Abstract
Abstract Improved lubrication of an open-ended mold assembly for casting of molten metal into a solidified metal body. The mold assembly includes a mold surface and has a capillary gap in communication therewith. Lubricant is admitted in controlled amounts to the capillary gap to at least one predetermined location thereof in order to effect improved lubrication about the mold surface during casting of molten metal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
An open ended mold assembly for continuous casting of metal bodies, said assembly comprising a chilled mold section having an interior mold surface extending between a molten metal inlet and a solid metal outlet, a plate element connected to the inlet of said mold section and provided with an opening in communication with the interior of the mold section, an annular slotted gasket interposed between said plate element and said mold section in such manner that the inner peripheral edge of said gasket is offset outwardly of the interior mold surface of said mold section and said gasket and said mold section cooperate with each other to provide at least one lubricant chamber disposed outwardly of the interior mold surface, complimentary portions of said plate element and said mold section acting in conjunction with the inner peripheral edge of said gasket to define a capillary gap extending around the periphery of the interior mold surface at the inlet of said mold section, means for connecting a source of lubricant to said lubricant chamber and a slot in said gasket extending from the inner peripheral edge of said gasket toward the outer periphery thereof to provide a lubricant oil passageway.
Claim 2
Dependent Claim
199 words
An open ended mold assembly for continuous casting of metal bodies, said assembly comprising a chilled mold section having an interior mold surface extending between a molten metal inlet and a solid metal outlet, a plate element connected to the inlet of said mold section and provided with an opening in communication with the interior of the mold section, an annular slotted gasket interposed between said plate element and said mold section in such manner that the inner peripheral edge of said gasket is offset outwardly of the interior mold surface of said mold section and said gasket and said mold section cooperate with each other to provide at least one lubricant chamber disposed outwardly of the interior mold surface, complimentary portions of said plate element and said mold section acting in conjunction with the inner peripheral edge of said gasket to define a capillary gap extending around the periphery of the interior mold surface at the inlet of said mold section, means for connecting a source of lubricant to said lubricant chamber and a slot in said gasket extending from the inner peripheral edge of said gasket toward the outer periphery thereof to provide a lubricant oil passageway.
Claim 3
Dependent Claim
25 words
An open ended mold assembly as set forth in claim 1 including valve means for regulating the rate of lubricant flow to the lubricant chamber.
Claim 4
Dependent Claim
53 words
An open ended mold assembly as set forth in claim 1 in which one dimension of said gap extends about 0.005 of an inch in the axial direction of said mold section and the other dimension of said gap extends about 0.050 of an inch in the transverse direction of said mold section.
Claim 5
Dependent Claim
22 words
An open ended mold assembly as set forth in claim 1 in which said mold assembly is disposed in a horizontal position.
Claim 6
Dependent Claim
22 words
An open ended mold assembly as set forth in claim 1 in which said mold assembly is disposed in a vertical position.
Claim 7
Dependent Claim
233 words
An open ended mold assembly for continuous casting of metal bodies, said assembly comprising a chilled mold section having an interior mold surface extending between a molten metal inlet and a solid metal outlet, a plate element connected to the inlet of said mold section and provided with an opening in communication with the interior of the mold section, an annular gasket member interposed between said plate element and said mold section in a manner that the inner peripheral edge of said gasket is spaced outwardly of the interior mold surface of said mold section and said gasket and said mold section cOoperate to provide at least one lubricant chamber outwardly of the interior mold surface, complimentary portions of said plate element and said mold section in conjunction with the inner peripheral edge of said gasket defining a capillary gap extending around the periphery of the interior mold surface at the inlet of said mold section, and means for connecting a source of lubricant to said lubricant chamber, said gasket being provided with a plurality of slots, each of said slots extending from the inner peripheral edge of said gasket towards the outer periphery thereof, whereby the slots are arranged in alignment with the lubricant chamber in order to provide oil flowing communication from said chamber to said gap so as to supply lubricant to different portions of said gap in varying amounts.
Claim 8
Dependent Claim
233 words
An open ended mold assembly for continuous casting of metal bodies, said assembly comprising a chilled mold section having an interior mold surface extending between a molten metal inlet and a solid metal outlet, a plate element connected to the inlet of said mold section and provided with an opening in communication with the interior of the mold section, an annular gasket member interposed between said plate element and said mold section in a manner that the inner peripheral edge of said gasket is spaced outwardly of the interior mold surface of said mold section and said gasket and said mold section cOoperate to provide at least one lubricant chamber outwardly of the interior mold surface, complimentary portions of said plate element and said mold section in conjunction with the inner peripheral edge of said gasket defining a capillary gap extending around the periphery of the interior mold surface at the inlet of said mold section, and means for connecting a source of lubricant to said lubricant chamber, said gasket being provided with a plurality of slots, each of said slots extending from the inner peripheral edge of said gasket towards the outer periphery thereof, whereby the slots are arranged in alignment with the lubricant chamber in order to provide oil flowing communication from said chamber to said gap so as to supply lubricant to different portions of said gap in varying amounts.
Claim 9
Dependent Claim
24 words
An open ended mold assembly as set forth in claim 6 in which said slots are nonuniformly disposed about the periphery of said gasket.
