Q:I now do a good job in the coke network editor, I would like to know more about coke

Direct reduction in the blast furnace in the area above 850 degrees celsius. Because the CO2 generated at high temperature immediately reacts with the carbon in coke to form CO, it can be considered that the carbon in coke is directly involved in the reduction process:CO is used as reducing agent, either indirect or direct reduction. In order to continue to add CO, requires a certain degree of reactivity of coke.

Q:What is the effect of coke moisture on the blast furnace?

1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.

Q:Natural gas can replace coke smelting pig iron

No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2

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:How to determine the maturity of coke or not?

Ash in coke: the percentage of ash contained in metallurgical coke. The influence of coke ash on blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%. Therefore, it is necessary to reduce the ash content of coke.The volatile content in coke: refers to the percentage of the total amount of volatiles in metallurgical coke. Coke maturity can be judged according to the volatile content of coke. If the volatile content is greater than 1.5%, it is said that coke; volatile less than 0.5 - 0.7%, it is said to burn; generally mature metallurgical coke volatile is divided into about 1%.

Q:Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers

To be exact, you don't need coke for steelmaking, you say that it's iron making

Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between

3, calcium carbide coke is conductive body and a heating body for electric arc furnace of coke in the production of calcium carbide. Calcium carbide with coke into the electric arc furnace, arc heat and heat resistance at high temperature (1800-2200 degrees Celsius) under the action of complex reaction and lime, calcium carbide formation in the molten state (carbide). The generation process of the following reaction type available:CaO+3C - CaC2+CO-46.52KLCalcium carbide with coke should have low ash, high reactivity and high resistivity and grain size. The secondary characteristics, but also try to remove the powder and reduce moisture. Its chemical composition and particle size should meet the following requirement: >84% <14% fixed carbon, ash, volatile <2.0%, sulfur

Q:Standard grade two grade coke standard

Evaluation of coke quality1, 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%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.

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 are the main uses of coke

Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
