Q:What is coke? What is the use?
Lay the foundation for large-scale modern blast furnace, is an important milepost in the history of metallurgy. The blast furnace operation and achieve good technical and economic indexes, smelting with coke (coke) must have appropriate chemical and physical properties, including thermal properties in the smelting process.
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 the amount of waste gas produced by a ton of coke burning
The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)
Q: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.
Q:What is the effect of coke moisture on the blast furnace?
1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.
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:Why does Coke provide heat during ironmaking?
Yes;To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;
Q:Coke crushing equipment prices, manufacturers offer is how much
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)
Q:Purpose of using coke in iron making raw materials
Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron
Q:What's the connection between coking coal and coke
The coke can be obtained with the advantages of large grain size, few cracks and high crushing strength, and the abrasion resistance is good. But the expansion pressure, the coke pushing difficulties must be allocated to coal, lean coal, in order to improve the operating conditions and improve the quality of coke. Coking coal can play the role of coke skeleton and relieve shrinkage stress, so as to improve the mechanical strength of coke.
