Sažetak
Purpose: Developing of new methods for input data of mathematical model is established. Design/methodology/approach: Temperature dependency of both, heat transfer for quenchant with Grossmann severity of quenching H=0.35, which are adequate for oil and heat conductivity coefficients has been calibrated on the base of Crafts-Lamont diagrams. Findings: Evaluation of physical properties such as specific heat capacity, c, heat conductivity coefficient, λ, density, ρ, heat transfer coefficient, α involved in mathematical model of transient temperature field was done by the inversion method, or by calibrations. Research limitations/implications: In the future this investigation should be broaden on investigation of more quechants. Practical implications: By proper input data of mathematical model of steel quenching, correct computer simulation can be performed. Originality/value: New inverse method of input data such as specific heat capacity, c, heat conductivity coefficient, λ, density, ρ, heat transfer coefficient, α which is based just on achieved distributions of mechanical properties in Crafts- Lamont diagrams.
