coke
(1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.s
Coke in the steelmaking process in the end is what
It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.s
How to determine the maturity of coke or not?
The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.s
