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

However, it will be appreciated by those skilled in the art 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, implementations 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 separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[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 to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. 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. Figure 1 , provides a method for determining the strength of coke after reaction, including at least S1 to S2, which are detailed 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 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). Coal samples with a higher content of coarse-grained mosaic structure have a lower reactivity index (CRI) and a higher coke strength after reaction (CSR). Therefore, the coke strength after reaction is related to the coarse-grained mosaic structure content, and the coarse-grained mosaic structure content 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 volatile matter value 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 higher degree of metamorphism have a lower volatile matter and a higher coke density. However, if the cohesiveness is poor, the coke strength after reaction will decrease. Therefore, the cohesiveness index (G value), which can characterize the cohesiveness, is used as a parameter to determine the coke strength after reaction.

[0046] In some embodiments, determining the coke-reaction strength of the target coal sample based on the volatile matter, the caking index, and the coarse-grained mosaic structure content of the target coal sample comprises: determining a target relationship among volatile matter, caking index, coarse-grained mosaic structure content, and coke-reaction strength based on the measured values ​​of the volatile matter, caking index, coarse-grained mosaic structure content, and coke-reaction strength of the actually measured coal sample; and determining the coke-reaction strength of the target coal sample based on the volatile matter, caking index, and coarse-grained mosaic structure content of the target coal sample based on the target relationship. The target relationship may 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 may be in a table, 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 of volatile matter, caking index, coarse-grained mosaic structure content and coke reaction strength is determined based on the measured values ​​of volatile matter, caking index, coarse-grained mosaic structure content and coke reaction strength of the measured coal sample, including: establishing a linear model with volatile matter, caking index and coarse-grained mosaic structure content as input parameters and coke reaction strength 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 reaction strength of the measured coal sample to obtain the determination formula.

[0048] In some embodiments, the linear model is established with volatile matter, caking index, and coarse-grained mosaic structure content as input parameters and the coke reaction strength as output parameter, including: establishing a first linear model based on volatile matter, caking index, coarse-grained mosaic structure content, a first coefficient, a second coefficient, and a third coefficient, wherein the first coefficient is the coefficient of volatile matter, the second coefficient is the coefficient of caking index, and the third coefficient is the coefficient of coarse-grained mosaic structure content.

[0051] In some embodiments, before establishing the second linear model based on the volatile matter, bonding index, coarse-grained mosaic structure content, the first coefficient, the second coefficient, the third coefficient, the fourth coefficient, the fifth coefficient and the sixth coefficient, it also includes: determining the interaction term between the volatile matter and the bonding index, the interaction term between the bonding index and the coarse-grained mosaic structure content, and the interaction term between the coarse-grained mosaic structure content and the volatile matter.

[0052] 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: multiplying the volatile matter and the bonding index to obtain the interaction term between the volatile matter and the bonding index; multiplying the interaction term between the bonding index and the coarse-grained mosaic structure content to obtain the interaction term between the bonding index and the coarse-grained mosaic structure content; and multiplying the coarse-grained mosaic structure content and the volatile matter to obtain the interaction term between the coarse-grained mosaic structure content and the volatile matter.

[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; and 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+ε, where β0 is the intercept, β1 is the first coefficient, V daf 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 ε is the error term.

[0055] In some embodiments, the second linear model is: CSR=β0+β1*V daf +β2*G+β3*P+β4*(V daf -a1)*(G-a2)+β5* (G-a2) *(P -a3)+β5*(P -a3)* (V daf -a1) + ε, where β0 is the intercept, β1 is the first coefficient, V daf 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, a1 is the first value, a2 is the second value, β5 is the fifth coefficient, a3 is the third value, β6 is the sixth coefficient, and ε is the error term.

[0057] For example, according to the above determination formula, the strength of the coke after reaction is obtained as shown in Table 1.

[0058] Table 1

[0059]

[0060] Table 2 shows a comparison table of the coke reaction strength obtained according to the determination method and the measured value of the coke reaction strength. Referring to Table 2, the error rate between the two is between 0.04 and 8.47%, the overall error is small, and the determination accuracy is high.

[0061] Table 2

[0062]

[0063] In some embodiments, the quality of coking coal is graded according to the CSR. Coking coal with a CSR ≥ 65% can be classified as Class 1, coking coal with a CSR between 55 and 65% can be classified as Class 2, and coking coal with a CSR below 55% can be classified as Class 3.

[0064] In some embodiments, the measuring of the volatile matter, caking index and coarse-grained mosaic structure content of the target coal sample includes: heating the target coal sample to a preset temperature under air-tight conditions, and measuring the mass reduction of the target coal sample during the heating process to determine the volatile matter; mixing the target coal sample with standard anthracite, and heating under preset conditions to form a coke block, and determining the caking index by measuring the strength or compressive resistance of the coke block; observing the surface and fracture surface of the target coal sample with a microscope, or analyzing the pore structure of the target coal sample with CT technology to determine the coarse-grained mosaic structure content.
