Product Description:

1. Structure of CRI  30%   Metallurgical  Coke  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. Separate focal piece of micro cracks along, namely coke porous body, also known as coke. Focal body consists of porosity and the pore wall, hole wall is also called the coke quality, its main component is carbon and minerals. How much coke crack directly affect the size and crushing strength of coke. Focal piece of micro cracks and holes spore structure of coke and abrasive resistance and high temperature reaction performance of coke has a close relationship. Spore structure usually use stomata average pore size and pore size distribution, specific surface area and pore wall thickness parameter.

5. FAQ

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

1) How about your company

Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.

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:Mechanism of carbon and coke is not the same as the price which high?
Stick out almost all with crack. And they say the yield of 180 kg / hour also is very different, not only the normal production hours when the output of 100 kilograms. I had also directed his blog to the thought, the personality is good. It seems that I really fooled. Later on the Internet listen to friends that they and Beijing Shouke, and sell equipment are a group of Shouke and powerful equipment are factory Hebei Ba Chau do, the technician will not help garbage shit escape love who are also the factory to help Hebei Ba Chau cultivated. It is the general black crow. The wolf escaped, and ventured into the mouth. I put my story and I just hope I don't have the same people cheated, Juyuan suzerain is the biggest liar. Equipment market is too dirty, the bone charcoal mechanism shall not ah!
Q:What is the amount of waste gas produced by a ton of coke burning
Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent
Q:How much coke can a ton of coal
The ratio is about 1 to 0.7, that is to say, 1 kilograms of about 0.7 kg coke coking coal coke, coke did not reach 0.75 kg, 0.71.Don't listen to them char 1.4:1, personal feeling.
Q:What are the requirements for the quality of coke in blast furnace smelting
Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%.Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. 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:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
Q:How to distinguish the level of coke. What is metallurgical coke
The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke "
Q:What are the main uses of coke
The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
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 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:Purpose of using coke in iron making raw materials
The coke can provide the heat required for the reaction and has the reducibility
