Long-term users cite consistent calculations, repeatable quality and better control of alloy additions.

The production risk

Manual calculation is vulnerable under pressure.

In many foundries, charge preparation still depends on operator experience, spreadsheets and repeated correction cycles. That workflow becomes fragile when scrap chemistry, alloy prices, charge masses and shift teams keep changing.

Fluctuating scrap chemistry and alloy prices.
Changing charge masses and multiple products.
Shift changes requiring repetitive calculation logic.
Wrong calculations can lead to unnecessary alloy consumption, delayed pours and rejected melts.
The deterministic solution

Configured metallurgical logic - not guesswork.

ChargeCalc uses product limits, source-material data, source/product yield factors and actual OES analysis to provide a structured calculation environment where identical input conditions produce identical, documented behaviour.

Improve repeatability

Give operators, metallurgists and QC a shared calculation workflow independent of individual experience.

Reduce avoidable cost

Use source materials more intelligently by calculating masses against exact chemistry targets and cost assumptions.

Support charge and melt traceability

Connect charge planning, OES analysis, correction decisions and final production documentation.

Connecting the decision chain

Built for production, metallurgy and QC.

Management

Cost & Risk

Better control over material cost, chemistry risk and process repeatability. ROI is driven by reduced alloy waste and lower process risk.

Production

Execution

Clear printed or on-screen charging and addition instructions at the furnace. Less ambiguity and fewer mistakes.

Metallurgy

Strategy

Transforms metallurgical expertise into repeatable calculation logic with controlled limits and source/product yield factors.

QC / Laboratory

Compliance

Links OES analysis directly to controlled correction decisions with traceability from sample to pour.

The ChargeCalc ecosystem

One workflow from planned charge to final pour.

ChargeCalc supports the operational chain that connects production planning, furnace charging, OES analysis, melt correction and documentation.

Initial charge design

ProdCalc

Transforms metallurgical know-how into an optimized, executable furnace recipe before melting begins.

  • Built-in product specifications and chemistry limits.
  • Optimized scrap and alloy mix against target chemistry.
  • Target charge mass, available source materials and source/product yield factors.
ProdCalc — Initial charge design
Melt correction

AdjCalc

Replaces repeated correction cycles and tribal knowledge with deterministic, analysis-linked correction decisions.

  • OES integration and instant out-of-spec flagging.
  • Predicted chemistry after recommended additions.
  • Precise, cost-optimized addition recommendations for operators.
AdjCalc — Melt correction
Workflow support

Schedule

Closes the loop between production planning, furnace execution and quality-control documentation.

  • Planned charges, products (alloy grades) and furnace allocation.
  • Links OES samples directly to the charge.
  • Tracks each charge from initial calculation to final pour.

The production risk

The practical risk of uncontrolled calculation methods.

After the workflow and modules are clear, the risk becomes easier to see: spreadsheets and generic AI do not provide the same controlled, repeatable and documented calculation environment.

ROI first

How quickly can ChargeCalc pay for itself?

The strongest business case is usually not the software itself. It is the effect on alloy usage, correction time, repeatability and process risk. ChargeCalc is positioned to help management evaluate payback using the foundry’s own products (alloy grades), source materials and OES workflow.

Lower alloy overuse

Reduce avoidable additions by calculating against exact chemistry targets instead of rule-of-thumb overcorrection.

Fewer correction loops

Use predicted chemistry after additions to reduce repeated correction cycles and shorten the path to final chemistry.

Less operator dependency

Replace fragile spreadsheet habits and tribal knowledge with a configured, repeatable calculation method.

Better process control

Reduce production risk through documented calculations, traceable analysis and a clearer decision chain.

Spectrometer compatibility

First confirm the data path, then calculate with confidence.

ChargeCalc can be configured around file-based OES export and import routines from widely used instrument manufacturers, linking measured chemistry directly to charge design, melt correction and documentation.

Evaluate with real data

Do you want to control the cost?

The best way to evaluate ChargeCalc is with your own products (alloy grades), source materials and OES workflow. Alutron can help estimate where ChargeCalc will reduce cost, correction time and process risk in your specific environment.
