1. Structure of Metallurgical Coke of Met coke of CRI 30 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%.
On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ
The coke of phosphorus points: metallurgical coke ironmaking use phosphorus content should be below 0.02-0.03%.
- Q: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
- Three metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6% "1%" water; sulfur;Maybe not, I'll give you a web site, find it yourself
- Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
- Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions
- Q: How to distinguish the level of coke. What is metallurgical coke
- Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
- Q: Why is coke used in blast furnace steelmaking?Why not use coal?
- The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
- Q: What's the connection between coking coal and coke
- Coke: the quality is hard and the hole is thick, the short hair will be wiped awayCoking coal is a kind of bituminous coal with medium caking property and strong caking property. The title of bituminous coal with high degree of coalification. Main coking coal.
- Q: I now do a good job in the coke network editor, I would like to know more about coke
- (2) reducing agent.The reduction of ore in blast furnace is accomplished by indirect reduction and direct reduction. The indirect reduction is about 400 degrees centigrade. The indirect reduction is rising gas CO reduction in ore, iron oxide from high iron gradually reduced low iron until the metal iron, while producing CO2:
- 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
- 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: Natural gas can replace coke smelting pig iron
- No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
- 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.
