How Do I Track Furnace Performance?

Furnace performance is tracked by connecting heat numbers, charge mix, melting time, furnace status, downtime, energy use, output, quality test results, rejection, and casting traceability in one system. For a foundry, the furnace is not just another machine. It is one of the main cost, quality, and capacity drivers.

If furnace performance is reviewed only at the end of the month, the foundry loses the chance to correct problems while they are happening. ERP and IoT visibility can help teams understand each heat, each stoppage, each quality result, and each cost impact more clearly.

AICAN Optiwise helps manufacturers connect production, inventory, quality, maintenance, finance, dispatch, and reporting so furnace performance can be reviewed with operational context.

Start with heat number discipline

Heat number tracking is the foundation of furnace performance control. Every heat should connect to material consumed, furnace used, output produced, quality result, and casting batches affected.

ERP should capture:

• Heat number
• Furnace name or ID
• Date and shift
• Grade or alloy
• Charge mix reference
• Operator or shift reference where used
• Quantity melted
• Quantity poured
• Linked production orders

This creates traceability and helps quality teams investigate issues later.

Track charge mix and material consumption

Furnace performance is affected by raw material quality, scrap, alloys, returns, and charge planning.

Track:

• Raw material issued
• Scrap or return material used
• Alloy additions
• Consumption quantity
• Material cost
• Balance stock
• Variance from planned charge

This helps the foundry understand whether cost and quality issues begin from the material side.

Monitor melting time and downtime

A furnace may lose performance because of long melting cycles, power issues, breakdowns, waiting for charge material, waiting for moulds, or maintenance delays.

Useful tracking includes:

• Heat start time
• Heat end time
• Melting duration
• Waiting time
• Downtime reason
• Breakdown details
• Maintenance action
• Output loss

This helps management identify whether the issue is equipment, material planning, maintenance, or production coordination.

Connect furnace data with quality

Furnace performance must be reviewed alongside quality results. A fast melt that creates quality problems is not a successful heat.

ERP should connect:

• Heat number
• Test result
• Chemical or quality reference where applicable
• Casting batch
• Defect type
• Rejection quantity
• Rework or repair
• Customer complaint where configured

This gives a clearer picture of process performance.

Review energy and cost impact

Energy is a major cost in furnace operations. Even when exact automatic energy integration is not available, foundries can still track useful cost data through structured records.

Review:

• Energy or fuel reference where configured
• Furnace utilization
• Melting time
• Rejection cost
• Rework cost
• Material cost per heat
• Output per heat

This helps owners identify expensive patterns and improve planning.

Where Optiwise fits

Optiwise can help foundries connect furnace performance with ERP workflows such as heat tracking, charge mix, inventory, production, quality, maintenance, costing, and dispatch.

A practical implementation can focus on:

• Heat number traceability
• Charge mix tracking
• Furnace status and downtime
• Quality result linkage
• Rejection analysis
• Maintenance records
• Cost dashboards

AICAN helps foundries build visibility around the processes that affect quality and margin most.

Founder’s Note

A furnace record should tell more than what was melted. It should show what was planned, what was consumed, how long it took, what quality result came out, and what it cost the business. At AICAN, we believe that kind of operational clarity is the base for better foundry decisions. Learn more at About AICAN.

FAQs

How do I track furnace performance?

Track heat numbers, charge mix, furnace status, melting time, downtime, energy or fuel references, quality results, rejection, and cost impact.

Why are heat numbers important?

Heat numbers connect furnace operation with material consumption, casting output, quality results, rejection, and traceability.

Can ERP track furnace downtime?

Yes. ERP can capture downtime reason, duration, affected heat or job, maintenance action, and output loss.

How does furnace tracking improve quality?

It connects heat data with test results, defects, rejection, and rework so teams can identify process patterns.

What furnace reports should foundries review?

Useful reports include heat traceability, charge mix variance, melting time, downtime, rejection by heat, maintenance issues, and cost per heat.
