METHOD AND CONTINUOUS CASTING AND ROLLING PLANT FOR SEMI-ENDLESS OR ENDLESS ROLLING BY CASTING A METAL STRAND, ESPECIALLY A STEEL STRAND, WHICH IS CUT TO LENGTH AS REQUIRED AFTER SOLIDIFICATION

摘要

The invention relates to a method and casting roller plant for the semi-endless orendless rolling by casting of a metal, in particular a steel strip (1a), whichmay betransversely separated as required after solidification. The casting strippart lengths (20)are fed to a roller furnace (2) for heating and equilibration at the rollingtemperature andthe partial lengths (20) for rolling out are fed to a rolling train (3) forrolling, whereby thestrip casting is continued uninterrupted during the rolling operation.According to theinvention, a closer matching of the strip casting and the rolling can becarried out,whereby the casting speed (Vc) is reduced for roller change such that betweenthe endof rolling a preceding multiple length (21) and the insertion of a new partiallength (20)or multiple lengths (21) into the rolling gear a sufficient buffer time for aroller exchangeis provided.
