Statistical research using the multiple regression analysis in areas of the cast hipereutectoid steel rolls manufacturing

Multivariate Statistical Research in Areas of the Cast Hyper-Eutectoid Steel Roll Manufacturing, in the Melting and Alloying Processing Stages

“…Prediction of the exploitation properties of rolls, based on the melting and alloying process of the alloys, is a prerequisite for the cast roll's manufacturing [1][2][3][4][5][6][7][8]. The statistical modelling by multivariate regression analysis can be used successfully to optimize the chemical composition during the rolls manufacturing process.…”

“…The statistical modelling by multivariate regression analysis can be used successfully to optimize the chemical composition during the rolls manufacturing process. In this way, this method is very helpful to predict the cast roll's performance [1][2][3][4][5][6][7][8].…”

“…We reported several studies [1][2][3][4][5][6][7][8], on mathematical modelling of cast rolls. In all the above studies, the combined effect of basic chemical composition in addition to the proper alloying elements has been considered separate or simultaneously, in case of the cast iron rolls [1][2][3][4][5][6][7][8].…”

“…We reported several studies [1][2][3][4][5][6][7][8], on mathematical modelling of cast rolls. In all the above studies, the combined effect of basic chemical composition in addition to the proper alloying elements has been considered separate or simultaneously, in case of the cast iron rolls [1][2][3][4][5][6][7][8]. Most of the studies reviewed above worked on modelling of cast iron rolls and their technological components which assure the proper hardness by the chemical composition variation, but not reviewed the cast steel-base rolls [1][2][3][4][5][6]8].…”

“…Most of the studies reviewed above worked on modelling of cast iron rolls and their technological components which assure the proper hardness by the chemical composition variation, but not reviewed the cast steel-base rolls [1][2][3][4][5][6]8]. In the last 20 years, a general model for cast iron rolls is developed by the author, which can be applied now, in new research series, to the hyper-eutectoid steel rolls too [1,7]. The current analysis is based on the concept that is proven in several scientific works that the proper quality of a particular type of alloys (such as these hyper-eutectoid steels) and their properties are determined by chemical composition and a proper melting and alloying processing [1][2][3][4][5][6][7][8].…”
