Purpose: Model for prediction of mechanical properties of rolled steel products after final cooling from exit rolling temperature is one of the basis component of any software for complex computer simulation of rolling technologies. Theoretical background and implementation of such software tool is described. Design/methodology/approach: After calculation of cooling curves by any technology dependent Shell the software tool MECHP can be called to predict CCT Diagram from current chemical composition of steel and initial properties of deformes austenite first than structure shares (percentage of ferrite, pearlite, bainite and martensite) resulting from austenite decomposition process for given cooling curve and finally mechanical properties of final product after cooling (hardness, yield stress, tensile strength) are calculated. Implementation of MECHP tool into the software RollFEM3D Finite Elements Method simulation of rolling processes is presented. Findings: comparison of MECHP calculations with measured process data (water cooling and subsequent air cooling of hot rolled narrow plate and wire) shows correspondence that is satisfactory for using in control of process cooling technology. Practical imlications: Results of verification showed that the software tool MECHP is implementable as a postprocessor into off-line rolling process simulation software or can be used as a mechanical properties predictor in software for on-line control of cooling. Originality/value: Developing of technology independent Library solving the problem of final mechanical properties prediction for various kinds of rolling technologies.
