Open Mould Ingot Casting

Air or water cooled

Hertwich R&D has taken on the challenge of designing a much improved caster. The new design meets longtime existing customer demands and comes with some clear advantages such as an easier to control melt supply and pouring system as well as water-free cooling during the metal solidification phase.

Water-cooled ingot caster

In countries with a hot climate, water cooling is vital to achieve the diessired production rate. Open-mold ingot casters are traditionally water cooled as a cheap and simple way to solidify liquid metal.

Air-cooled ingot caster

You can also freeze and cool ingots exclusively with air. Here are your benefits compred with water cooling.

Better ingot quality
No shrink holes or cavaties, hazard-free remelting
No hydrogeen pick-up
Less wear, longer mold service life
Less maintenance
No foundation pit
No water infrastructure
Additionally primary cooling of filled molds, secondary cooling of ingots in a paternoster-type cooling tower
