Process and plant for the manufacture of hot rolled biphasic steels

摘要

"PROCESS AND INSTALLATION FOR THE MANUFACTURE OF HOT-LAMINATED STATE BIPHASIC STEELS". In order not to depend on the manufacture of biphasic steels (2), which are fabricated after the last deformation step in a final cooling mill (1) by determined cooling, wherein a biphasic structure of 70 to 90% ferrite and 30 is adjusted. At 10% martensite, steel geometry and strip speed, it is recommended according to the invention to cool down a cooling segment (6) with water cooling steps (7) arranged successively in the form of a light cooling.
