1. Structure of NUT Coke of the size is 20 ----50 mm Description：
Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks. Separate focal piece of micro cracks along, namely coke porous body, also known as coke. Focal body consists of porosity and the pore wall, hole wall is also called the coke quality, its main component is carbon and minerals. How much coke crack directly affect the size and crushing strength of coke. Focal piece of micro cracks and holes spore structure of coke and abrasive resistance and high temperature reaction performance of coke has a close relationship. Spore structure usually use stomata average pore size and pore size distribution, specific surface area and pore wall thickness parameter.

• Other non-ferrous metal smelting of blast furnace,
• Reducing agent, compound
• The function of stock column frame.
- Q:The difference between coal and coke
- Today, the Customs Tariff Commission of the State Council issued the notice on the implementation of the tariff plan in 2013. Shang magnesium network noticed,. This important change, apparently stems from the WTO requires China to cancel the export of raw materials restriction policy decisions. In recent years, due to higher export tariffs, coke exports almost stagnant, but also indirectly affect the production of magnesium metal. Due to insufficient supply of coke oven gas, and the price increases, the production of primary magnesium in the main producing area of Shanxi magnesium metal has been seriously reduced. Shang magnesium network analysis, the abolition of coke and semi coke export tariffs next year, the amount of exports should be theoretically faster recovery, some of the original magnesium production capacity will be restored. However, the government may take other measures to limit coke and semi coke production, coupled with the western economic downturn, exports may be rapid growth. Therefore, the coke industry after the abolition of export tariffs on the market situation remains to be seen, the impact on the magnesium industry has yet to be further assessed.
- Q:How long should it be to store coke in the open air
- And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.
- Q:Effect of coal fineness on coke
- In coking, the caking property is not good and the coke quality is reduced. Therefore, from the perspective of the uniformity of coal, coal fineness of some good. From the operation point of view, the greater the fineness of coal coal bulk density is lower, the production capacity of coke oven is low, into the coke oven, fine coal powder easily by gas is brought out, and easy blockage of ascending pipe, gas collector, affect the normal production of the coke oven, and the set of tar in the trachea increased, the effect of recovery operation. Therefore, from the production point of view, the fineness of coal should not be too large. Bulk coal in the top of the coke oven, coal crushing fineness of the general control in less than 3mm component in the range of 73~83%. Tamping coking, generally about 90%. In this range, the fineness of pulverized coal can meet the requirements of coke quality and coke oven operation. The small coal crushing will reduce the adhesion and the bulk density of coal, so as to reduce the coke quality.
- 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.
- Ethylene containing carbon carbon double bond can add poly to generate polyvinyl chloride, can be used for food packaging, reaction equation is: nCH2=CH2Initiator,The answer is: nCH2=CH2Initiator;
- Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
- Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press
- Q:What is the density of coke?
- The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
- Q:The difference between coke and coal
- Coal is known as the black gold, the food industry, which is one of the main sources of energy used in the human world since eighteenth Century...
- 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:How many degrees of coke ignition temperature can ignite coke
- Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g
- 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?
- 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.
