Abstract In apparatus which is particularly adapted for continuous casting in a horizontal direction lubrication is provided by feeding a lubricating material to the peripheral edge of the entrance end of the mold cavity and applying a pulsating vacuum at the periphery of the exit end of the mold cavity. Structure producing a venturi effect is utilized for producing the vacuum. Molten metal from a supply is fed to the mold cavity through a feed spout extending into a duct of refractory material which is connected to the entrance of the mold cavity. Heat is applied to metal in the duct for melting metal which has solidified on the end of the feed spout and for keeping the metal molten in the duct. The high heat required is suitably applied by induction heating coils around the duct.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
In a continuous casting method wherein molten metal fed into the entrance end of an open-ended mold cavity peripherally solidifies to form a strand which is withdrawn from the other, exit, end of the cavity, a method of lubricating the interface between the wall of the mold cavity and metal therein comprising: feeding a lubricating material to the peripheral edge at the entrance end of the mold cavity, creating a vacuum at the exit end of the mold cavity between the wall of the mold cavity and the periphery of a strand therein for removing gases from the mold cavity and for drawing said lubricating materiaL into the mold cavity, and pulsating said vacuum, said lubricating material being a flux material.
Claim 2
Dependent Claim
