Modelling of a casting-rolling assembly

摘要

The method involves pouring metal having temperature (T) into casting device having mold region. The contact time (t2) and per unit time from respective current limiting elements are inputted per rotation element of cycle time. Each strand shell thickness (dS) is determined based on rotational speed of surface elements. The local temperature (T') of metal strip is determined based on mold region temperature, and mold region thickness (d) is determined based on shell thickness. The determined local temperature and mold region thickness are considered for further use by computer (11). Several side current limiting elements which are surface elements are provided in several mold regions. Each rotation element is moved with a respective rotational speed in cyclic state along respective orbit. The surface elements are dipped on a respective insertion point in the mold region. The metal is solidified to respective strand shell during the further forward movement of the surface elements. The metal strip at the trigger point is withdrawn from the mold region. The strand shells are constituents of the metal strip. Independent claims are included for the following: (1) computer program for primary investigation of thickness and temperature of cast metal strip.
