METHOD OF SUPERCOMPACT PRODUCTION OF ENDLESS HOT STRIP ON CONTINUOUS-REVERSING CASTING-ROLLING UNIT Russian patent published in 1997 - IPC

FIELD: production of endless hot strip on continuous-reversing casting-rolling unit. SUBSTANCE: the offered method includes continuous casting of metal into thin slab; accumulation and heating of slab, its reversing rolling into endless strip by successive sections for several passes with return of rolled section to zone of accumulation; cooling of rolled strip, cutting and coiling. After each pass, except for the last, rolled section is simultaneously heated and accumulated. Accumulation is effected by two-inlet coiling into intermediate roll with its simultaneous motion in direction of production process flow of metal. In course of return of strip, roll is uncoiled with simultaneous motion against metal flow. After the last pass, rolled section of strip is simultaneously accumulated and heat-insulated between zones of heating-accumulation of rolled section of strip and cooling. Further on, for the cycle of rolling of the next section of slab, rolled section of strip is continuously fed to cooling zone. EFFECT: higher efficiency. 2 cl, 19 dwg, 2 tbl
