Preparation process for al - si - coated steel parts and al - si - a coated sheet steel tape

摘要

A method for producing a component (5) consists of a with an al - si - coating coated sheet steel tape (1), said method comprising the steps of:– a with an al - si - precoating the coated sheet steel tape (1) is subjected to a first heating step, wherein the temperature and the duration of the heat treatment in the case of the first heating step are adjusted so that the al - si - coating completely with iron of the steel is become shorted– and the by alloyed sheet steel tape (6) is temporarily stored and– the heat-treated, by means of alloyed sheet steel tape (6) according to the intermediate storage to a sheet metal blank (4) is cut,– the sheet metal blank (4), in a second step of heating at least in some regions, to a above the ac1 - temperature heating temperature lying heated, in which the sheet metal blank at least in some regions, an at least part of austen table structure,– the at least regionally to the heating temperature heated sheet metal blank (4), to the component (5) and deformed– the resulting component (5) is controlled is cooled and, at least in some regions, a hardness structure.
