CONTINUOUS GREASE LUBRICATION SYSTEM FOR METAL CASTING MOULDS

摘要

A lubricating system is described for continuous grease lubrication of a casting mould surface. The mould is one for effecting solidification of molten metal into a formed metal product including means adjacent to an inlet portion of said mould for feeding said molten metal into the mould and means for delivering a lubricating grease to a surface of said mould contacting the molten metal to substantially prevent adhesion of any solidified metal on said surface. It has a lubricating grease delivery system comprising at least one grease delivery channel arranged generally parallel to the mould surface, inlet means for delivering a flow of grease into said channel, a plurality of uniformly spaced restrictive flow passages extending across between said delivery channel and grease outlet holes adjacent the molten metal for delivery of grease to the mould surface, and means for feeding grease in either solid or liquid form to said delivery channel.
