Q: The difference between coal and coke: The semi coke production tend to low temperature carbonization, distillation temperature at 600 degrees Celsius, due to a late start, at present the low temperature carbonization furnace single furnace annual output of 30 thousand tons / year in most equipment under low temperature carbonization furnace forum of more than 50 thousand tons / year scale is still at the exploratory and experimental stage, technology of the large-scale equipment is still not mature, can only achieve centralized mass production using a combination of multi furnace technology. The use of coal field is quite widespread, especially in the carbonaceous reducing agent has unique properties, economic advantages are very obvious.

Q: The chemical composition of coke is m10.m25: Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength

Q: Coking coal, coke, coal, steam coal what is the difference?: Coking coal is the raw material for coke

Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?: Yes；To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;

Q: Why is coke used in blast furnace steelmaking?Why not use coal?: The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.

Q: What's the connection between coking coal and coke: Coking coal is divided into two categories, the first category of coking coal dry ash free volatile Vdaf>10% ~ 28%, G>65 bond index, thickness, y = 25mm. This part of the coking coal is particularly good, can separate the qualified blast furnace coke. Another kind of coking coal dry ash based volatile Vdaf>20% ~ 28%, caking index G>50 ~ 65, coking than the former difference. Coking coal is a kind of typical coking coal, which has a good thermal stability

Q: What is the difference between the industrial analysis of coke and the industrial analysis of coal samples: Coke GB/T 1996-2003, volatile coke is the most difficult to do

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: Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you: Phosphorus is a kind of harmful element in metal, which reduces the mechanical properties of castings. Under normal circumstances, GB castings of phosphorus content requirements of less than 0.06%, the lower the special requirements

Q: Mechanism of carbon and coke is not the same as the price which high?: Now, carbon factory has been discontinued, I start the original work - cable maintenance. The first floor of the post is my hair, said all no empty words. A combination of equipment quality is too bad, and Beijing Shougang, cleaning the equipment of large and the fact they are and exactly the same. Beijing is a liar equipment. Zhang Lian do is a donkey trading, factory equipment do Ba Chau are defective, they sold to Beijing fake technology company. I was at his factory inspection equipment of Shougang crooks in the factory. They stay trapped the loss of numerous investors. I now have been unable to recover
