Product Description

   Metallurgical coke is produced by carbonization of coals or coal blends at temperatures up to 1400K to produce a macroporous carbon material of high strength and relatively large lump size.It is mainly used in metallurgical and chemical industries. The coke in a cupola functions not only as a fuel but also as a medium of heat transfer. The key factor affecting the efficiency of the molten metal heating-up is the surface combustion temperature of the coke. Thus, the reactivity of the coke is important because it is closely related to the efficiency of the molten metal heating-up. Coke is primarily used to smelt iron ore and other bearing materials in blast furnaces, acting both as a source of heat and as a chemical reducing agent to produce iron or hot metal.

Met Coke is a kind of main raw materials used for steel makers, we have own coke plants at Shanxi province .

The coke handled by our cooperation is made from superior coking coal of Shanxi province. Provided with the advantages of low ash, low sulphur and high carbon. Our coke is well sold in European, American, Japanese and South-east Asian markets. Our owned Coke plant are located in Shanxi Province and supplying of you many kinds of coke. 

 

Product Uses

 

Main purpose: It is widely used in iron and non-ferrous metal smelting, casting, chemical industry, calcium carbide and ferroalloy, etc.

Q:With the number of 1 tons of steel smelting coke
The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence
Q:China's coke iron smelting began in what time?
The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
Q:What is the difference between metallurgical coke and chemical coke
Metallurgical coke, bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization).
Q:Types of coke and use of coke
China's coking industry has been formed with conventional machine coke oven blast furnace ironmaking production of metallurgical coke, with heat recovery coke oven production machinery foundry and foundry
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: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 chemical plant used to coke
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:What is the main purpose of the use of coke
Direct reduction in the blast furnace in the area above 850 degrees celsius. Because the CO2 generated at high temperature immediately reacts with the carbon in coke to form CO, it can be considered that the carbon in coke is directly involved in the reduction process:CO is used as reducing agent, either indirect or direct reduction. In order to continue to add CO, requires a certain degree of reactivity of coke.
Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
Quite a lot! You'd better look at the standard coal GB/T212-2008,
Q:Who knows the proportion of pig iron and coke used in Cupola
There are doubts: blank parts output is too low.3, blank export rate: raw materials into melting after the formation of blank, under normal circumstances, the common casting investment for every 1 tons of pig iron, scrap steel and other major raw materials, the lowest to 85% iron, after casting output blanks, nozzle, nozzle, riser, riser for iron smelting water ratio of about 30%; blank standard export rate, nozzle, riser re melted continue after put into use; production enterprises invested 1 tons per dryer, iron scrap and other major raw materials to the lowest 85% of the hot metal, roughly the same with ordinary casting, casting blank after the (standard yield) for hot metal ratio is about 70%, water riser for hot metal ratio is about 15%, and the same outlet riser re melted after continued use.
