Digital heat treatmentStart with the real workpiece.
Connect quenchants, fixtures, internal temperature measurement and process data to evaluate cooling against the required microstructure and properties.

Why digital heat treatment
How a medium cools
is not how a workpiece cools.
Standard-probe tests describe the medium under specified conditions. Workpiece material, section, surface condition and relative motion all affect actual cooling. Burn-off and film formation by organic polymer quenchants on hot workpieces also change heat transfer.
ANRAN starts with internal temperature measurements in real workpieces, checking cooling intervals against as-quenched hardness, microstructure and properties to match the quenchant and fixtures.

Technical discussion
Start with your question.
No lengthy process questionnaire is needed.
Start with the material, workpiece or current issue.
How do I select a quenchant?
Start with the material, effective section and target properties, then consider bath temperature, concentration, relative motion and equipment. Maximum cooling rate alone is not a complete selection criterion.
Does a standard-probe curve represent a real workpiece?
Not directly. Standard probes compare medium characteristics; internal workpiece curves describe actual cooling. As-quenched hardness, microstructure and dimensions still require workpiece inspection.
When are custom quenching fixtures needed?
Large, thin, long-shaft, ring-shaped or complex workpieces, and parts sensitive to uneven support or flow, require fixture discussions covering location, support, lifting, transfer and cooling passages.
Can I enquire without complete test data?
Yes. Leave a reply email and briefly describe your material, product need or issue. Drawings, curves and reports can be provided later if needed; no initial upload is required.
