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: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:What kind of coke is needed for smelting special steel: It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace

Q:What does Coke test index M25 mean?: 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. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance

Q:Natural gas can replace coke smelting pig iron: Coke at high temperature (also some blast furnace pulverized coal, heavy oil, natural gas and other auxiliary fuel) in carbon with bubbling air oxygen in the combustion of carbon monoxide and hydrogen generated in the furnace, removing the rise in iron ore in the process of oxygen, thereby reducing iron. The molten iron is released from the taphole. An iron ore, which is a mixture of non - reducing impurities, such as limestone, to form a slag from the slag. The produced gas is discharged from the top of the furnace, and is used as a fuel for a hot blast stove, a heating furnace, a coke oven, a boiler, etc.. Blast furnace smelting is the main product of pig iron, as well as by-products of blast furnace slag and blast furnace gas.

Q:Coke boiler belongs to coal-fired boiler: They produce coke boiler to clean fuel production to reduce emissions as the main content.

Q:Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?: In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;

Q:What does the M40% and M25% mean in the analysis of coke?: (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.

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:Why is coke used in blast furnace steelmaking?Why not use coal?: (2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.
