    摘要： A feed system is provided for conveying molten metal to a thin section caster having mold surfaces moving exclusively in the direction of casting. The feed system has a passage of circular cross section adjacent to one end thereof for receiving molten metal and a rectangular cross section at the delivery end thereof adjacent to the caster. The feed system is designed for supplying molten metal to the caster at low pressure for "closed-pool" type caster operation. The point of highest elevation in the metal flow passage of the feed system is on the upper surface of a transition portion where the cross section changes from circular to rectangular adjacent to the nozzle. The level or height of the high point above the centerline of the nozzle exit is selected so as to be less than the pressure of the metal measured in inches at the nozzle exit. This feature enables the maintenance of positive pressure in the metal within the feed system so that ingress of air into the metal is prevented.

    摘要翻译： 提供一种供料系统，用于将熔融金属输送到具有仅在铸造方向上移动的模具表面的薄壁铸造机。 进料系统具有邻近其一端的圆形横截面的通道，用于接收熔融金属，并且在其与输送机相邻的输送端处具有矩形横截面。 进料系统设计用于在“闭池式”连铸机操作的低压下向浇铸机供应熔融金属。 进料系统的金属流动通道中的最高高程点位于横截面从喷嘴附近的圆形到矩形的过渡部分的上表面上。 选择喷嘴出口中心线以上的高点的高度或高度，以便小于在喷嘴出口处以英寸测量的金属的压力。 该特征使得能够在进料系统内的金属中保持正压，从而防止空气进入金属。
