| 摘要 |
The invention provides a stirring apparatus which is used for stirring a melting material which is contained in a container. The stirring apparatus comprises a rotation shaft which is vertically arranged above a container and multiple blades which extend in a radial direction of the rotation shaft. Each blade on a front surface which contacts a melting material has an uneven structure which extends in at least one direction of either the vertical direction or the horizontal direction so as to enlarge a contact size with the melting material (such as liquid iron), thereby increasing stirring efficiency. |
