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:After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?
Soak in hot water for a few hours (or a day and night).Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.
Q:The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?
(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:I see that there are metallurgical coke and coke on the Internet, what is the difference between them (I hope to be able to say in detail) and a level of two points, how is this going on?.. Where is the quality of coke in China? Hunan good coke plant which? Although the problem is a little bit more, I hope that insiders can give some useful information. Extremely grateful.
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: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: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:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
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 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.
Q:We would like to export a batch of coke, I would like to know what information is required for a permit
Step 1: apply for an electronic key:The electronic key is equivalent to the enterprise identity authentication, after the application is similar to online banking U shield, the cost of 350 yuan. Including the physical Key ($150) and digital certificate price ($200), where Key is a one-time fee, digital certificates for the annual cost, valid for one year.
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
The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
Q:What is the density of coke?
Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.
