Impact of the Tundish Metal Wiring Geometry and Casting Process Parameters on the Running of Billet Continuous Casting Machine

Abstract

Stable running of the billet continuous casting machine (CCM) in the first place implies a correct startup of all casting strands. The challenge of the strands startup lies not only in commonly known facts, but also in insignificant details. The paper describes the impact of the tundish metal wiring geometry and starting process parameters of CCM as well as solutions for startup overflows and startup breakouts under the mould in the billet CCM. The paper is written on the basis of the author’s own experience in the integration of the nozzle casting in the billet CCMs in OJSC “ChMP” and OJSC “PNTZ”.
