Abstract (en)
[origin: US4463795A] The cooling of a cast steel slab in a continuous casting installation is controlled by dividing the cast product into successive fictitious elements and periodically calculating the water flow values of the cooling water delivered to the successive cooling sections in the secondary cooling zone of the installation as a function of the age of the elements in these sections. The quantity of heat extracted in the mold is taken into account by periodically determining the water flow values in the different zones by means of a computer on the basis of a first curve giving the variations of the quantity of heat extracted from a unitary mass of the cast product as a function of the time while the cast product passes from the point of emergence from the mold to at least the zone of solidification, and a second curve giving the variations of the surface temperature of the cast product during this passage as a function of time. Before each calculation of the water flow values, the first curve is corrected in direct dependence on the quantity of heat extracted from the product in the mold.
