1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 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.

Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1)Main type

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.

2) Application of coke

     Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury

     Other non-ferrous metal smelting of blast furnace,

     Reducing agent, compound

     The function of stock column frame.

3) The history of coke

Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.

Although the use of coke earliest in our country, but has not seen through the records. Coking and the earliest recorded with coke can be found in the late Ming dynasty in China side to write the physical knowledge, he pointed out that coal everywhere all have, "smelly burning-out and closed into stone, chisel and charging again yue reef (coke), May 5, fire, cook Fried mine stone, will save Labour". This smelly coal, it is to point to contain volatiles more coking coal, the coal sealed burning-out, becomes hard coke, used for smelting, the effect is very good.

Q:How many degrees of coke ignition temperature can ignite coke
The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;
Q:What is the reasonable ratio of coal to coke
Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material
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 is the difference between coke and coking coal
Coke: a solid fuel, hard, porous, high calorific value coal. High temperature carbonization made for ironmakingTypes of coke:Coke 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:Coke is how to produce, what is its purpose?
Natural coke. Coke can be obtained by high-temperature carbonization of coal:
Q:How coke is involved in steelmaking,
Molten iron is produced in a reducing atmosphere of the blast furnace, which is then supplied to the steelmaking plant for steelmaking.
Q:Sulphur content of coal and coke,
The sulfur content of coking coal basically all into the coke, only a small number into the gas but the number is very limited. How much coal is the amount of sulfur in the general coal is the sulfur. It should be said that coke is basically a little lower and a little bit limited.In the process of coking volatile will be a lot of consumption, ash will increase 2-3%.
Q:How much coal can a kilogram of coal weigh?
The ratio is about 1 to about 0.7, that is, about 1 kilograms of coking coal can produce a total of about 0.7 kg of coke
Q:What is the density of coke?
There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
Q:What does the M40% and M25% mean in the analysis of coke?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
