ELECTROMAGNETIC APPARATUS FOR CONSTRICTION OF LIQUID METALS

摘要

IN THE CANADIAN PATENT AND TRADEMARK OFFICE PATENT APPLICATION entitled "ELECTROMAGNETIC APPARATUS FOR CONSTRICTION OF LIQUID METALS " IN THE NAME OF : AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE (ANVAR) The invention relates to the constriction of liquid metals at the outlet of an orifice. The jet 6 of liquid metal leaves an orifice 1 forming a nozzle of diameter D and it is constricted into a jet 9 of diameter d due to a winding 2 traversed by an alternating current and a conductive screen 3 penetrating into the interior of the winding 2. Application to the flow of steel for forming billets or wires and to passage past joints ; application to the flow of aluminum, copper and their alloys for forming wires or billets of small diameter.
