1. Structure of Metallurgical Coke of The met coke of 40-100mm Description：
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
In order to ensure the coking coal resources of domestic demand, to carry out the national energy conservation and emissions reduction program, China has many policies to control of coke export, export enterprises enthusiasm obviously inadequate.2009 countries in two batch issued 11.91 million tons of coke quota, and 12.01 million tons of export quotas flat in 2008.In the current import under the condition of weak demand, coke quota is too enough.

Brazil, India and other countries with the improving gradually form a complete set of coke production capacity, the more inclined to imports of coking coal from coking, dependency of China's coke has a tendency to gradually reduce.
- Q: What is the difference between metallurgical coke and chemical coke
- Quality index of cokeCoke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). 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). 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. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
- Q: How to calculate the average particle size of coke
- Broken before and after the comparison of granularity, see D50 on the line. There are many kinds of average grain size, and the calculation steps are more complicated.
- Q: Types of coke and use of coke
- Generally speaking, the use of coke in the following industries: blast furnace ironmaking, mechanical casting, calcium carbide production, processing Ferroalloy, chemical fertilizer, gas and high-tech high value-added industries
- Q: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
- From the heat, the quality of coke is generally greater than the quality of coal, such as coal, coal and the use of this kind of coal coke, coke prices higher.
- Q: What kind of coke is needed for smelting special steel
- 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: Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?
- If the control is not good, the manganese content in the molten iron can be increased by increasing the reagent
- 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 bonds can react with bromine and bromine, and reaction of bleaching, b.:
- Q: The cost of iron ore and coke
- At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
- Q: How many degrees of coke ignition temperature can ignite coke
- Ignition temperature (450-650) in air;The main physical properties of coke are as follows:True density is 1.8-1.95g/cm3;Apparent density of 0.88-1.08g/ cm3;
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- Quality index of cokeCoke is the solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index generally refers to the unit volume of the crack (crack number within the coke grain length). To measure the pore structure of the main indicators to measure with porosity (only coke pore volume accounted for percentage of the total volume) that it affects the coke reactivity and strength. The different uses of the coke porosity index for different requirements, the general metallurgical coke gas hole rate in 40 ~ 45%, foundry requirements in 35 ~ 40%, coke export requirements in 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 and coking coal as a base; Coke coal refining. Crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of two indicators. The coke crushing strength is that coke can resist foreign impact force without ability along cracks or defects at the broken table, shown by M40 wear; strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, M10 value and abrasion strength influence of coke pore structure. M40 and M10 were determined by lot. In China the migon drum test in Germany.
