Assess quenching results from actual workpiece cooling
Anran’s digital heat treatment method connects the application of quenchants, measurement and fixtures. Define the workpiece and target, simulate its heat treatment using the patent-based product, obtain its dedicated cooling profile, then design fixtures and equipment from those results.
Prerequisites for intelligent system design
This section explains the technical method for intelligent systems and related dedicated fixtures, not a mandatory purchase sequence. Quenchants, testers, temperature measurement systems and fixtures can each be discussed and purchased independently.
The workpiece-specific cooling profile is a basis for fixture design, not a display added afterwards. Without that profile, neither a standard-probe test nor a website calculation fulfils this design prerequisite.
Why a probe curve is not a production workpiece curve
A standard probe has specified material, dimensions, surface condition and test conditions. Production workpieces differ in thickness, geometry, surface and loading.
A liquid-sample cooling curve cannot directly represent the surface and core of every workpiece. Anran’s technical team provides workpiece-specific application guidance.
Three data types, three different questions
| Data type | Question answered |
|---|---|
| Standard-probe measurements | How the medium cools under specified conditions |
| Software predictions | What the model predicts for the stated inputs and assumptions |
| Internal workpiece measurements | How a measured point inside this workpiece cools in the actual process |
Without workpiece measurements, a predicted curve must not be labelled measured. Without an applicable model, a probe curve cannot automatically yield a definitive core hardness.
Connecting cooling history with as-quenched properties
Interpretation of a temperature curve also depends on composition, pre-quench condition and measurement location. Anran relates internal temperature changes to subsequent hardness and microstructure checks to assess cooling intervals, select quenchants and adjust operations.
High-chromium cast iron calls for heavy-section hardening, surface-to-core consistency and fracture resistance. Cr–Mo steel SAG liners also require a balance of hardness, toughness and service requirements. Curves are important evidence but do not establish all properties independently of material and inspection results.

How this helps product selection
For quenchant selection, compare more than one cooling-rate value. For a tester, decide whether you need medium or workpiece measurements. For fixtures, establish the required cooling operation. Products and measurements can be coordinated around the same workpiece.
