Abstract

See full text

The invention provides a casting equipment (1) for casting melt (15) into a cast product (80) comprising a supply reservoir (10) for supplying the melt (15), a distribution reservoir (20), a casting apparatus (25) having a melt inlet connected to the distribution reservoir (20) for producing the cast product (80), a supply conduit (30) fluidly connecting the supply reservoir (10) and the distribution reservoir (20), an electromagnetic pump (35) provided on the supply conduit (30) and operable to generate a force in the melt (15) in the supply conduit (30), a level sensor (40) for measuring a level of the melt (15) in the distribution reservoir (20) and/or in the supply reservoir (10), a controller operably connected to the pump (35) and the level sensor (40), wherein the supply conduit (30) is sealed or sealable from a pressure of the atmosphere, wherein the controller is configured to control an operation of the pump (35) based on a level signal from the level sensor (40), and wherein, at least during a steady-state casting operation, the casting equipment is configured such that the supply conduit (30) defines a flow path that has a point that is higher than a surface of the melt in the supply reservoir (10) and/or the distribution reservoir (20), and the pump (35) is operated such that the metal level in the distribution reservoir (20) is at a predefined level such as to control a pressure of the melt (15) in the melt inlet of the casting apparatus (25).
