METHOD AND PRODUCTION LINE FOR PRODUCING HOT ULTRATHIN STEEL STRIP WITH TWO CASING LINES FOR ONE CONTINUOUS ROLLING LINE

摘要

FIELD: process engineering.;SUBSTANCE: production line comprises two lines (a, b) for casting thin slabs of thickness lower than or equal to 100 mm. Only one line (a) is connected with rolling line (e, g) incorporating two mutually adjustable pairs of furnace downcoilers (A1, A2, B1, B2), each in one casing line. It comprises also bypass section (d) between two furnace downcoilers (A1, A2) to allow continuous feed of finishing rolling mill stand (g). Note here that there is transverse section (k) operated in production of a lot of products for transfer of said pair of furnace downcoilers (B1, B2) from casing line (b) into line (a). Note also there is induction furnace (f) arranged downstream of said downcoilers with drums and immediately ahead of finishing rolling stand (g). Proposed method uses appropriate process procedures.;EFFECT: ease of production, expanded performances of equipment for production hot-rolled strip.;9 cl, 4 dwg
