Wagstaff AirSlip - Billet Casting System

The AirSlip process uses an optimized mold length, faster casting speed, individual water jets and a unique air-cushion to minimize heat extraction through the mold and enhance secondary cooling. The direct chill (DC) casting process extracts heat through two mechanisms: first through the mold wall as the molten metal contacts it, and secondly through direct contact (or “direct chill”) with a specifically designed water pattern as the semi-solidified billet exits the mold. 

Very little mold cooling occurs with AirSlip mold technology, leaving the majority of the heat extraction to direct water quench. This leads to a shallow sump and a very thin-shelled, uniform-grained billet with excellent surface smoothness and high pit recoveries for casters.

• AirSlip® billet is the world standard for quality

• Patented DualJet™ Enhanced Cooling Technology provides optimal cooling performance

• Enhanced mold geometry dramatically increases cooling rate

• Robust construction - The AirSlip mold is precision machined from a single piece of aluminum

• Fast casting speeds and low maintenance

• Faster extrusion speeds resulting from small shell zone

• Environmental benefits:

  • Minimal oil consumption reduces the need for expensive, complex oil cleaning systems
  • Minimal water use reduces plant water system costs
  • Shorter homogenization cycle reduces energy consumption
