Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.Blast furnace with coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process.Coke in addition to a large number of used in ironmaking and smelting non-ferrous metal (metallurgical coke), also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different.If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low;Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point;Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.

- Q:What is the difference between coke and semi coke in ferrosilicon smelting process? In the process of energy statistics in the end should be 0.9714 of the conversion coefficient should be used with the conversion coefficient of 0.75 x 0.9714, please expert advice? emergencyUrgent!
- Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
- Q:What's the difference between coke and coke?
- When the dry distillation is carried out in the chamber type dry distillation furnace, the primary thermal decomposition product is contacted with the red hot coke and the high temperature furnace wall, and the two thermal decomposition occurs, and the thermal decomposition product (coke oven gas and other coking chemical products) is formed in the two timeThe solid product of low temperature distillation is a black semi coke with loose structure, low gas yield and high tar yield;The high temperature distillation solid product is the structure compact silver gray coke, the coal gas production rate is high and the tar production rate is low
- Q:What is the use of coke
- The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;
- Q:What is the density of coke?
- The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
- Q:What are the main uses of coke
- A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas. ??4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
- 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: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
- 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: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.
- Q:The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?
- The sulfur content of coking coal basically all into the coke, only a small number into the gas but the number is very limited. How much coal is the amount of sulfur in the general coal is the sulfur. It should be said that coke is basically a little lower and a little bit limited.In the process of coking volatile will be a lot of consumption, ash will increase 2-3%.
- Q:Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you
- Phosphorus increased the brittleness of cast iron, the use of metal damage. Therefore, the requirements of the foundry phosphorus is the lower the better. Because of the large cupola furnace in the furnace is acidic, can not effectively dephosphorization, so the foundry coke in the phosphorus requirements as low as possible, and require the supplier to provide a quality guarantee form.
