Embodiment Construction

[0075] like figure 1 shown, figure 1 This is a schematic flow chart of an embodiment of the coal quality evaluation method of the present invention. In one embodiment, the coal quality evaluation method includes:

[0076] In step S10, the identification information of the coal type to be evaluated is obtained, and the identification information includes: the name of the coal type, the mining time, and the mining site;

[0077] Step S20, detecting whether there is target identity information consistent with the identity information in the database;

[0078] Step S30, if there is no target identification information consistent with the identification information, obtain industrial analysis index data of the coal type to be evaluated;

[0079] Step S40, inputting the industrial analysis index data into the evaluation formula corresponding to the name of the coal type to obtain an evaluation value;

[0080] Step S50, generating evaluation information of the coal type to be eva...

Abstract

The invention discloses a coal quality evaluation method and device. The method includes: obtaining the identity information of the coal type to be evaluated, and the identity information includes: the name of the coal type, the mining time, and the mining point; The target identity information consistent with the identity information; if there is no target identity information consistent with the identity information, then obtain the industrial analysis index data of the coal type to be evaluated; the industrial analysis index data Inputting an evaluation formula corresponding to the name of the coal type to obtain an evaluation value; generating evaluation information of the coal type to be evaluated according to the evaluation value. Through the present invention, according to the name of the coal type, the evaluation formula corresponding to the name of the coal type is used to evaluate the coal type, thereby realizing the accurate evaluation of the coal type.

Description

technical field [0001] The invention relates to the technical field of coal, in particular to a method and device for evaluating coal quality. Background technique [0002] The status of coke as a heating agent, reducing agent and carburizing agent for blast furnace ironmaking is irreplaceable, and the important role of skeleton is more prominent. The quality of coke is directly related to blast furnace production. In other words, the quality of coke determines the quality of Its ability to play a role in the skeleton of the blast furnace and seriously affect the operation, continuation and efficiency of the blast furnace, so major steel mills are working hard to improve and improve the quality of coke. [0003] The coke is obtained by dry distillation of coal at a high temperature of about 1000 ° C. Therefore, in order to ensure the quality of the coke, it is first necessary to ensure the quality of the coal used for coking. However, a complete coal quality evaluation syst...
