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 ingredients of coke

Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.

Q:Coke is how to produce, what is its purpose?

Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.

Q:In the coke analysis index, M40% and M25% respectively mean what?

(1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.

Q:Various types of coal coke are the main test items

If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.

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

Two, the type of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace

Q:Coke boiler belongs to coal-fired boiler

Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.

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:Coke and coal is one thing

Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
