The present disclosure relates to a hot rolling apparatus for manufacturing a metal plate by hot-rolling-treating a metal material including copper. The apparatus includes: a rough rolling device for rolling-treating the metal material, which has been heating-treated, a plurality of times with a back-and-forth movement of the metal material, to mold the metal material into a metal plate; a heat retention/application treatment device for retaining heat of or applying heat to the metal plate molded by the rough rolling device at lower temperatures than in the heating treatment, without applying bending; a finish rolling device for further rolling-treating the metal plate that has been heat-treated by the heat retention/application treatment device; a cooling device for cooling the metal plate that has been rolling-treated by the finish rolling device; and a support table for movably supporting the metal plate from below before and after the rough rolling device while the metal material is moved back and forth by the rough rolling device. According to the present disclosure, it is possible to improve the quality of the metal plate manufactured in the hot rolling apparatus, and also to improve the speed of the process required for rolling.

Hot rolling apparatus

A method of pulling a crystal of a metal oxide is disclosed, in which the growth of the crystal is performed in a liquid phase having a composition which is different from the metal oxide and which contains components constituting the metal oxide. The liquid phase is in contact with a solid phase located at a position separated from the position at which the crystal of the metal oxide grows. The solid phase has a composition different from that of the metal oxide and supplies components constituting the metal oxide to the liquid phase.
