Abstract: A multipurpose continuous processing line able for heat treating and hot dip coating a steel strip containing: an annealing section (1) for heating the steel strip to a predetermined annealing temperature and for maintaining the steel strip at said annealing temperature, a first transfer section (2), an overaging section (3) able to maintain the temperature of the steel strip between 300° C. and 700° C., a second transfer section (4) able to adjust the temperature of the steel strip to allow the hot dip coating of the strip and, a hot dip coating section (5), wherein the first transfer section (2) includes, in sequence, a cooling section (21) and a heating section (22).

Abstract: The invention relates to a method for producing a high strength coated steel sheet having a yield stress YS>550 MPa, a tensile strength TS>980 MPa, and improved formability and ductility. The steel contains: 0.15%?C?0.25%, 1.2%?Si?1.8%, 2%?Mn?2.4%, 0.1%?Cr?0.25%, Al?0.5%, the balance being Fe and unavoidable impurities. The sheet is annealed at a temperature between TA1=Ac3?0.45*(Ms?QT) and TA2=830° C. for at least 30s then quenched by cooling it to a quenching temperature QT between 180° C. and 300° C., then heated to a partitioning temperature PT between 380° C. and 480° C. and maintained at this temperature for a partitioning time Pt between 0 sec and 300 sec, then either hot dip coated and cooled to the room temperature with a cooling rate of at least 25° C./s below 300° C., or directly cooled to the room temperature with a cooling rate of at least 25° C./s and further electro-galvanized, or cooled to the room temperature with a cooling rate of at least 25° C./s without coating.

Abstract: The disclosure concerns X-ray tubes. To obtain greater temperature stability of an X-ray tube, a substance is placed in the circulation space of the cooling fluid of the tube. The latent heat of fusion of this substance is used so that it melts during the examination stage in absorbing heat, and gets solidified during the resting stage. The disclosure is applicable to X-ray tubes.
