METHOD FOR PRODUCING PACKAGING STEEL |
摘要 |
The invention relates to a method for producing packaging steel consisting of a cold-rolled steel sheet made of unalloyed or low-alloy steel having a carbon content of less than 0.1%. In order to provide high-strength packaging steel that has good formability and high corrosion resistance and can be produced in as energy-saving a manner as possible, the steel sheet according to the invention is first coated with a metallic coating and then annealed in a recrystallising manner at a heating rate of more than 75 K/s and preferably more than 100 K/s to temperatures of more than 700° C., such that the metallic coating melts. The coated and annealed steel sheet is then quenched to normal temperature at a cooling rate of at least 100 K/s. |
