Product Description:

1. Structure of CSR 64 Met  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.

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:The coke is divided into several separate uses
Gasification coke is used for the production of coke gas. The utility model is mainly used in a fixed bed coal gas producer with solid slag discharging, and is used as a gasification raw material to produce CO and H2 as combustible components. The main reaction of gasification process:C+O2 - CO2+408177KJ
Q:Relationship between coke M40 and M25
50 kilograms of size greater than 60 mm coke coke samples, in meters Qom in the drum at 50 rpm speed of 100 revolutions (4 minutes), with the aperture is 40 mm (25 mm) sieve screening, measuring more than 40 mm (25 mm) and the weight percentage of the coke, the total weight of the coke drum, denoted as M40 (or M25).
Q:What are the indicators of first grade coke and the two grade coke?
Two level 12.01-13.50 0.61-0.80 not less than 76 not greater than 9 not greater than 1.9Three level 13.51-15.00 0.81-1.00 not less than 72 not greater than 10 not greater than 1.9
Q:What is the amount of waste gas produced by a ton of coke burning
Process for producing coke, coke oven gas and coking chemical products by thermal decomposition and coking.
Q:What are the ingredients of coke
Two, coke distributionAccording to the distribution of coke production in China, the geographical distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china.Three, the use of cokeCoke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
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.
Q:What is the difference between coking coal and coke
Coking coal is an essential raw material for the production of coking coal, coking coal is one of the main uses of coke, coke is full of coking coal, coking coal is necessary for coke.
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:How much coke oven gas is produced?
From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
Q:The pulverized coal is separated from the air to enhance the heat, in addition to the main coke
The structure of benzene and toluene is similar, and the molecular composition is different from that of a CH2 atom cluster, which is called homologous;(5) the number of chloro compounds in the hydrogen molecule is equal to the number of hydrogen atoms in different environments, and toluene has four kinds of hydrogen atoms in different environments: methyl group on the top, the benzene ring on the top of the 3 species, and so on, there are 4 kinds of chlorine compounds in toluene,
