<p>PROBLEM TO BE SOLVED: To provide a residual deposit removing method capable of more reliably removing a deposit left in a hot forging mold after a hard-to-work material such as Ti alloy or Ni-based super-heat-resistant alloy is hot-forged.SOLUTION: A residual deposit removing method for a hot-forging mold or a method using a hot-to-work material as a material for removing a residual deposit having been hot-forged, comprises: a heating step of heating and solidifying a deposit left in the hot forging mold; and a lubricant removing step of blowing dry ice particles onto the heated residual deposit by a high-pressure gas, and removing the deposit.</p> |
