Abstract (en)
[origin: WO2011009769A1] The invention relates to a method for hot forming steel parts, particularly blanks or semi-finished products made of steel, wherein the steel parts are heated in a furnace to a temperature above the Acl temperature to at least partially austenitize and are hot-formed in a forming tool. The aim of providing a method for hot forming steel parts, which makes it possible to carry out the hot forming operation in an energy-efficient manner and at the same time reduces the cycle times for producing a hot-formed component, is achieved by using the waste heat of the furnace for other heat treatment steps of the steel part and/or after the at least partial austenitizing of the steel part.
