Q: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 agent

Q:Coke indicators are divided into grades

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).

Q: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 1.9

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:Coke can be used to do what carbon black can be used to do?

Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.

Q:Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?

Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.

Q:Said the details can add points ah

Visible: the two are called coke crushing strength index, has a certain correlation. Coking coking coal coke, the two general values are relatively large, and vice versa.The specific number of relations, to specific measurement of different manufacturers of coke M40 and M25 values, statistical regression, in order to determine.

Q:Effect of coke powder ratio on the index

6, the size of coke in the blast furnace, coke screening is very important. We used the coke size requirements: large oven coke particle size greater than 40mm (1300--2000 square meters); small blast furnace coke particle size greater than 25 mm. But experiments show that some steel mills, coke size 40--25 mm good. More than 80mm of coke are screened to little change in the size range. This fragmentation of the coke uniform gap, small resistance furnace is running well.Purpose: various specifications of Shanxi foundry coke, metallurgical coke, coke car or high sulfur transport cars online sales. The specific indicators are as follows:Fixed carbon 83 or above; sulfur less than 0.5; 1.5 or less volatile; ash about E:Focal mechanism:Violin coke size 8 cm -150 cm:Metabituminous:Bulk modified coke:Size of 25 cm:

Q:China's coke iron smelting began in what time?

In the early period of the Warring States period, China has mastered the technology of decarbonization and heat treatment. The late Warring States period, but also invented a reusable "Iron Fan" (made of iron casting metal utensils of the hollow device). The Western Han Dynasty, appeared the crucible process. At the same time, the further expansion of the scale of shaft furnace. In 1975, in the vicinity of Zhengzhou guxing town discovered and unearthed Han iron smelting sites, site area of 120 thousand m2, two parallel excavated foundation of blast furnace, blast furnace volume of about 50m3

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.
