Description

Technical Field

[0001] The present invention relates to the field of metallurgical technology, and in particular to a method for establishing metallurgical specifications in an ERP system. Background Art

[0002] In the modern metallurgical industry, enterprises are faced with increasingly complex production and management needs. Traditional management methods often rely on manual processing and local systems, resulting in information islands, inconsistent data, long response times, and inefficient use of resources. This situation not only restricts the agility and competitiveness of enterprises, but also affects the stability of product quality and the improvement of production efficiency. Therefore, it is becoming increasingly important to carry out an effective metallurgical specification construction, especially the integration in the enterprise resource planning (ERP) system.

[0003] At present, the metallurgical specification maintenance mode of steel enterprises is to independently establish a metallurgical specification code for each steel project. In the ERP system, the metallurgical specification code cannot be used to distinguish product information, resulting in the inability of production planners to perform unified one-time production scheduling for multiple steel grades, causing an increase in surplus billets and mixed billets, thereby increasing steel production costs. Summary of the invention

[0004] To solve the above problems, an embodiment of the present invention aims to provide a method for establishing metallurgical specifications in an ERP system.

[0005] A method for establishing metallurgical specifications in an ERP system, comprising:

[0006] Step 1: Collect process control parameters of different steel grades in each process;

[0007] Step 2: Inspect the process control parameters of each process to form the inspected process control parameters;

[0008] Step 3: Set a unique metallurgical specification code for the steel type corresponding to the inspected process control parameters;

[0009] Step 4: Store the metallurgical specification codes in the ERP system to guide the batch production of different steel grades.

[0010] Preferably, step 2: inspecting the process control parameters of each process step to form inspected process control parameters, including:

[0011] Arrange the process control parameters of each process in ascending order according to the output of each steel grade to obtain a control parameter sequence;

[0012] Calculate the test coefficients of the control parameter sequences of adjacent groups;

[0013] When the value of the test coefficient is not within the preset range, the corresponding control parameter sequence is deleted.

[0014] Preferably, the test coefficient calculation formula is:

[0015]

[0016] Among them, p X,Y is the test coefficient, cov(X,Y) represents the covariance between the current control parameter sequence X and the previous set of control parameter sequence Y, σ X represents the variance of the current control parameter sequence X, σ Y Represents the variance of the previous set of control parameter sequence Y.
