Abstract

The invention provides a slab continuous casting secondary cooling and dynamic soft reduction off-line simulation system, which mainly solves the technical problem that the adjustment cost of dynamic soft reduction parameters is too high in actual production. The computer of the simulation system includes: the simulator core unit, which realizes the simulation of the process parameters of the main pouring conditions; the process model parameter setting unit, which is used to set the process and control parameters in the model; the model calculation core unit, combined with Simulate the pouring condition parameters to calculate the process model; the monitoring and display unit mainly completes the interface display of the simulation results; the simulator kernel unit and the model calculation kernel unit realize the interaction of process parameter data through the shared memory, and the model calculation kernel unit and the monitoring display unit pass The Ethernet local area network interacts with the simulation result data, the model calculation core unit and the process model parameter setting unit realize the process model parameter interaction through the model parameter database. The invention is mainly used for simulating the specific control process of secondary cooling water distribution and dynamic soft reduction of slab continuous casting.

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 ...
