1. Structure of Metallurgical Coke of MET COKE SIZE OF 30-80MM Description:

Sulfur content in coke: sulfur is one of the harmful impurities of iron smelting, it lower the quality of cast iron.The sulfur content in pig iron for steel making is more than 0.07% for the trash.By the blast furnace burden into furnace sulfur 11% came from the ore;3.5% from limestone;82.5% from coke, so coke is the main source of sulfur in charge.Coke sulfur content directly affect the blast furnace ironmaking production.When coke sulfur content is greater than 1.6%, sulfur, every 0.1% increase in coke consumption increased by 1.8%, increased by 3.7%, for the amount of limestone ore content of 0.3% by 1.5 - a 0.3% increase in the blast furnace production. The sulfur content of metallurgical coke is not greater than 1%, large and medium blast furnace using the sulphur content in metallurgical coke is less than 0.4-0.7%.

5. FAQ

The coke of phosphorus points: metallurgical coke ironmaking use phosphorus content should be below 0.02-0.03%.

Q: Various types of coal coke are the main test items
Coal test items which specific indicators of coal test:Generally include coal test indicators include: calorific value of coal (calorific value), sulfur content (sulfur), ash, volatile, fixed carbon, char residue characteristics, total moisture, water analysis and other indicators
Q: Which heroes know, please give the source of the data.
You have to know what kind of coal isBituminous coal and anthracite are determined according to the content of volatile matter in coal,Bituminous coal has C content, geological time is long, but not easy to burn!It is also different from the different producing areas of bituminous coal. Mainly depends on what you want to be low calorific value (not including the vaporization of water vapor latent heat release). High calorific valueTo determine the coal species, industrial analysis, to determine the content of water, ash, volatile, fixed carbon content!That is, there is no formula, mainly the test.Low calorific value = high calorific value -206*H-23MH-- hydrogen contentM-- moisture content (both received base)
Q: What is the use of petroleum coke
Petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining
Q: Said the details can add points ah
Both are expressed in terms of the crushing strength of the cold mechanical strength index of coke quality.Among them, because of the specific measurement methods are not the same, so the use of different records.
Q: Effect of coal fineness on coke
From the point of view of the uniformity of coal material, the more finely pulverized coal. But if the coal fineness is small, because of the presence of a larger particle weakly caking coal and ash and coke cracks increased, the uniformity of deterioration. If the particle size of coal is not uniform, it is easy to produce segregation phenomenon in the transportation process, the grain size of different size will be gradually stratified by size. Due to the different coal hardness of the coal blending, large particles of coal is often a greater hardness of coal, so the segregation phenomenon, will make the different coal species gradually separated, so that the uniformity of coal deterioration.
Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?
Coke:The utility model is mainly used for blast furnace ironmaking and smelting of blast furnace for non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc.. 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: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
In terms of combustion, coal coke is a high pollution, therefore, coke pollution is less than coal. Coke smoke is very little, the smoke of coal is relatively large, there is also a high quality of soot rarely. When the coal is burning, the smell is bigger and the coke is not completely burnt, so the taste is small.
Q: How to distinguish the level of coke. What is metallurgical coke
The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke "
Q: How to remove the bottom of coke steel
So that the whole place to restore the original black dye can be done.Water sandpaper rubbing can of course, but in the end to more than 1000 mesh water sandpapering. Another 100 clean cloth polishing line. The coke on the stove can only be removed by hand.Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.
Q: What are the quality indicators of coke
Coke 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.
