1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 Description：
Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.
Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.
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.
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
Coke after coke strength after reaction is refers to the response under the action of thermal stress and mechanical force and resistance to fracture and wear ability.
- Q: What are the companies that produce coke
- Very much, what kind of coke do you want, our company would like to buy coke particles
- Q: The difference between coal and coke
- The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.
- Q: Various types of coal coke are the main test items
- If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
- Q: The chemical composition of coke is m10.m25
- Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.
- Q: Types of coke and use of coke
- The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.
- Q: Coking coal, coke, coal, steam coal what is the difference?
- Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal
- Q: Coke indicators are divided into grades
- 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. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength
- Q: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- 2, gasification coke, is dedicated to the production of coke gas, mainly used for solid slag in the fixed bed gas producer, as a gasification raw material, the production of CO and H2 as a combustible component of the gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block proper and uniform.
- Q: How to determine the maturity of coke or not?
- The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
- Q: How much coke is needed for a ton of iron
- Iron ore in blast furnace, mainly iron and oxygen compound. At high temperature, the carbon monoxide produced in the coke and the carbon dioxide in the injection and the carbon monoxide generated by the carbon capture the oxygen in the iron ore, which is called the reduction. The iron ore is used to produce pig iron by reduction reaction. The gangue in the iron ore, the ash in the coke and the spraying material and the flux of the limestone in the furnace are combined to generate the slag, and the slag is discharged from the taphole and the slag outlet respectively. The gas is derived from the top of the furnace, which is used as industrial gas after dust removal. Modern blast furnace can also use the top of the high pressure, with the export part of the gas power generation.
