Abstract

A pulling-up-type continuous casting apparatus according to an aspect of the present invention includes a molten-metal holding furnace (101) that holds molten metal (M1), a shape defining member (102) disposed in a vicinity of a molten-metal surface in the molten-metal holding furnace (101), the shape defining member being configured to define a cross-sectional shape of a cast-metal article (M3) to be cast as the held molten metal (M2) passes through the shape defining member (102), and an actuator (104) that applies a pressure to the molten metal (M1) held in the molten-metal holding furnace (101) and thereby makes the held molten metal (M2) pass through the shape defining member (102).

Description

technical field [0001] The invention relates to an upward-drawing continuous casting equipment and an upward-drawing continuous casting method. Background technique [0002] The inventors of the present application have proposed in Patent Document 1 a free casting method as a revolutionary continuous casting method that does not require any molds. As shown in Patent Document 1, after the starter is dipped below the surface of the molten metal (molten metal), that is, the surface of the molten metal, the starter is pulled up so that some of the molten metal in the molten metal is The surface film and / or surface tension of the molten metal follows and is pulled upwards through the starter. It should be noted that it is possible to continuously cast a cast metal product having a desired cross-sectional shape by drawing molten metal by means of a shape-defining member disposed near the surface of the molten metal and cooling the drawn molten metal. [0003] In ordinary continu...
