- Q: What does Coke test index M25 mean?
- Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke)
- Q: Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilizationCa3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O (P), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilization rate is high, less waste(1) in the reaction, which belongs to the replacement reaction is ______[optional: (I), (II) and (III), (IV), (V).(2) chemical reaction equation II under high temperature of ______; solid waste can be used for ______. CaSiO3(3) reaction to be carried out in isolation and oxygen under anhydrous conditions, the reason is ______.(4) CH3OH can be used as a fuel cell fuel in strong acid medium, the electrode reaction type anode for ______.(5) pointed out that the significance of ______. (VI) in this part of the industrial production(6) written by P H3PO4, the reaction of the ______ ______.
- (1) according to the definition of replacement reaction, there are two kinds of compounds in the reaction of II, contains two kinds of compounds in the product, so it is not the replacement reaction of reactants, IV no elemental, so it is not a replacement reaction, V reaction is a chemical reaction, I and III reaction with replacement reaction conditions, so is the replacement reaction,
- Q: Coke indicators are divided into grades
- 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
- Q: What is the phosphorus content in coke
- Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
- Q: Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?
- 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 furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.
- 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
- The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
- Q: Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- It is a solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure.
- 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'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 are the criteria for coke classification and how to distinguish between primary and two grade coke?
- 4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.
