An analysis of thermal properties of steel during the quenching

Since, during the quenching of workpieces, transient temperature field in them depends on specific heat capacity, c, heat conductivity coefficient, λ, density, ρ, heat transfer coefficient α, these variables were evaluated in creation of quenching model of workpieces. Estimation of dependency on temperature of specific heat capacity, heat conductivity and heat transfer coefficients, which are involved in mathematical model of quenching of steel workpieces, was done using a calibration, based on Crafts-Lamont diagrams.
