The invention relates to a method for the heat treatment of a metallic product (P), in particular a strip or sheet, in which the product (P) is controlled and/or regulated by means of a control and/or regulating device (100) controlled and/or regulated furnace device (110) is carried out at a predetermined speed in a conveying direction (F), the product (P) being heated up to a first point (I) and then up to a second location (H) or is cooled down to a third location (III). The method according to the invention is characterized in that an austenite content of the product P is predicted for the second location (H) or for the third location (III) and it is then checked whether this austenite proportion is within a desired target range, in which case If a deviation from this is found, for example a zone temperature of the furnace device 110 is adjusted and preferably regulated in such a way that the austenite proportion of the product P predicted for the second location (II) or for the third location (III) is within a desired quality window for the target value of the austenite content.

A hot metal gas forming and quenching system and process therefor are provided. The system includes a hydraulic press, a die assembly, a rapid heating module and a rapid cooling module. The die assembly includes a progressive die which can realize the hot gas bulging and rapid cooling of the workpiece. Through the above system and the process, making pipes with uncoated plates has a lower cost than with coated and plated steel plates, with fewer structural defects and process risks. By using a progressive die, a resistance heating process, and hot gas bulging and quenching processes are performed in parallel, and the material is loaded progressively, thereby having a fast pace and a greatly improved efficiency. A heating state of parts is fully protected, oxidation is avoided, and no coating is required. After the workpiece is formed, it can be directly welded to a car body without shot blasting.
