Process for producing a hot-formable steel flat product

摘要

The invention relates to a method for producing a hot-formable flat steel product, comprising: a production step (10) for producing a cold-rolled tempered steel flat product; a heating step (20) for heating the tempered steel flat product; and a coating step (30) for coating the heated temper steel flat product using a hot dip process. In order to reduce the energy consumption for the production of hot-formable flat steel products, the tempering steel flat product is heated in the heating step (20) to a maximum temperature which is greater than or equal to a temperature of a melt bath used in the hot-dip process and less than an austenitizing temperature of the cold-rolled heat-treated steel flat product, and the tempered flat steel product heated in the heating step (20) is supplied to the coating step (30) without an intermediate step or after the temperature of the tempered steel flat product has been adjusted to a coating temperature.
