Product Description:

1. Structure of Metallurgical Coke of Met Coke M40(82) 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.

High temperature carbonization of solid products, main component is carbon, is to have cracks and not in September 1, 2009 - the national statistics of the coke production rules of hole spore structure spore porous body (or holes).Crack much directly affect the strength of coke and crushing strength, its index with crack degrees commonly (coke within the crack length per unit volume) to measure.Measure the main hole spore structure with porosity (only coke pore volume percentage of the total volume), it affects the reactivity of coke and strength

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

In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.

Q:How much coke can a ton of coal
But before the words to use 1.5 tons of coking coal to produce a total of 1 tons of coke
Q:Coke is divided into several kinds of specifications ah
(Lord Jiao Meilian) {for precision casting and ductile casting for} fixed carbon above 86; sulfur ash is below 0.5; 12; 1.5: volatile fiddle coke grain size 4cm--8cm or above 10cm: fixed carbon furnace for {}} setting common casting coke particle size 25cm:{for precision casting and ductile casting for 3 more than 88 tons of sulfur ash; 0.5; 10; 1.5: volatile foundry coke particle size 25cm:{type applicable to the above all high precision ductile casting export and international index: {8cm} fiddle coke for common casting and casting products such as strict fire pump fittings; fasteners such as high fixed carbon above 788385} sulfur: {for copper, aluminum, plastic, chemical coke} fixed carbon above 83 gas coal coke: {for carbon monoxide gas extraction, rich gas} fixed carbon about 78 coal coke: {casting parts annealing, Coke, coke, civilian chemical copper, aluminum, plastic} fixed carbon about 65 coke, coke coal: {civil casting parts of annealing, chemical 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 are the requirements for the quality of coke in blast furnace smelting
4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
Q:Purpose of using coke in iron making raw materials
It can capture the oxygen atoms in iron oxide or magnetic iron oxide to form carbon dioxide. The reaction equation is as follows:3C+2 (Fe2O3) = ==3 (CO2) +2Fe at high temperature2C+ (Fe3O4) = ==2 (CO2) +3Fe at high temperature
Q:Who can talk about the coke industry prospects?
But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
Q:Why use coke instead of carbon in blast furnace ironmaking
The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
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:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Orange to the bottom of the potCut a few slices of orange into the pot boil, stuffy night, second days will be turned over the paste paste, it is easy to clean up.7, the old telephone card, magnetic card washing paste potProblem Description: run out of phone cards, shopping cards, discount cards, VIP cards piled up, although there are people who love this kind of thing, but most people had no interest, so, or use it to do something. When cooking is paste pot, if made of hard coke fouling cleaning shovel, cause scratches with the wooden shovel, and difficult to completely remove the coke fouling. Why not let those old cards reflect the use value?Method of operation: with the card along the edge of the pot, and gradually remove the coke scale clean. Note that when you do not need to force too hard. If the card is made of hard plastic, can also be used to scrape the dirt on the gas stove.
Q:What are the national standards for grade two coke?
All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
