INVERCOAL'S MET COKE

Q: What is the use of petroleum coke: Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.

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?: Yes；To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;

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.

Q: I don't understand. With coke, then the rest of the coke, they are selling it?: If most of the solid fuel is burning coal, but coking coal, which is very strong viscosity of coal is not good, it is very interesting to use the individual plant with it, the purpose is to change the fuel characteristics.Coking coal and coke, commonly used in metallurgical industry.Coal will be heated to a process of coke, but you really want to get coke, to specialized production. Power plants do not produce coke, they only have gray coke

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: 8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.: Carbon containing ammonia, which belongs to the inorganic carbon monoxide; although contain carbon and inorganic nature but similar, belonging to the inorganic material, so the answer is: the 7;

Q: What are the ingredients of coke: Two, coke distributionAccording to the distribution of coke production in China, the geographical distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china.Three, the use of cokeCoke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

Q: Purpose of using coke in iron making raw materials: The coke can provide the heat required for the reaction and has the reducibility

Q: The coke is divided into several separate uses: Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.

Q: What is coke? What is the use?: In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
