1. Structure of Metallurgical Coke of Met coke of 30 to 90 mm 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.
Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.

5. FAQ
Do you have warehouse?
Yes,we have.
- Q: How to calculate the average particle size of coke
- Introduction of a commonly used, called "surface area volume average diameter", abbreviated D (3,2):D (3,2) = 1 / (fVI (/DI)).
- Q: The chemical composition of coke is m10.m25
- 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 is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.
- Q: Said the details can add points ah
- Visible: the two are called coke crushing strength index, has a certain correlation. Coking coking coal coke, the two general values are relatively large, and vice versa.The specific number of relations, to specific measurement of different manufacturers of coke M40 and M25 values, statistical regression, in order to determine.
- Q: Effect of coal fineness on coke
- The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
- Q: Coke boiler belongs to coal-fired boiler
- In addition, the utility model is characterized in that the utility model is used for heating and catering industry. Generally speaking, coke boiler belongs to coal fired boiler. Reason is that coke is a coal and fat coal for coke production.
- Q: What is the phosphorus content in coke
- After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)
- Q: What are the requirements for coke and other accounts?
- 4, I personally set the password and password.5, the customer I own the bank transfer agreement, my ID card, bank debit card to the corresponding bank outlets for bank transfer procedures.6, the day of the day to accept the phone call Futures Company visit, after the successful return of T+1 days of commodity futures trading.7, the customer into the gold (silver period transfer; non bank transfer).8, customer online transactions (start trading).
- Q: Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength 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%.
- Q: How long should it be to store coke in the open air
- And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.
- 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%
