Metal lost to oxidation and slag formation during melting.
Invest 30 minutes to build a proper charge calculation sheet. It will pay back in scrap reduction, alloy savings, and consistent quality for every single pour.
: Provides a base with known chemical composition (high in Carbon and Silicon). Steel Scrap
While manual math is educational, modern foundries use faster methods.
Keep below specification limits. Steel scrap can contain residual copper (from wiring). Use clean returns for critical alloys.
Achieving the target chemical composition (e.g., carbon, silicon, manganese) ensures the mechanical properties of the finished part are within specified tolerances.
For each material, you need:
