PARTIAL RADIATION HEATING METHOD FOR PRODUCING PRESS HARDENED PARTS AND ARRANGEMENT FOR SUCH PRODUCTION

The present invention relates to a method, and system for performing such method, for producing a press hardened part (2′) of heat treatable material having zones of different structure by partially heating a blank (2) before the blank is processed. The method (100) comprises the steps of arranging...

Zusammenfassung:	The present invention relates to a method, and system for performing such method, for producing a press hardened part (2′) of heat treatable material having zones of different structure by partially heating a blank (2) before the blank is processed. The method (100) comprises the steps of arranging (104) the blank in a furnace (10) for heating the blank to a temperature equal to or above the austenitization temperature of the material of the blank to get the blank into an austenitic phase, in a IR heating station (10) partially heating (106), by means of IR radiation (24), at least one first zone (2a) of the blank thereby keeping the at least one first zone of the blank in the austenitic phase, and arranging (108) the blank in a processing unit (30) for forming and quenching the blank to a press hardened part.
