Commercial scope
Water-based polymer quenchants, quenching oils, custom quench fixtures, cooling-characteristic testing and internal workpiece temperature measurement.
About Anran DHT
Digital heat treatment grounded in the real workpiece and production evidence
Anran DHT is the digital heat-treatment business of Luoyang Anran S&T Co., Ltd. We start from internal temperature curves in the real workpiece and link quenchants, fixtures and measurement equipment to post-quench hardness, microstructure and properties.
Scope · Method · Evidence
Engineering method
Define the material and workpiece boundary, match the medium and fixture, measure the actual process and lock a traceable operating window.
Evidence policy
Published values are tied to the stated sample, method and condition. Unreferenced crack-rate, life and cost claims are not treated as universal guarantees.
Core Method
A standard probe shows the medium response; the real workpiece shows how the part cools
A standard-probe result is not the surface or core result of a production workpiece. Water-based organic polymer quenchants thermally decompose and burn off on a hot workpiece, forming a protective surface film that changes interfacial heat transfer. Actual cooling also depends on material, effective section, geometry, surface, bath temperature, kinematic viscosity, relative motion, loading and transfer.
Medium baseline
Standard-probe measured curves compare media and document the response of the stated probe and test conditions.
Real process
Multi-point internal temperature curves record the actual cooling intervals and are not replaced by a probe curve.
Result assessment
Internal curves are checked against post-quench hardness, microstructure and properties. The system boundary ends at the quench result; tempering is set separately by the user.
Project Workflow
How a project is handled
Collect inputs
Material, drawing, section, mass, target properties, current process and tank.
Define the boundary
Transformation, hardenability, distortion, cracking and installed-equipment constraints.
Select and test
Medium, fixture, probe curve, internal temperature or first-article plan as required.
Close the loop
Link parameters, batch records and inspection results before production release.
Start with the workpiece and the current process
Send the material grade, dimensions/mass, target properties and current problem. We respond across quenchant, fixture, measurement and process layers.
