Abstract

The invention provides an off-line simulation system for a secondary cooling of a slab continuous casting under a dynamic slight press, and mainly solves the technical problem that the adjustment of parameters under a dynamic slight press in an actual production costs too much. The computer in the simulation system consists of a simulator inner core unit, which is used for realizing an analog simulation of the main casting condition parameters; a processing model parameter setting unit which is used for setting the processing controls parameters in the model; a model calculating inner core unit, which is used for calculating the processing model combined with the simulated casting condition parameters; a monitoring and displaying unit, which is mainly used for accomplishing an UI display for the simulation result. The simulator inner core unit and the model calculating inner core unit realize an interaction of process parameter data through a shared memory. The model calculating inner core unit and the monitoring and displaying unit conduct an interaction of simulation result data through an Ethernet LAN. The model calculating inner core unit and the processing model parameter setting unit realize an interaction of processing model parameters through a database of model parameters. The invention is mainly applicable to an analog simulation of the specific control process of the water distribution for a secondary cooling of a slab continuous casting under a dynamic slight press.

Description

Technical field: [0001] The invention belongs to the production simulation technical field of metallurgical continuous casting, and in particular provides an off-line simulation system for continuous casting secondary cooling and dynamic soft reduction, which is used for the specific control process of secondary cooling water distribution and dynamic soft reduction in slab continuous casting production simulation simulation. Background technique: [0002] With the development of industrial technology, people have higher and higher requirements for the quality of steel products, such as steel for pipelines for transporting natural gas, steel for offshore drilling, and steel for platform structures, etc., all require high strength, high toughness, excellent welding performance and good resistance. Hydrogen rupturing. Defects such as slab center segregation and center porosity that often occur in the continuous casting process will seriously affect the internal quality of the ...
