Abstract
A method for removing foreign material such as paints and coatings from workpieces using a mobile furnace. The workpieces are flash heated so that only the surface is heated to remove the coatings without heating the core of the workpieces. Deformation of the workpiece and degradation of the thermal treatment of the workpiece material is thereby avoided.
Claims9
A method for removing foreign material from a workpiece, comprising:
- providing a furnace;
- placing said workpiece which has thermal treatment parameters which are changed by heating within said furnace;
- and
- flash heating said workpiece in said furnace for a time period and at a temperature so as to prevent thermal migration between a surface of said workpiece and a core of said workpiece and to heat said foreign material so as to remove said foreign material while preventing deformation of said workpiece, preventing metallurgical changes and preventing degradation of thermal treatment parameters of said workpiece.
