Homogenization Aspects, Continuous versus Batch in an Integrated Modern Casthouse

Abstract:

Article Preview

Continuous homogenizing for extrusion billets has become the accepted standard and state of the art technology. Hertwich Engineering (HE) has, to date, built more than 120 such plants worldwide, which are processing some two thirds of the worldwide extrusion billet production. Batch type homogenizing is still the best suited technology for various alloys which require long holding times, e.g. 4 – 12 hours, as well as for large-only log diameter production. Again, HE has in recent years supplied several batch homogenizing plants. Topics: • Process technology, heating, holding, different types of coolers • New log support saddle design, exit car, no rolling of logs with focus to good billet surface finish • Automated sawing, packing • High efficiency batch furnace and cooler with reversing air and precise temperature regime
