Abstract

A comparative analysis of metal pouring into rotating molds using the siphon method and top pouring was performed. A new top pouring method is proposed to reduce defects of shrinkage origin: looseness, central porosity, liquation, etc. The method is based on rotating the mold during pouring around its axis or moving a metal melt stream relatively to the rotating mold. The peculiarity of the process is that steel pouring is carried out along the inner wall of the mold. The results of experimental cold physical modeling are presented. A glycerol solution was used as a model liquid. The results of cold modeling showed that implementing the proposed pouring method results in temperature losses averaging up to 5%. Taking into account the scale factor, higher values can be expected in a real process.
