Scrap Metal Recycling, Electric Induction Furnace Foundry & Non-Ferrous Smelting ERP: Radiation/Scale Intake, Charge-Mix Chemistry (Spectrometer OES), Slag Loss, and Scrap Metal Council Compliance

Scrap metal recycling yards, ferrous cast-iron/steel foundries, and non-ferrous secondary smelters (remelting HMS 1&2 steel scrap, cast iron, copper millberry/candy, brass, aluminium tense/taint-tabor, and lead-acid battery plates) operate under strict regulatory scrutiny under the Scrap Metal Act (No. 1 of 2015) and intense metallurgical cost pressure. Without automated controls, yards lose money to inflated weighbridge tickets containing dirt, water, or sealed hollow-vessel ballast, costly ferro-alloy (FeSi, FeMn, FeCr) over-additions in the induction furnace, and unrecorded melting oxidation/slag loss.

At devManue, we engineer specialized Scrap Metal Recycling, Induction Furnace Foundry & Secondary Smelting ERP platforms that enforce statutory Scrap Metal Council seller KYC and camera weighbridges, least-cost furnace charge-mix optimization, Optical Emission Spectrometer (OES) bath-chemistry correction calculations, and billet/ingot/casting yield reconciliation.

1. Securing Scrap Yard Intake & Induction Furnace Melt Shop Economics

• Statutory Scrap Metal Act KYC & Multi-Camera Weighbridge Deduction: Before a weighbridge ticket can be generated, the ERP captures the supplier’s ID/CR12, Scrap Metal Council license number, vehicle registration, and overhead IP-camera snapshots of the open truck bed—preventing purchase of restricted critical infrastructure materials while applying inspector-graded dirt, oil, attachment, or moisture tare deductions (e.g., 3%–8%).
• Least-Cost Charge-Mix & OES Spectrometer Bath Trim Calculator: When a furnace operator taps a molten bath sample and runs it on the Optical Emission Spectrometer (%C, %Si, %Mn, %P, %S, %Cr, %Ni, %Cu), our ERP calculates the exact kilogram addition of ferro-alloys or pure sweetening metal needed to bring the heat into ASTM/BS/KEBS specification at minimum cost.
• Melting Oxidation, Dross/Slag & Foundry Risers/Runners Loop: Tracks metallic yield from cold scrap charge to poured ingots, billets, or sand-cast components, recycling internal foundry runners, risers, and skull back into subsequent heats.

2. Spectrometer Bath-Chemistry Ferro-Alloy Trim & Metallic Recovery Engine

Our foundry melt-shop engine calculates the exact ferro-alloy addition required when an induction furnace lollipop sample falls below target specification, taking into account element recovery efficiency in the molten bath:

3. Wooden/Resin Pattern Registry, Sand Moulding & Machining Job Cards

For jobbing foundries casting mining wear parts (crusher jaws, mantles, mill balls), sugar-mill rollers, municipal manhole covers, and pump impellers, the ERP tracks customer pattern storage bays, furan/green-sand resin catalyst ratios, heat-treatment furnace cycles, and CNC machining tolerances.
