Striae, glass, glass melting, regression, optimal parameters


This research is focused on the problems of setting of the optimal parameter of melted glass in real conditions. To achieve the best quality of glass products, the striae (inhomogeneity) value must be smallest or ideally minimal. In this paper, the value of striae is minimized from aspect of parameters of melting process p1, ..., pn by constructing a regression model in the form y = f (p1, ..., pn), where f is a polynomial of n variables. The description of the striae using a regression functions in glass industries is an original idea of the authors. This unique method has been developed in cooperation with developers in the development of a new innovative technology of production of glass. It is apparent, that the optimal setting of parameters of melting process p1, ..., pn has economic and practical importance (the parameters p1, ..., pn describe performance of electro – heating, the value of the actual off take of glass melt, the temperature of the front and rear zone of the gutter, the temperature at the bottom of the furnace etc.). Chemical striae have often negative effect on the glass properties, and elimination of striae has been a key problem in glass science and technology. On the basis of the experiments and obtained results, it able to propose and recommend a method for minimized of value of striae. Moreover, another important knowledge could be used for modernization and effective the process of industrial production of glass in practical application in military technologies.
