CNBM MET COKE of 20 -80mm

1.We export many kinds of coke, such as metallurgical coke (met coke) of 20-80 mm, theNUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on. The main source isShanxi coking plant.

Magnetite iron ore is also used to make synthetic ammonia catalysts (pure), natural mineral pigments (specularite, limonite, hematite), feed additives, magnetite, hematite and limonite) and rare healing stone (magnet) and so on, but few dosage.Iron and steel products are widely used in departments of national economy and people's all aspects of life, is the social production and public life the necessary basic materials.

2.Our CNBM MET COKE of 40 -100mm are ideal for:

• Quality assurance

• Mutual benefit

• Preferential price

• Various choice

4.FAQ

What are coke's main physical properties?

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.

The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)

Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);

Ignition temperature (air) is 450-650 ℃.

Q: Coke is how to make it? What is the use?: Coke production has prepared the material into the coal charging car from coal tower, were sent to the furnace chamber. The gas produced by the dry distillation is sent to the chemical product recovery workshop for processing. After a coking period (from charging to pushing the required time is generally 14 to 18 hours, depending on the carbonization chamber and the width), a pusher will mature by refining coke coke machine into the coke car; coke quenching, coke is discharged into the cold coke; then screening and storage (Figure 4).The coking plant is generally composed of two coke ovens. The two coke ovens are arranged on the same central line, and a coal tower is arranged in the middle. A furnace with coke oven machinery -- corresponding charging car and coke machine, machine coke, coke quenching car and motor vehicle; also equipped with a set of facilities including coke quenching, coke quenching tower, coke quenching pump, coke powder and coke powder sedimentation tank grab, arranged in the end furnace group. The center of the coke quenching tower is not less than 40 meters from the center of the carbonization chamber. If dry coke quenching, coke oven station. The coking plant is also equipped with the necessary piping and reversing system.

Q: What chemical plant used to coke: . 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

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: Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?: The level of spheroidization is not enough. The final sulfur content of molten iron before the spheroidizing treatment is best at 0.03%

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 does the M40% and M25% mean in the analysis of coke?: (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)

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: What is the effect of coke moisture on the blast furnace?: 1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.

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: How to determine the maturity of coke or not?: The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
