Our company began to export coke when China cancelled 40% of coke export tariffsand quotas on January 1, 2013.

We export many kinds of coke, such as metallurgicalcoke (met coke) of 30-80mm, the NUT coke of 10 to 30 mm, coke breeze of 3 to 6 mm,and so on.

Q: What is cokeWhat applications are, what is the fire of Malachite copper: Malachite is a kind of copper, copper smelting with coke burning malachite is under high temperature.

Q: What is the reasonable ratio of coal to coke: There are lignite, bituminous coal, anthracite, semi anthracite these categories. 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: The chemical composition of coke is m10.m25: 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 is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.

Q: Listen to a lot of people say that steel is now coke is not true?: With the rapid development of the domestic and international iron and steel industry, the demand for coking products is increasing rapidly, the investment is heating up, and the industry is expanding rapidly. But the coking industry of high resource consumption, production and emissions, especially the emissions of harmful substances, causing serious waste of resources and environmental pollution, brings great pressure to the sustainable development of national economy, which also hindered the rapid development of coking industry.

Q: I now do a good job in the coke network editor, I would like to know more about coke: (3) column frame.The density of coke in blast furnace burden is the smallest, and the coke volume accounts for 35% ~ ~ ~ of the total volume of blast furnace burden. Coke is relatively strong, and in the tuyere area has always been to maintain the block, so it is the skeleton of the blast furnace column, from the loose material column, to ensure that the column has a good gas permeability of the role of the furnace is an important factor.

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: The cost of iron ore and coke: The full cost of 2300 yuan / ton, manufacturing cost of 1950 yuan / ton, the use of iron ore per ton of steel 1.6 tons

Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?: Quality index of cokeCoke is the solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index generally refers to the unit volume of the crack (crack number within the coke grain length). To measure the pore structure of the main indicators to measure with porosity (only coke pore volume accounted for percentage of the total volume) that it affects the coke reactivity and strength. The different uses of the coke porosity index for different requirements, the general metallurgical coke gas hole rate in 40 ~ 45%, foundry requirements in 35 ~ 40%, coke export requirements in 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 and coking coal as a base; Coke coal refining. Crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of two indicators. The coke crushing strength is that coke can resist foreign impact force without ability along cracks or defects at the broken table, shown by M40 wear; strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, M10 value and abrasion strength influence of coke pore structure. M40 and M10 were determined by lot. In China the migon drum test in Germany.

Q: How to determine the maturity of coke or not?: Ash in coke: the percentage of ash contained in metallurgical coke. The influence of coke ash on blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%. Therefore, it is necessary to reduce the ash content of coke.The volatile content in coke: refers to the percentage of the total amount of volatiles in metallurgical coke. Coke maturity can be judged according to the volatile content of coke. If the volatile content is greater than 1.5%, it is said that coke; volatile less than 0.5 - 0.7%, it is said to burn; generally mature metallurgical coke volatile is divided into about 1%.

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.
