Abstract
Official abstract text for this publication.
A method for manufacturing a pipe with a rib, in which a rib portion formed inside a pipe portion includes bent portions in accordance with bending of the pipe portion or a twisted portion in accordance with twisting of the pipe portion, includes drawing out molten metal held in a furnace by using a starter, from a surface of the molten metal, and drawing up the molten metal through a shape defining member defining a sectional shape of the pipe with the rib to be cast, and cooling and solidifying the molten metal passed through the shape defining member and drawn up. The bent portions are formed by moving at least one of the starter and the shape defining member in a horizontal direction. The twisted portion is formed by rotating at least one of the starter and the shape defining member about an axis extending along a vertical direction.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing a pipe with a rib, in which a rib portion formed inside a pipe portion includes a plurality of bent portions in accordance with bending of the pipe portion, comprising: drawing out molten metal held in a molten metal holding furnace by using a starter, from a surface of the molten metal, and drawing up the molten metal through a shape defining member that defines a sectional shape of the pipe with the rib to be cast; and cooling and solidifying the molten metal that has passed through the shape defining member and been drawn up, wherein the plurality of bent portions are formed by moving at least either one of the starter and the shape defining member in a horizontal direction. 2 . The method for manufacturing a pipe with a rib according to claim 1 , wherein cooling gas is introduced to an inner side of the pipe with the rib to be cast, and an opening is provided in the starter. 3 . A method for manufacturing a pipe with a rib, in which a rib portion formed inside a pipe portion includes a twisted portion in accordance with twisting of the pipe portion, comprising: drawing out molten metal held in a molten metal holding furnace by using a starter, from a surface of the molten metal, and drawing up the molten metal through a shape defining member that defines a sectional shape of the pipe with the rib to be cast; and cooling and solidifying the molten metal that has passed through the shape defining member and been drawn up, wherein the twisted portion is formed by rotating at least either one of the starter and the shape defining member about an axis that extends along a vertical direction. 4 . The method for manufacturing a pipe with a rib according to claim 3 , wherein cooling gas is introduced to an inner side of the pipe with the rib to be cast, and an opening is provided in the starter.
