Product Description:

1. Structure of Metallurgical Coke of Coke nuts 10-30mm 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.

Chinese coal classification standard of coking coal is divided into two categories:
The first kind of coking coal volatile dry ash-free basis Vdaf = 10% ~ 28%, and the bonding index G > 65, glial layer thickness, y 25 mm or less.This part of the coal coking properties especially good, can separate out qualified blast furnace coke.
Another kind of coking coal volatile dry ash-free basis Vdaf = 20% ~ 28%, the bonding index G = 50 ~ 65, coking properties than the former.Coking coal with medium volatile and better bondability, is typical of coking coal, thermal stability can form good colloid when heated.Separate coking can get large blocks, crack of small, high crushing strength of coke, its wear resistance.But the inflation pressure make coke pushing hard, must match the gas coal, lean coal and so on, to improve the operating conditions and improve the quality of coke.In coking coal in coking coal can act as the skeleton and the effect of shrinkage stress relaxation, thus improve the coke mechanical strength, is the high quality coking raw materials.

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

From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone.

Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system
Q:Effect of coke powder ratio on the index
2, the phosphorus content of coke: iron metallurgical coke content should be 0.02 - 0.03%.3, coke ash: blast furnace coke ash effect is very significant. The amount of coke ash in coke increased by 1%, an increase of 2 - 2.5%., therefore, a decrease in coke ash is necessary4, coke volatile: according to the coke can be judged by the volatile content of volatile volatile is greater than 1.5%, then the coke; volatile less than 0.5 - 0.7%, which means that too much, generally mature volatile metallurgical coke to about 1%.5, coke moisture: moisture fluctuations should not be measured in coke, causing fluctuations in the furnace conditions. In addition, increased M04 coke moisture content high, low M10, the drum index error
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
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:What is the difference between coke and carbon residue
Types of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
Q:What does Coke test index M25 mean?
Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. 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:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)
(1) the amount of heat released from complete combustion of coke:Q put =mq=0.2kg * 3 * 107J/kg=6 * 106J.Heat absorbed by water:Q =Q * 106J suction ETA =6 * 60%=3.6 * 106J;(2) Q =cm t suction dreams,Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,
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:Coke is how to produce, what is its purpose?
Natural coke. Coke can be obtained by high-temperature carbonization of coal:
Q:Coke in the steelmaking process in the end is what
Coke is not used for blast furnace ironmakingThe use of blast furnace burden include iron ore (natural ore, sinter and pellets), solvent (limestone or dolomite), and coke, charge from top order batch into the furnace. Coke in the blast furnace ironmaking can be summarized as follows:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
Q:What is cokeWhat applications are, what is the fire of Malachite copper
Coke is used for heating, and coke is also used as a reducing agent to process the iron ore, the oxide ore, the malachite is the copper oxide
