SQintegra - a powerful user-friendly software for advanced evaluation of quenchant data from ivf SmartQuench

SQintegra is an extension of the ivfSmartQuench software originally used for handling and evaluation of cooling curves

With the two new modules HTC and Property Prediction it is now possible to

-> Calculate Heat Transfer Coefficients from the measured cooling curves

-> Calculate hardness and microstructure distributions for cylindrical geometries

Step 1. Measurement of cooling curve

Step 2. Calculation of heat transfer coefficient – first iteration

• Inverse calculation
• Direct calculation
• The HTC determined is valid at the surface of the probe at the same height as the thermocouple

Step 3. Calculation of heat transfer coefficient – completed (addition of time steps)

Step 4. Heat Transfer Coefficient vs. Temperature or Time

Temperature difference: calculated – measured

Step 5. Property Prediction
Input Data

Input Steel data, TTT approach (Réti et al. 1981)

Step 6. Calculation of microstructure and hardness
