Abstract
A continuous lubrication casting mold for use in a process of continuously casting molten metals and alloys wherein a parting and/or lubricating agent reservoir is provided in the mold body. The agent is continuously applied over the inner surface of the mold after being introduced through passages within or through the mold section. The lubricant passages may be an intrinsic characteristic of the mold material or may be provided in the form of feed holes through the mold section. The ability to transmit lubricant through to the internal surface of the mold can be varied within the length of the casting mold to provide for variable lubricant transfer rates to different parts of the casting surface.
Claims4
A casting apparatus for continuously casting molten metals or alloys comprising:
- a continuous lubrication casting mold, said casting mold including a permeable casting mold section having an inner casting surface, a molten metal or alloy inlet end and an outlet end;
- said permeable casting mold section comprising a porous body having a continuous open pore fraction associated therewith for establishing passages for lubricant, said open pore fraction of said casting mold section varying along the length thereof so that said open pore fraction of said casting mold section is larger at said molten metal or alloy inlet end of said casting mold section as compared to said outlet end of said casting mold section;
- and
- means for supplying lubricant to said permeable casting mold section along substantially its entire length whereby lubricant continuously transfers onto said inner casting surface along substantially the entire length thereof.
A casting apparatus for continuously casting molten metals or alloys comprising:
- a continuous lubrication casting mold, said casting mold including a permeable casting mold section extending substantially the entire length of said mold and having an inner casting surface, a molten metal or alloy inlet end and an outlet end, the thickness of said casting mold section varying along the length thereof so that the thickness of said casting mold section is less at said molten metal or alloy inlet end of said casting mold section as compared to said outlet end of said casting mold section;
- and
- means for supplying lubricant to said permeable casting mold section along substantially its entire length whereby lubricant continuously transfers onto said inner casting surface along substantially the entire length thereof, said permeable casting mold section comprising a porous body having a continuous open pore fraction associated therewith.
A mold for continuous casting of molten metals or alloys including a permeable casting mold section having an inner casting surface, wherein said permeable casting mold section is characterized by having a varying permeability along substantially the entire length thereof;
- said permeable casting mold section comprising a porous body having a continuous open pore fraction associated therewith which varies along the length of said casting mold section so that said open pore fraction of said casting mold section is greater at the molten metal or alloy inlet end of said casting mold section as compared to the outlet end of said casting mold section.
A mold for continuous casting of molten metals or alloys including a permeable casting mold section having an inner casting surface, a molten metal or alloy inlet end and an outlet end wherein said permeable casting mold section extends substantially the entire length of said mold and is characterized by having a varying permeability along substantially the entire length thereof;
- said permeable casting mold section comprising a porous body having a continuous open pore fraction associated therewith;
- and the thickness of said casting mold section varying along the length thereof so that the thickness of said casting mold section is smaller at the molten metal or alloy inlet end of said casting mold section as compared to the outlet end of said casting mold section.
