Further Discussion on Coal Blending Optimization
Thread Content
Currently, the coal types used in coal washing plants are of varying quality. To meet the requirements for coal used in coking, any type of coal is willing to be mixed in, as long as its parameters meet the standards; yet the quality of the coal is getting worse and worse. Traditional approaches to coal blending seem inadequate to handle this situation, so it’s necessary for everyone to discuss this issue
At this point, strict control is necessary over the coal source; if the supply of coal is well controlled, the composition of the coal mixture will remain relatively stable
The coal blending quality in coal washing plants is also getting better and better these days. At first, the standards are acceptable, but after some time there are definitely fluctuations; if you manage to control them, they can adjust the standards right away, which makes it quite flexible! Sometimes, sampling before weighing is also used for control!
To maintain stable coke quality, it is necessary to control the coal source and fix the mining locations; reliance must be placed on coal supplied by coal washing plants. Traditional coal blending criteria are difficult to control, and in order to maximize profits, coal washing companies mix different types of coal, which makes it hard for coking companies to maintain control.
The evaluation criteria for coal input need to be innovated; traditional criteria have significant flaws. The coal used for coking these days is actually synthetically produced coal, and even if the criteria are appropriate, the coke produced as a result is not of good quality. :funk: :funk: :funk: :L
If we have suitable raw coal, we wash it ourselves.
For independent coking, it is best to have one's own coal mine.
I agree with the original poster’s view; SM and 1/3 JM can be mixed to form JM by adjusting the proportions, and the JM that our factory purchases is of this type. If everyone has the opportunity to study coal petrology, they can avoid being deceived; currently, the Coking and Refractories Research Institute is able to conduct such tests. Can the test results be used to sue the coal supplier? Coking time has generally increased, and coking coal suppliers should consider reducing prices as well as improving coal quality.
It is possible to use coal rock theory, but after all it is not a conventional method for on-site testing, which poses testing challenges for coking enterprises: L :L :L :funk:
Several companies (that are located nearby) can combine their efforts to purchase coal and rock testing equipment for such tests. The contract specifies strict penalties for mixing different types of coal, which can effectively solve the problem; no matter what type of coal it is, there will be no random mixing. Domestic ones are relatively cheap, and coking enterprises can afford them. It’s just skipping a few meals, right?
