Abstract

A system for controlling the progress of the manufacture of at least one product by vertical semi-continuous direct chill casting, in particular from aluminium alloy, in a fixed mold, the control system includes a dummy bottom configured to form a movable lower bottom of the fixed mold and to carry the product during casting; a weighing cell, on which the dummy bottom is arranged to rest, the weighing cell being configured to take measurements representative of the mass of the product carried by the dummy bottom during casting; and a support of the dummy bottom, to which the weighing cell is linked, configured to lower the false bottom relative to the fixed mold, substantially in a vertical direction, during casting; and a processing unit connected to each weighing cell, and configured to process the measurements, and calculate the variation in the mass of the product over time.

Dependent claims

A system for controlling the carrying out of the manufacture of at least one product by vertical semi-continuous casting, with direct cooling, in a fixed mold, said control system comprising:

at least one bottom block configured to form a movable bottom base of the fixed mold and to carry the at least one product, during casting,
at least one weighing cell, on which the at least one bottom block is disposed in abutment, the at least one weighing cell being configured to take measurements representing the mass of the at least one product carried by the at least one bottom block during casting,
a bottom block support, to which the at least one weighing cell is connected, configured to lower the at least one bottom block with respect to the fixed mold, substantially in a vertical direction, during casting, and
at least one processing unit connected to the at least one weighing cell, and configured to process the measurements, to calculate the variation in mass of the at least one product over the course of time.
