1. Structure of Metallurgical Coke of NUT coke of 20-40mm  Description:

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Hebei handan region, secondary metallurgical coke 1270 yuan now, quasi level 1 factory tax price of 1310 yuan, compared with yesterday fell 30 to 50 yuan.Tangshan secondary metallurgical coke 1360 yuan, the level of 1430 yuan.Secondary metallurgical coke in shanxi region is 1140-1160 yuan.East China mainstream secondary metallurgical coke d factory tax price 1290-1310 yuan.Northeast liaoning fushun area level of metallurgical coke factory tax price 1570 yuan;Heilongjiang qitaihe area secondary metallurgical coke factory tax price of 1430 yuan.Henan anyang region secondary metallurgical coke factory tax price 1340 yuan;Luoyang area secondary metallurgical coke factory tax price of 1550 yuan, with flat yesterday.

5. FAQ

As the global financial crisis, decline in coal prices significantly, and although domestic coal prices fell, but the price is still higher than the international coal market, this can make China's coal market supply and demand will further change.

Q: Which heroes know, please give the source of the data.
Each ton of refining coke can produce 430 cubic meters of gas, half melted combustion, the other half must be recovered with a special device, it can only be discharged directly into the air or "point sky lanterns
Q: What is the reasonable ratio of coal to coke
According to the proportion of each unit type, different operation, different existing coal and different coke quality requirements are different and so on, can be said to suggest that the landlord can look at the altar of the myriads of changes, in some aspects of the coal blending, grasp some general principles, and then develop the proportion according to the actual situation.
Q: Coke belongs to the coal industry
11 other mining industry 28 chemical fiber manufacturing 58 warehousing industryC manufacturing 29 rubber products 59 postal industry13 agricultural and sideline products processing industry 30 plastic products G information transmission, computer services and software industry31 grain grinding of non metallic products 60 telecommunications and other information transmission services 13101320 feed 311 cement, lime and gypsum manufacturing 601 Telecommunications133 vegetable oil 312 cement and gypsum products manufacturing 6020 Internet information1340 sugar 313 brick, stone and other building materials 603 broadcast television transmission135 slaughter and meat 314 glass and glass products 604 satellite transmission136 aquatic products 315 ceramic products 61 computer services
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: What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
Three, instrument and equipment of drying box: with automatic temperature adjusting device, can maintain the temperature of 170 DEG C and 105 a 180 a 110 C, the tray is made from galvanized sheet iron or aluminium sheet, size is about 300mm x 200mm X 20mm. The glass weighing bottles: diameter 40mm, high 25mm, and a grinding cover tightly. Dryer: inside the color of silica gel or granular anhydrous calcium chloride
Q: How coal is turned into coke in the coking chamber
Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
Q: What is the phosphorus content in coke
After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)
Q: Listen to a lot of people say that steel is now coke is not true?
Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke
Q: How many degrees of coke ignition temperature can ignite coke
The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;
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.
