Abstract

The invention provides a method for carrying out virtual steel rolling by using historical data. The method of the invention comprises the following steps of: (1) designing an interface: dividing theinterface into a new plan preparation screen and a model calculation parameter preparation screen, completing all preparatory work before model calculation through two tables, and realizing data import and calculation through model calculation buttons; (2) creation of new plan; (3) preparation of model calculation parameters: extracting all required parameter fields, creating tables, and giving initial values; (4) calculation of the model; (5) Detection and iteration of the experimental results until the model results meet the production requirements. The invention can analyze the existing production system, realizes the development of a simulation system for the existing on-line system through parallel data, ensures that the virtual system has the same parameters, equipment and environment as the on-line system, and facilitates the off-line test of the function.

Description

Technical field: [0001] The invention relates to a method for virtual steel rolling by using historical data, and belongs to the technical field of hot rolling control. Background technique: [0002] Before the implementation of the project, routine production and maintenance issues such as fault finding, function addition, program improvement, and bug inspection in hot rolling production were often unable to be carried out. The phenomena and reasons are as follows: [0003] Fault finding, due to incomplete log records, scattered relevant information, needs to switch back and forth, resulting in long time to find faults, incomplete fault analysis, and potential safety hazards. [0004] For new functions and new product development, repeated tests are required for new functions before they can be put into use. New product development, on-site confirmation and adjustment of thousands of parameter data in model calculation. These tasks are impossible to complete in actual pro...
