Q:Coke in the steelmaking process in the end is what
3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.
Q:What are the indicators of first grade coke and the two grade coke?
No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9
Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process
The answer is: Ca3 (PO4) 2+5C+3SiO2High temperature. 3CaSiO3+2P+5CO =; production of cement, brick or building materials such as;(3) R Si, Si and HCl reaction is the reaction of SiHCl3 with hydrogen, by the reaction of the hydrolysis of SiHCl3, IV, and the generation of hydrogen and oxygen in a certain range will explode, so it must be in contact with oxygen and anhydrous conditions,Therefore, the answer is: SiHCl3 hydrolysis, while the production of H2, mixed with O2 explosion, etc.;(4) methanol oxidation reaction, under acidic conditions, methanol in the cathode of carbon dioxide and hydrogen ions, CH3OH+H2O-6e-=CO2+6H+,The answer is: CH3OH+H2O-6e-=CO2+6H+;(5) the significance of this link in industrial production: recycling of raw materials, energy saving and emission reduction,The answer is: recycling of raw materials, energy-saving emission reduction;(6) from P to H3PO4, the phosphorus and oxygen into water and phosphorus pentoxide, compound phosphate, the equation is P+O2=P2O5, P2O5+3H2O=2H3PO4,The answer is: P+O2=P2O5; P2O5+3H2O=2H3PO4
Q:What are the main uses of coke
Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
Q:Coke is how to make it? What is the use?
Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.
Q:Coke coal charcoal are used for what
Manufacture of carburizing agentAll the requirements of the surface with high hardness and wear resistance, and the center has good toughness of all steel products to be carburizing. A carbonaceous mixture used for carburizing of steel products. Simple charcoal carburizing effect is poor. Therefore, commonly used charcoal as raw material, and then add a certain amount of contact agent, made of carburizing agent.
Q:Coke can be used to do what carbon black can be used to do?
2 carbon black is produced by compounds of carbon and carbon, the main hydrocarbon combustion, the combustion is not sufficient, can not be converted into carbon dioxide, is carbon monoxide, so as small particles of carbon particles, which is carbon black; carbon black can be used as filling agent of rubber mixture, preferably for tires.
Q:I'd like to have a coke
Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
Q:Coke is divided into several kinds of specifications ah
Use:Fixed carbon above 83; sulfur below 0.5; volatile below 1.5; about 15 ash coke for metallurgical e: mechanism: {; applied to steel coke particle size 8cm-150cm:{} with hot metal; for motor shell, radiator, mechanical counterweight cast char: {of} fertilizer for hot metal; coke bulk modified casting shell, radiator, electric}: {mechanical counterweight for ordinary casting furnace;} machinery parts and other parts suitable for roughly 2-3.5 tons of coke particle size for 25cm:{type common casting and casting products slightly strict; such as fire pump pipe fastener} fixed carbon above 85; volatile ash 13.5 1.5.; the following: 0.5; sulfur with coke particle size above 8cm for ordinary casting: {} 25cm {type coke particle size; for precision casting and ductile casting improved coke}:
Q:What is the use of coke
From the distribution of coke production in China, the distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china. Three, the use of coke coke is mainly used in blast furnace ironmaking and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting furnace, reducing agent, heating agent and the role of the material column skeleton. 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.
