Embodiment approach 1

[0066] First, refer to figure 1 The free casting device (uplift type continuous casting device) of Embodiment 1 will be described. figure 1 It is a cross-sectional view showing a configuration example of the free casting apparatus according to the first embodiment. Such as figure 1 As shown, the free casting apparatus according to Embodiment 1 includes a molten metal holding furnace (holding furnace) 101 , an external shape defining member 102 a , a support rod 103 , an actuator 104 , a cooling nozzle 105 , and a lead-out unit 106 .

[0067] The molten metal holding furnace 101 accommodates molten metal M1 such as aluminum or its alloy, for example, and keeps it at a predetermined temperature. In this embodiment, the case where the molten metal M1 is aluminum is demonstrated as an example. In addition, of course, the molten metal M1 may be other metals or alloys than aluminum. In addition, in figure 1 In the example of , since the molten metal is not supplied to the molte...

Embodiment approach 2

[0088] Figure 7 It is a cross-sectional view showing a configuration example of a free casting device according to Embodiment 2. Figure 7 Free casting setup shown with figure 1 The shape of the starter ST is different compared to the free casting device shown. Figure 7 Other configurations of the free casting device shown are the same as figure 1 The same is true for the free casting device shown, and therefore its description is omitted.

[0089] Figure 8 It is a perspective view showing a configuration example of a starter ST according to the second embodiment. Figure 8 The illustrated starter ST is composed of a main body (prismatic main body in this example) 107 and a convex portion (first convex portion) 110 . In addition, the main body portion 107 is integrally formed with the convex portion 110 . Here, the convex portion 110 protrudes from the side surface of the main body portion 107 . As a result, molten metal M1 is held up by the convex portion 110 when t...

Abstract

The present invention provides a hoisting-type continuous casting device and a hoisting-type continuous casting method. The hoisting-type continuous casting device is provided with the following: a molten metal holding furnace (101) for holding a molten metal (M1), a starter (ST) for leading the molten metal (M1) out from a surface of the molten metal (M1) held in the molten metal holding furnace (101); and a shape regulation member (102) for regulating the cross-sectional shape of a casting (M3) being cast by applying an external force to held molten metal (M2) that was led out by the starter (ST). The starter (ST) is provided with a trunk (107), and a leading end section (108) having a leading end (109) that has a smaller cross-sectional area in the horizontal direction than the trunk (107).

Description

technical field [0001] The invention relates to an upward-drawing continuous casting device and an upward-drawing continuous casting method. Background technique [0002] In Patent Document 1, the inventors propose a free casting method as an epoch-making upward-drawing continuous casting method that does not require a casting mold. As shown in Patent Document 1, after a starter (starter) is dipped in the surface of molten metal (molten metal) (that is, the molten metal surface), if the starter is drawn up, the molten metal passes through the surface film of the molten metal, Surface tension is also derived following the starter. Here, a casting having a desired cross-sectional shape can be continuously cast by drawing out molten metal through a shape defining member provided near the molten metal surface and cooling it. [0003] In a typical continuous casting method, the cross-sectional shape is prescribed by a mold and the shape in the longitudinal direction is also pre...
