Epsilon

Rolling Ingot Casting Technology

The Wagstaff^® Epsilon^™ mold is a robust, user-friendly upgrade from conventional Water Hole Mold ingot technology, engineered to operate at optimized metal levels for improved cast surface quality.  Epsilon's proven performance and practicality have led to steady global adoption as ingot casters recognize the benefits of this technology.

When casting ingots with wide aspect ratios or certain alloys, butt curl control is required for safe and consistent production. The Epsilon mold reduces butt curl, minimizing common defects such as bleed overs, bleedouts, and ingot cracking, thereby enhancing operator safety and process reliability. 

This advantage is achieved through Wagstaff’s SplitJet™ Enhanced Cooling Technology, featuring two water chambers, each equipped with dedicated water spray holes. This design enables a high cooling rate that significantly reduces curl during casting.

Overall, rolling ingots produced with Epsilon technology exhibit less curl, resulting in superior casting quality, less scrap, and increased profitability for producers.
