1. Structure of NUT Coke  of  Size is  5 ---  15  mm 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.

To ensure the quality of coke, the choice is the most basic requirements of coking coal volatile matter, caking and coking properties; the vast majority of coking coal must go through washing, as much as possible to ensure low ash content, sulfur content and phosphorus content. When choosing a coking coal, but also must pay attention to the inflation pressure in the process of coal in coking. With low volatile coal coking, due to its colloid viscosity big, prone to high inflation pressure, harms the coke oven masonry, needs to be addressed by coal blending coking.

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

Our country's metallurgical industry has a long history, is the original fuel charcoal smelting industry, due to the charcoal burning temperature is lower, and short duration of fire and not easy to master hour, therefore, directly affect the level of smelting, to make the steel quality is not guaranteed. Later, people use coal as smelting, coal combustion temperature is higher, and the combustion duration is longer than charcoal, but easily broken after coal is heated in the oven, affect the burden of permeability, and high content of sulfur in coal, directly affect the quality of the cast iron. After a period of practice, it has been found that the coal after dry distillation (i.e., separated flame heating), volatile components may be removed, and the porosity increased, resembling charcoal, fire is better than that of coal, but also can avoid charcoal and coal. This after carbonization of coal is 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: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:How to calculate the average particle size of coke
Introduction of a commonly used, called "surface area volume average diameter", abbreviated D (3,2):D (3,2) = 1 / (fVI (/DI)).
Q:How much coke can a ton of coal
But before the words to use 1.5 tons of coking coal to produce a total of 1 tons of coke
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 are the companies that produce coke
Know where you are, there is a good Wuxi, if necessary, can be introduced to you
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:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
If the paste pot may wish to try the following several waysBrush pot1, with hot water can be, it is easy to wash, do not use wire brush the ball, put the pot brush bad, if it is aluminum brush used for cooking after eating on the body is very good. (if you must brush it, you can use the cloth to replace the steel ball)
Q:The difference between semi coke and coke
Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
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:Purpose of using coke in iron making raw materials
The coke can provide the heat required for the reaction and has the reducibility
