1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 Description：
Make 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.
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.
On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ
Coke physical properties including coke sieve grouped into truth, coke, coke powder density depending on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.
- Q: What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
- Methods for determination of moisture content of coke, a method of introduction of a certain quality of coke samples, placed in a drying box, drying at a certain temperature to a constant quality. Calculation of the percentage of water content in the mass loss of the coke sample. Two. Reagent color silica gel: industrial products
- Q: What is the difference between coking coal and coke
- Therefore, coke is not coking coal, coking coal is one of the products after processing
- Q: How coal is turned into coke in the coking chamber
- In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,
- 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: What is the amount of waste gas produced by a ton of coke burning
- The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)
- Q: What are the requirements for coke and other accounts?
- 4, I personally set the password and password.5, the customer I own the bank transfer agreement, my ID card, bank debit card to the corresponding bank outlets for bank transfer procedures.6, the day of the day to accept the phone call Futures Company visit, after the successful return of T+1 days of commodity futures trading.7, the customer into the gold (silver period transfer; non bank transfer).8, customer online transactions (start trading).
- Q: What is the use of coke
- Finally made coke, this process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis
- Q: What is the essential difference between coal and coke?
- Coke]Coke is bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.Coke 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: 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 the effect of coke moisture on the blast furnace?
- 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
