Abstract
The method for the heat treatment of a steel reinforcing element (F) for a tire comprises a transformation of the steel microstructure and in which the temperature of the reinforcing element (F) is reduced during the transformation of the steel microstructure by simultaneously extracting heat from the reinforcing element (F) and supplying heat to the reinforcing element (F).
Claims22
A method for the heat treatment of a steel reinforcing element for a tire, comprising:
- transforming the steel microstructure, said transforming comprising a step of:
- reducing a temperature of the reinforcing element during the transformation of the steel microstructure in a cooling device having a heat extractor, the heat extractor having an inlet (40) at an entry end of the heat extractor, and an outlet (42) located at an exit end of the heat extractor, the cooling device further having two electrically conductive terminals (36, 38), respectively positioned upstream and downstream of the inlet (40) and the outlet (42), by:
- extracting heat from the reinforcing element within the cooling device by the heat extractor arranged within the cooling device while simultaneously supplying heat to the reinforcing element within the cooling device by application of Joule effect heating to the reinforcing element between the two electrically conductive terminals (36, 38).
