[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0040] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0041] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0042] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] Figure 1 A flow chart showing a method for determining the strength of coke after reaction in an embodiment of the present application is shown, see Figure 1 , provides a method for determining the strength of coke after reaction, including at least S1 to S2, which are described in detail as follows:

[0044] In step S1, the volatile matter, caking index and coarse-grained mosaic structure content of the target coal sample are measured.

[0045] In step S2, the post-coke reaction strength of the target coal sample is determined according to the volatile matter of the target coal sample, the caking index of the target coal sample and the coarse-grained mosaic structure content of the target coal sample. On the one hand, the coarse-grained mosaic structure has a low reactivity with carbon dioxide (CO2). The coal sample with a higher content of coarse-grained mosaic structure has a lower reactivity (CRI) and a higher coke strength after reaction (CSR). Therefore, the coke strength after reaction is related to the content of coarse-grained mosaic structure, and the content of coarse-grained mosaic structure is used as a parameter to determine the coke strength after reaction; on the other hand, the coke strength after reaction is related to the porosity and pore wall thickness of the coke. The smaller the porosity and the thicker the pore wall, the higher the coke density and the coke strength after reaction. The value of volatile matter can characterize the pore structure of the coke. The higher the volatile matter, the greater the porosity and the smaller the pore wall thickness. Therefore, the volatile matter is used as a parameter to determine the coke strength after reaction; on the other hand, some lean coking coals with a high degree of metamorphism have a lower volatile matter and a higher coke density, but if the cohesiveness is poor, the coke strength after reaction will decrease. Therefore, the cohesiveness index (G value) that can characterize the cohesiveness is used as a parameter to determine the coke strength after reaction.

[0046] In some embodiments, the determination of the coke reaction strength of the target coal sample according to the volatile matter of the target coal sample, the caking index of the target coal sample and the coarse-grained mosaic structure content of the target coal sample includes: determining the target relationship of volatile matter, caking index, coarse-grained mosaic structure content and coke reaction strength according to the measured values ​​of the volatile matter, caking index, coarse-grained mosaic structure content and coke reaction strength of the measured coal sample; based on the target relationship, determining the coke reaction strength of the target coal sample according to the volatile matter of the target coal sample, the caking index of the target coal sample and the coarse-grained mosaic structure content of the target coal sample. The target relationship can be a formula, i.e., a formula with volatile matter, caking index and coarse-grained mosaic structure content as independent variables and coke reaction strength as dependent variable, or it can be in a table form, i.e., a table in which a set of volatile matter, caking index and coarse-grained mosaic structure corresponds to one coke reaction strength.

[0047] In some embodiments, the target relationship is a determination formula, and the target relationship among volatile matter, caking index, coarse-grained mosaic structure content and coke strength after reaction is determined according to the measured values ​​of volatile matter, caking index, coarse-grained mosaic structure content and coke strength after reaction of the actually measured coal sample, including: establishing a linear model with volatile matter, caking index and coarse-grained mosaic structure content as input parameters and coke strength after reaction as output parameter; based on the linear model, using the least squares method to fit the model according to the measured values ​​of volatile matter, caking index, coarse-grained mosaic structure content and coke strength after reaction of the actually measured coal sample, to obtain the determination formula.

[0053] In some embodiments, determining the interaction term between volatile matter and bonding index, the interaction term between bonding index and coarse-grained mosaic structure content, and the interaction term between coarse-grained mosaic structure content and volatile matter includes: determining a first difference between volatile matter and a first value, a second difference between bonding index and a second value, and a third difference between coarse-grained mosaic structure content and a third value; multiplying the first difference by the second difference to obtain the interaction term between volatile matter and bonding index; multiplying the second difference by the third difference to obtain the interaction term between bonding index and coarse-grained mosaic structure content; multiplying the third difference by the first difference to obtain the interaction term between coarse-grained mosaic structure content and volatile matter.

[0054] In some embodiments, the second linear model is: CSR = β0 + β1 * V daf +β2*G+β3*P+β4*V daf *G+β5*G*P+β5*P*V daf +∈, where β0 is the intercept, β1 is the first coefficient, Vdaf is the volatile matter, β2 is the second coefficient, G is the bonding index, β3 is the third coefficient, P is the coarse-grained mosaic structure content, β4 is the fourth coefficient, β5 is the fifth coefficient, β6 is the sixth coefficient, and ∈ is the error term.
