Reference QuenchProbe

Equipment for in-situDetermination of Cooling Characteristics ofQuenchants by Cooling Curve Analysis

Reference QuenchProbeis a result of research conducted at IIT Madras in the past 12 years. Six

research theses; four research projects; ten International Refereed Journal papers; eighteen International

and National Conference / Symposium / Workshop papers have been published so far, related to the

technology of Reference QuenchProbe.

Cylindrical alloy steelprobe (Same grade as component): For EXACTcooling rates with specific steel

grade and quenchant combination Unique probe design: Single temperaturemeasured near the surface

Advanced heat transfer software: Calculation of cooling rates at surface and core of specimenfrom

measurement at one point

Steel Heat Treatment Analysis (TmmFE)

Steel Heat Treatment Analysis (TmmFE) is Finite element software for simulating heat treatment process

and its metallurgical implications at virtual sensor locations considering steel properties and TTT diagram.

The mathematical model will be built based upon the customer specific steel and quenchant combination

to calculate temperature contours and metallurgical implications at different points of the componenthence giving the accurate results.

The TTT diagram and material properties of customer specific steel will be taken into account for the

analysis thereby increasing the accuracy of the output results.

Applications:

Steel Casting Heat Treatment

Steel Forging Heat Treatment

Heat Treatment of machined components

Benefits:

Cooling Rate Curves at different locations

Compute Microstructure variation at different locations

Estimate the Hardness at different locations

Simulation of Temperature contour for complete heat

treatment process from heating to quenching Transferring time data is also considered for calculations

Simulate actual component virtually before conducting

the manufacturing process, thereby saving cost of

destructive testing

ASTM QuenchProbe

Equipment for Standard Tests for the Determination of Cooling

Characteristics of Quenchants by Cooling Curve Analysis as per ASTM

D6200-01(For Quench Oils) and as per ASTM D6482-06(For Aqueous

Polymer Quenchants with Agitation)

Applications: Measurement of quenching capacity of different quenching

mediums (oils, polymer solutions etc) as per ASTM D6200-01 for

ease of comparison of data worldwide

Selection of proper quenchant based on comparison of different

quenchants

Check the health of quenchants with continued use

Check the effect of agitation on cooling rates

Check the effect of contamination in quenchants (water in oil;

polymer in oil etc.)

Inspection of quenchants in as-received condition

InverseSOLVER

InverseSOLVER is based on a serial algorithm for the

Inverse Heat Conduction Problem (IHCP) developed

to estimate the individual flux components at the

unknown boundary. In many practical problems the

surface conditions are not known a-prior. In such

cases the surface conditions will have to be

estimated under simulated or laboratory

conditions.

Applications:

Estimation of heat flux on the heat shields during re-entry of space vehicles for the Indian Space Research

Estimation of space and time varying multiple heat flux components at the metal-mold interface during net

shape casting of continuous casting of steel, for a consortium of steel companies

Estimation of space and time varying multiple heat flux components (six components along the mold wall) at

the metal-mold interface during continuous casting of thin steel slabs and filling in aluminum die casting

Estimation of metal-mold interface heat flux during die casting of cast iron moulds for a leading foundry

Estimation of heat flux due to the welding arc during TIG welding

Estimation of heat flux during quenching of steel specimens

Estimation of heat flux at the metal-mold interface corners of solidifying aluminum bars and slabs

Estimation of heat flux on the plasma facing components in the Tokomak.
