Product Description:

1. Structure of Met     Coke   of    CSR   62    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.

Coke production of coking coal (coking coal), also known as metallurgical coal, belongs to the bituminous coal or sub-bituminous coal. Or use the various ratio of coal blend coking. Coking coal in the coke oven is isolated from oxygen after 1000 ° C carbonization is volatile component has been removing, the rest of the solid matter or coke. With the need of ironmaking as little as possible of sulphur, phosphorus pests, so should choose low sulfur, low phosphorus of coking coal.

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

From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone. In China, the first kind of typical coal coking coal with hebei feng feng coal mine, shanxi gujiao cetrimonium, heilongjiang drops of jixi, anhui huaibei zhangzhuang and dabao top-coal panzhihua in sichuan province.The second category of typical coal coking coal have jilin tonghua iron works and the Inner Mongolia baotou beach ditch coal.Benxi, northeast China hebei tangshan, jingxing, shandong xinwen, etc., are all famous origin of coking coal.

Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:In the coke analysis index, M40% and M25% respectively mean what?
(1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
Q:Coke can be used to do what carbon black can be used to do?
2 carbon black is produced by compounds of carbon and carbon, the main hydrocarbon combustion, the combustion is not sufficient, can not be converted into carbon dioxide, is carbon monoxide, so as small particles of carbon particles, which is carbon black; carbon black can be used as filling agent of rubber mixture, preferably for tires.
Q:The chemical composition of coke m10.m25 refers to?
1, coal washing ((M25 drum index) metallurgical coke crushing strength is (M10 drum index) metallurgical coke wear strength is reflected
Q:The specifications for coke used in stainless steel smelting are as follows
Two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile < 1.9%; all 6% "0.7%" water; sulfur;
Q:Coking coal, coke, coal, steam coal what is the difference?
Coking coal is the raw material for coke
Q:What is the essential difference between coal and coke?
Coke]Coke is bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). 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.Coke 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:Coke coal charcoal are used for what
Manufacture of carburizing agentAll the requirements of the surface with high hardness and wear resistance, and the center has good toughness of all steel products to be carburizing. A carbonaceous mixture used for carburizing of steel products. Simple charcoal carburizing effect is poor. Therefore, commonly used charcoal as raw material, and then add a certain amount of contact agent, made of carburizing agent.
Q:Coke is how to produce, what is its purpose?
Natural coke. Coke can be obtained by high-temperature carbonization of coal:
Q:The difference between coke and coal
Coke is a product of wood processing, not the same
