1. Structure of Metallurgical Coke of Coke Strength after Reactivity 60 Description：
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
Coke reactivity and carbon dioxide, oxygen and water vapor on the ability of chemical reaction, CRI = (G0, G1 / G0 x 100% (note: coke G0 - test sample weight, g, G1 - coke after reaction sample weight, g).Coke after coke strength after reaction is refers to the response under the action of thermal stress and mechanical force and resistance to fracture and wear ability.Coke in the blast furnace ironmaking, casting iron and fixed bed gasification process, will react with carbon dioxide, oxygen and water vapor.Due to the reaction of coke with oxygen and water vapor and carbon dioxide reaction similar laws, so most countries use coke reaction with carbon dioxide features assess coke reactivity.
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
The physical properties of the coke with room temperature mechanical properties and thermal strength and chemical properties are closely related
- Q: What are the companies that produce coke
- Know where you are, there is a good Wuxi, if necessary, can be introduced to you
- Q: Standard grade two grade coke standard
- 5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
- 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: What are the indicators of first grade coke and the two grade coke?
- The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)
- Q: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
- Q: How to remove the bottom of coke steel
- Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.
- 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: Natural gas can replace coke smelting pig iron
- Coke at high temperature (also some blast furnace pulverized coal, heavy oil, natural gas and other auxiliary fuel) in carbon with bubbling air oxygen in the combustion of carbon monoxide and hydrogen generated in the furnace, removing the rise in iron ore in the process of oxygen, thereby reducing iron. The molten iron is released from the taphole. An iron ore, which is a mixture of non - reducing impurities, such as limestone, to form a slag from the slag. The produced gas is discharged from the top of the furnace, and is used as a fuel for a hot blast stove, a heating furnace, a coke oven, a boiler, etc.. Blast furnace smelting is the main product of pig iron, as well as by-products of blast furnace slag and blast furnace gas.
- Q: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- The concept of coke: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 of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should be Preparation of large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- 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
