Sudden drop in coke reactivity?
Thread Content
Recently, after changing the coal blending ratio, the reactivity of coke has decreased. Is it related to the lean nature of the blending coal? Please help analyze the reasons! Process: Tamping.
:lol :lol Both being underweight and compaction affect the reactivity of coke:handshake :handshake
If the client wants to ask this question, it’s best to provide the coal blending ratio as well as the quality parameters of the blended coal; this way, everyone can make a quantitative comparison to determine whether the issue lies with the coal or with the heating parameters
Coke reactivity is mainly determined by the quality of the coal blend; a leaner blend may have an impact, and it’s possible this also affects your M10 value
Coke reactivity is primarily determined by the quality of the coal blend; check whether there are any issues with the coal blend and whether it has been mixed evenly
The decrease in reactivity may be due to the excessive inclusion of your low-cohesion coal, and M10 also has a certain impact!
The coal blend has low volatility, insufficient porosity in the coke, and an excessive amount of thinning agents.:lol :handshake
A decrease in reactivity may be due to an excessive amount of weakly caking coal being included. However, for ramming coking, an excessive amount of highly cohesive coal can also lead to a decrease in reactivity. In summary, coke reactivity is primarily determined by the quality of the coal blend. It is best to conduct small coke oven tests before changing the coal blending ratio.
It is mainly due to coal blending; nowadays, coal suppliers already blend the coal before it leaves the factory. This situation occurs in about 1/3 of the primary coking coals: Q
Today’s coal owners already have it prepared at the time of production; this is the case for 1/3 of the primary coking coal. To ensure stable and reliable coal blending, it is important to monitor the stability of the incoming coal.
The process remains unchanged; the main reason is the coal blending issue.
