Product Description:

CNBM MET COKE of 30  -90mm

1.We export many kinds of coke, such as metallurgical coke (met coke) of 30-90 mm, theNUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on. The main source isShanxi coking plant. 

       Is usually divided into pig iron for steel making according to the use of cast iron, cast iron, alloy cast iron.Steel according to different elements are divided into carbon steel, alloy steel.Alloy steel is on the basis of carbon steel, to improve the performance or get some intending to join the right amount of one or more elements of the steel, add a lot of more phyletic, the elements of steel mainly include chromium, manganese, vanadium, titanium, nickel, molybdenum, silicon.

Q:Coke indicators are divided into grades
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: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:Coke and coal is one thing
Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
Q:What is coke and how is coke classified?
Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.
Q:Sulphur content of coal and coke,
80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.
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:Why does casting coke require phosphorus?
Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
Q:What is the reasonable standard of volatile content of coke
Generally speaking, the volatile content of coke is about 1.5 or so, but not more than 2
Q:What are the ingredients of coke
The chemical composition of coke including fixed carbon, ash, sulfur, volatile matter and moisture. Except moisture, other ingredients in dry coke as basis.
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.
