1. Structure of Metallurgical Coke of COKE Breeze of 0 to 5mm 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 in the volatile: on the basis of judging the volatile content of coke coke maturity.Such as volatile matter is more than 1.5%, green said coke;Volatile is less than 0.5-0.7%, say, generally mature metallurgical coke volatilizes into 1%.
The moisture in coke: moisture fluctuations can make coke measurement, which cause the furnace condition fluctuation.In addition, coke moisture increase will make M40 on the high side, low M10, bring error to drum index.

5. FAQ
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.China's metallurgical coke quality standard (GB/T1996-94) is the quality standard of blast furnace.
- Q:What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?
- 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:What is the difference between coke and semi coke in ferrosilicon smelting process? In the process of energy statistics in the end should be 0.9714 of the conversion coefficient should be used with the conversion coefficient of 0.75 x 0.9714, please expert advice? emergencyUrgent!
- Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
- Q:8 points will be isolated from the air to enhance the heat of coal, in addition to the main coke, but also the material listed in the following table: No.
- Ethylene containing carbon carbon double bond can add poly to generate polyvinyl chloride, can be used for food packaging, reaction equation is: nCH2=CH2Initiator,The answer is: nCH2=CH2Initiator;
- 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:What is the density of coke?
- The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
- Q:What are the quality indicators of coke
- 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. Evaluation of the quality of coke, 1 of sulfur 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 phosphorus content in coke
- Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
- Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant
- Coking plant coal tower, primary cooling tower, cooling tower, etc.. The coal tower is used to store coal for coke oven. The cooling tower is used to cool the gas and cooling tower cooling water.
- 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
- As everyone knows, sulfur and phosphorus is harmful substances in the metal, because the sulfur is out in coke processing, so this index is not required, but the phosphorus in this process has not been effectively removed, so this is the requirement of foundry process or smelting plant. Phosphorus can reduce the strength of the metal, will lead to the metal "cold crisp", so to control the phosphorus content of coke, to prevent phosphorus into the metal.
- Q:In the coke analysis index, M40% and M25% respectively mean what?
- (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)
