Apparatus for the lubrication of hot head continuous casting molds

Apparatus for continuously casting molten metal comprising:

• a mold having a longitudinal axis, an inner, axially extending wall defining a mold cavity, and an upper surface;
• a hot head member formed of a heat insulating material having a first portion extending transversly over at least a part of said mold cavity, at least part of said hot head member being contiguous with a surface of said mold, said first portion and axially extending mold wall together with a fluctuating level of molten metal during continuous casting of metal in said mold funtioning to define a variable volume cavity,
• a liquid reservoir defined in said mold for holding a separating or lubricating agent;
• and
• a fluid path communicating between said reservoir and said mold cavity across at least a portion of the interface between said mold and hot head member and around the periphery of said mold, said fluid path opening into the upper half of said liquid reservoir so as to prevent gravity flow of liquid from at least the lower half of said reservoir to said mold cavity, whereby periodic pressure changes within said variable volume cavity are utilized for pumping said separating or lubricating agent from said reservoir to the mold cavity.
