Continuous casting apparatus for aluminum onto metallic strip material

Claim 1

IN AN APPARATUS FOR CONTINUOUSLY CASTING AND BONDING MOLTEN ALUMINUM OR ALUMINUM ALLOYS AT A TEMPERATURE OF ABOUT 1350* F. ONTO HORIZONTALLY MOVING METAL STRIP MATERIAL, THE COMBINATION OF: A BOTTOM DIE MEMBER OF HEAT AND THERMAL SHOCK RESISTANT MATERIAL HAVING AN OPENING IN ONE END THEREOF, SPACED APART BOTTOM RAILS MOUNTED ON SAID BOTTOM DIE MEMBER ADJACENT SAID OPENING FOR SUPPORTING THE MOVING METAL STRIP TO CLOSE THE TOP OF SAID OPENING: A POURING BOX; A TOP DIE MEMBER OF HEAT AND THERMAL SHOCK RESISTANT MATERIAL MOUNTED ABOVE SAID BOTTOM DIE MEMBER AND UNDERNEATH SAID POURING BOX, SPACED APART TOP RAILS CONNECTED TO SAID TOP DIE MEMBER FOR ENGAGING THE UPPER SURFACE OF SAID MOVING METAL STRIP OPPOSITE THE LOCATION WHERE THE BOTTOM RAILS ENGAGE THE BOTTOM OF THE STRIP, SAID TOP DIE MEMBER HAVING A RECESSED CAVITY IN ITS UNDERNEATH SURFACE ADJACENT THE PATH OF SAID METAL STRIP AND HAVING A CASTING OPENING THERETHROUGH COMMUNICATING WITH SAID POURING BOX, A SIZING DIE MEMBER OF HEAT AND THERMAL SHOCK RESISTANT MATERIAL AND RESISTANT TO CHEMICAL REACTION WITH THE MOLTEN MATERIAL MOUNTED IN THE RECESSED CAVITY OF SAID TOP DIE MEMBER, SAID SIZING DIE MEMBER HAVING A CASTING OPENING REGISTERING WITH THE CASTING OPENING IN SAID TOP DIE MEMBER AND EXTENDING TO A LOCATION ADJACENT THE TOP SURFACE OF SAID METAL STRIP AS THE METAL STRIP MOVES FORWARD THROUGH THE DIE FOR APPLYING MOLTEN METAL FROM THE POURING BOX TO THE MOVING METAL STRIP, SAID SIZING DIE MEMBER HAVING A CAVITY IN ITS UNDERNEATH SURFACE OF THE APPROXIMATE THICKNESS OF THE METAL TO BE CAST ON THE STRIP FOR LIMITING THE AMOUNT OF MOLTEN METAL DEPOSITED ON THE MOVING STRIP AND HAVING A PORTION EXTENDED IN THE FORWARD DIRECTION OF MOTION OF THE METAL STRIP PARALLEL TO SAID STRIP AND SPACED FROM SAID STRIP BY THE APPROXIMATE THICKNESS OF THE METAL TO BE CAST IN TEH STRIP; QUENCHING MEANS MOUNTED A SUBSTANTIAL DISTANCE BELOW SAID STRIP AND IN A LINE ACROSS THE STRIP AND COMPRISING ONE OR MORE NOZZLES DIRECTED UP INTO THE SAID OPENING IN THE SAID BOTTOM DIE MEMBER AND ADAPTED TO DIRECT COOLING FLUID AGAINST THE UNDEREATH SURFACE OF SAID MOVING STRIP AT A LOCATION IMMEDIATELY FORWARD OF THE LOACTION OF THE CASTING OPENING AND BENEATH THE EXTENDED PORTION OF THE SIZING DIE MEMBER WHEREBY MOLTEN METAL CAST UPON THE TOP SURFACE OF THE STRIP IS QUENCHED WHILE IT IS IN AN ENCLOSED COMPRISED OF SAID TOP, BOTTOM AND SIZING DIE MEMBERS AND SAID TOP AND BOTTOM RAILS SUBSTANTIALLY TO PREVENT CHEMICAL REACTION BETWEEN SAID MOVING METAL STRIP AND SAID CAST METAL.
