Product Description:


1. Structure of Metallurgical Coke of Nut Coke of 20-50mm Description:

Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.

5. FAQ

Analysis of coking coal supply and demand, to pay attention to the coke import and export situation in China.Due to the coke export prices and domestic price linkage, basically at the same time the quota also play a key role.

Q:How to determine the maturity of coke or not?
Ash in coke: the percentage of ash contained in metallurgical coke. The influence of coke ash on blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%. Therefore, it is necessary to reduce the ash content of coke.The volatile content in coke: refers to the percentage of the total amount of volatiles in metallurgical coke. Coke maturity can be judged according to the volatile content of coke. If the volatile content is greater than 1.5%, it is said that coke; volatile less than 0.5 - 0.7%, it is said to burn; generally mature metallurgical coke volatile is divided into about 1%.
Q:What is the difference between metallurgical coke and chemical coke
The chemical composition of coke including fixed carbon, ash, sulfur, volatile matter and moisture. Except moisture, other ingredients in dry coke, is an important raw material of cupola smelting, casting of the components of specific inspection requirements.
Q:Coking tower and coke tower is what relationship?
Coking plant production capacity on the exclusion of the tower is also on the two: first, the coal tower; the two is coke bin;
Q:Effect of coke powder ratio on the index
2, the phosphorus content of coke: iron metallurgical coke content should be 0.02 - 0.03%.3, coke ash: blast furnace coke ash effect is very significant. The amount of coke ash in coke increased by 1%, an increase of 2 - 2.5%., therefore, a decrease in coke ash is necessary4, coke volatile: according to the coke can be judged by the volatile content of volatile volatile is greater than 1.5%, then the coke; volatile less than 0.5 - 0.7%, which means that too much, generally mature volatile metallurgical coke to about 1%.5, coke moisture: moisture fluctuations should not be measured in coke, causing fluctuations in the furnace conditions. In addition, increased M04 coke moisture content high, low M10, the drum index error
Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
There are also ISO and ASTM, I do not know what you want the standard?
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
Q:What does Coke test index M25 mean?
Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. 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)
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:What is the phosphorus content in 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.
Q:Various types of coal coke are the main test items
If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
