Reduce Melt Loss AND Reduce Your Carbon FootPrint!

Surface dross generation rates are affected by several factors including: Metal Temperature – Often “dominates the equation” above 730°C (1350°F). Surface Area – Can be moderated by a heavy argon cover gas. Turbulence – Induced by flow and mechanical systems, increases effective surface area. Direct Incorporation – Mechanisms that force gas and dross below the metal …

Reduce Your Carbon Footprint! CIRCULATE

The plot below shows surface and bottom molten metal temperatures before and after about 5 minutes of proper circulation. The bottom and surface temperatures start out with roughly 100C difference. Within 5 minutes of turning on the circulation pump, the temperature uniformity is within a 10C. There are two immediate observations that can be made: …
