Numerical and experimental analysis of chemical heterogeneity of solidifying heavy ductile cast iron roller

Popis výsledku v původním jazyce

The quality of the working rollers used for rolling rails is determined by the chemical and structural composition of the material of the rollers and the production technology. It is necessary to cast rollers with significantly improved utility properties, mainly high wear-resistance and optimal mechanical and structural properties. It is therefore necessary to find and ensure optimal relationships between the matrix structure and the resultant values of the mechanical properties of the rollers in orderto maximize the length of life. The requirements introduced here cannot be ensured without knowledge of the kinetics of the solidification. Therefore numerical and experimental investigation of temperature field of the solidifying roller was conducted.The kinetics of the solidification has a measurable and non negligible influence on the chemical and structural heterogeneity of the investigated type of ductile cast iron. Tying on to the results of the model of the temperature field of
