Secondary cooling control model based on effective-speed and effective-superheat in continuous casting

A secondary cooling control model based on effective-speed and effective-superheat was developed to solve the problem of the frequent fluctuations of casting speed and temperature,which can lead to great fluctuations of slab surface temperature under secondary cooling control.The new model can well control the surface temperature of slabs without on-line calculating the temperature values,while it only needs on-line calculating the values of effective-speed and effective-superheat by existing parameter control models.Computer simulation indicates that this control model has good adaptability to the variation of casting speed and superheat,meets the requirements of modern continuous casting production and can be operated simply and conveniently.
