MEPROTEC Batchsmart

Process Intelligence for Bell Annealing

Every coil.
Perfectly positioned.

Batchsmart optimizes multi-furnace planning, coil compatibility, stack position and the individual annealing strategy—so quality targets are reached without unnecessary time or energy.

The Batchsmart principle

Analyze. Combine.
Position. Optimize.

From material history to the exact location of every coil inside every annealing charge.

01AnalyzeUse chemistry, reduction degree, pre-processes and product requirements.
02CombineCreate compatible charges across orders and available bell furnaces.
03PositionDetermine which coil belongs at the top, middle or bottom of the stack.
04OptimizeMeet quality targets with minimum annealing time and energy demand.

The planning challenge

When inherited rules
replace process knowledge.

Bell-annealing charges are often assembled with old spreadsheets and static product groups. The rules may still be used—but their origin, assumptions and technical validity are no longer transparent.

The schedule exists. The engineering rationale is missing.

Engineering-based planning

Multi-furnace optimization

The best charge
for the best furnace.

Batchsmart considers order demand, material compatibility, furnace availability, expected duration and energy demand simultaneously. Planning becomes a transparent optimization across the complete furnace fleet.

Position-specific optimization

Top is not bottom.
Every position matters.

Each coil experiences a different thermal environment depending on its location in the stack. Batchsmart determines the optimal coil order so every position reaches the required properties without extending the entire cycle unnecessarily.

Beyond the general recipe

One charge.
Three individual histories.

Batchsmart does not assume that one generic recipe describes every coil. It predicts the behavior of each position, adapts the process strategy and ends the cycle when all required parameters are reached—not later.

Predictive quality safeguards

Optimize productivity.
Respect every risk.

The shortest cycle is only valuable when product-specific failure modes and uniformity requirements remain under control.

Operational impact

Better charges.
Less time and energy.

Engineering-based charge and position planning turns hidden process reserves into measurable operational value.

Annealing timeRequired onlyThe cycle is not extended by avoidable safety margins.
Energy demandReducedNo unnecessary heating or soaking beyond target achievement.
Quality confidencePosition-basedEvery coil is assessed at its actual stack location.

Actual improvements depend on product mix, furnace fleet, existing planning rules, data availability and implementation scope.
