Method for producing a molded part having at least two structure zones with different ductilities

The method involves conveying a succession of hardenable steel blanks having regions through furnace (2) such that blanks reach an outlet of furnace with each both of respective regions heated to austenitization temperature. The blanks are positioned with regions (5) in the chamber of holding unit (...

Beschreibung
Zusammenfassung:	The method involves conveying a succession of hardenable steel blanks having regions through furnace (2) such that blanks reach an outlet of furnace with each both of respective regions heated to austenitization temperature. The blanks are positioned with regions (5) in the chamber of holding unit (7) and regions (4) outside the chamber. The regions (5) are heated and maintained at temperature and regions (4) are cooled with air to temperature at which microstructures become ferritic-pearlitic while holding the regions inside and outside the chamber. An independent claim is included for apparatus for making shaped object with different ductility and microstructures from semi-finished portions.
