Title
Growth Stability of Plate and Tube Shaped Sn Crystals in the Upward Continuous Casting Process
진현진Hyun Jin Shin, 김지준Ji Joon Kim, 홍준표Chun Pyo Hong
Abstract
The Upward Continuous Casting process which manufactures near-net shaped crystals directly from the melt has been improved in order to reduce the cost of products. Growth of plate and tube shaped crystals using the U.C.C. process was carried out with tin. Near-net shaped tin plates and tubes have been produced with the newly developed mold. The effects of process parameters on the size and the shape of the crystal were studied:these were the meniscus height(S), the length between the top surface of the mold and free surface(H), the mold temperature, and the pulling speed. Of these S and H were the most important parameters in determining the crystal shape stability. The U.C.C. process was compared with other shaped growth methods to determine its growth stability. It can be concluded that the U.C.C. process will find applications in the growth of various shaped crystals.
