Method for producing a completely or partially enameled component

Abstract

A method for producing an at least partially enameled component shall enable a particularly high product quality with a particularly low energetic expenditure and a low environmental load. For this purpose, according to the invention, a workpiece ( 2 ) carrying an enamel powder is inductively heated, the operating frequency of the inductor ( 4 ) being chosen, in view of the material properties of the workpiece ( 2 ), such that the electromagnetic depth of penetration into the workpiece ( 2 ) is at most 1 mm.

1 . A method for producing a completely or partially enameled component, wherein the workpiece ( 2 ) carrying an enamel powder is inductively heated, the operating frequency of the inductor ( 4 ) being chosen, in view of the material properties of the workpiece ( 2 ), such that the electromagnetic depth of penetration into the workpiece ( 2 ) is at most 1 mm. 
     
     
         2 . The method of  claim 1 , wherein an operating frequency of at least 300 kHz is chosen for the inductor ( 4 ). 
     
     
         3 . The method of  claim 2 , wherein a defective enamel layer already present on the workpiece ( 2 ) is repaired by means of the inductive heating. 
     
     
         4 . The method of  claim 3 , wherein a power density of at least 10 kW/cm 2  is inductively transferred to the workpiece ( 2 ) via the inductor ( 4 ). 
     
     
         5 . The method of  claim 2 , wherein a power density of at least 10 kW/cm 2  is inductively transferred to the workpiece ( 2 ) via the inductor ( 4 ). 
     
     
         6 . The method of  claim 1 , wherein a defective enamel layer already present on the workpiece ( 2 ) is repaired by means of the inductive heating. 
     
     
         7 . The method of  claim 6 , wherein a power density of at least 10 kW/cm 2  is inductively transferred to the workpiece ( 2 ) via the inductor ( 4 ). 
     
     
         8 . The method of  claim 1 , wherein a power density of at least 10 kW/cm 2  is inductively transferred to the workpiece ( 2 ) via the inductor ( 4 ).
