Foundry Heat and Pour Log Template
A heat and pour log is the foundry's core traceability record. It links a heat of metal to its chemistry, temperatures, treatment and the molds it filled, so a defect or customer query can be traced to its source.

Approvals
Starting point only. Adapt fields to your customer requirements and quality system, and keep heat numbers consistent with casting traceability records.
Digitize heat records into your ERP
Optional: a short review of how heat numbers and chemistry could be linked to lots and shipments.
Optional. The tool and every export work without this. No spam.
How to use the template
Fill in the heat number, alloy, furnace and temperatures, then describe the treatment and the patterns poured. Use the tables for chemistry and mechanical checks and sign off at the end. Export to PDF for the traveler or Word for a customized version, and file it with the casting lot.
- Use the same heat number on the lab report and casting tags.
- Record the temperature measurement method and its calibration.
- Note any delays that may affect fade of treatment.
What a good heat record contains
Traceability needs the heat number, alloy specification, tap and pour temperature, treatment, chemistry results, and the molds or patterns poured. For ductile iron, include the time between treatment and pour because magnesium fades. Many customers also require retained test bars or coupons and the results of tensile, hardness and microstructure checks per the applicable ASTM or customer standard.
Common mistakes
The most common issue is a record that cannot be matched to the castings. Keep the heat number on the mold, casting and shipping paperwork. Another is recording targets instead of actual readings, which hides drift in pour temperature.
- Logging planned temperatures instead of measured ones.
- Missing a chemistry sample after a late alloy addition.
- No record of the thermocouple or spectrometer calibration date.
- Heat numbers reused across shifts.
Frequently Asked Questions
Why record both tap and pour temperature?
The difference shows heat loss in transfer and ladle handling, which affects fluidity and defects such as misruns. Tracking both over time also shows whether ladle preheat and pour delay are under control.
How long should I keep heat records?
Follow your customer contract, quality system and any regulatory requirement. Aerospace and pressure-containing castings often require many years or the product life, and general industry commonly keeps records for several years. Confirm retention in your procedure.
Can I add fields for my customer?
Yes. Export to Word and add the customer's required fields such as specification revision, pour sequence or test bar identification. Keep the core heat number, alloy and results fields consistent.
Does this replace a MES or ERP record?
No. It is a paper or PDF-based record that works with or without a system. If you have an ERP or MES, use the same heat number in both so the paper log and the electronic lot can be matched.
If your foundry wants heat records captured on a tablet and linked to lots in the ERP, we can talk through options. The template is usable immediately without us.
