ABSTRACT:
The machine for semicontinuous casting of metals comprises a rack-and-gear drive for withdrawal an ingot and for moving a carriage fitted with a dummy bar along a vertical column. The racks of said drive are fixed on said carriage and the gear wheels with a pitch approximating the length of said racks are disposed along said column. The initial weight of said carriage fitted with the dummy bar exceeds slightly the initial force required for withdrawal of the ingot from the mold. To maintain constant operating conditions for the driving electric motor of the ingot withdrawal gear, provision is made for a ferromagnetic powder brake whose exciting winding is coupled with an ingot length sensor and whose control winding is coupled with an ingot withdrawal force sensor.
