Product Description:

1. Structure of Metallurgical Coke of NUT COKE of 20 - 40mm Description:

The physical properties of the coke with room temperature mechanical properties and thermal strength and chemical properties are closely related.Coke's main physical properties are as follows:
The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)
Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);
Ignition temperature (air) is 450-650 ℃;
Low calorific value of dry ash-free basis for 30-32 kj/g;

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

5. FAQ

In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.

Q:Purpose of using coke in iron making raw materials
Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron
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 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:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Shanlihong to paste potIf the bottom of the pot cooking, cooking paste, can put a few shanlihong put the pot, add a little cold water boil (not dry), paste pot bottom will soon get rid of.
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
Coal is the raw material that has not been treated by coking. Not every kind of coal for coke, according to the different requirements of the different kinds of coal
Q:What is the difference between coking coal and coke
Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
Q:What is cokeWhat applications are, what is the fire of Malachite copper
Malachite is a kind of copper, copper smelting with coke burning malachite is under high temperature.
Q:Dry or dry carbon carbon, coke or coke, and I do not know which word of
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:What is the reasonable standard of volatile content of coke
The sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%.
