Fast Casting of 150sq Billets-Boost of Productivity
In 2010 Tung Ho commissioned a 5 strand billet caster with direct hot charge link to the rolling mill via an induction heater.In order to increase the productivity of the caster with minimum investment,substantial trials to increase the casting speed have been carried out.The trials were conducted on the section 150mm sq.The following key equipment was installed to cope with the high casting speed: Newly developed mould tubes,Adapted foot rolls,Modified secondary spray cooling,Mould electromagnetic stirring and auxiliary withdrawal unit.In this paper the following achievements will be presented: Presentation of the fast casting concept and already implemented modification in engineering and equipment; Presentation of already achieved results with casting speed up to 5.6m/min (57t/h per strand) and long term operation casting speed of 4.7m/min (48t/h per strand); Presentation of quality achieved at these speeds; Presentation of further modifications that are currently on-going to further increase casting speed and throughput with the aim to stabilize production at 50t/h and to allow long term operation casting at 6m/min and above.
