Problems solved by technology

However, if the acceleration of the pull-up is too high, there is a problem that the molten metal pulled up by the starter device will be broken before the desired pull-up speed is reached, and casting cannot be performed.
On the other hand, if the acceleration of the pull-up is reduced in order to prevent the breaking of the molten metal at the time of acceleration, it takes time to reach the desired pull-up speed, resulting in poor productivity.

Embodiment approach 1

[0027] First, refer to figure 1 The free casting device (uplift type continuous casting device) according to Embodiment 1 will be described. figure 1 It is a schematic cross-sectional view of the free casting device according to Embodiment 1. Such as figure 1 As shown, the free casting apparatus according to Embodiment 1 includes a molten metal holding furnace 101 , a shape defining member 102 , a support rod 104 , an actuator 105 , a cooling gas nozzle 106 , and a drawer 108 . figure 1 The xy plane in constitutes the horizontal plane, and the z-axis direction is the vertical direction. More specifically, the positive direction of the z-axis is vertically upward.

[0028] The molten metal holding furnace 101 accommodates molten metal M1 such as aluminum and its alloy, and maintains it at a predetermined temperature at which the molten metal M has fluidity. exist figure 1 In the example of , since the molten metal is not supplied to the molten metal holding furnace 101 dur...

Embodiment approach 2

[0056] Next, refer to Figure 6 , 7 The free casting device according to Embodiment 2 will be described. Figure 6 It is a plan view of the shape defining member 102 according to the second embodiment. Figure 7 It is a side view of the shape regulating member 102 according to the second embodiment. in, Figure 6 , 7 The xyz coordinates in are also the same as figure 1 unanimous.

[0057] because figure 2 Since the shape defining member 102 according to the first embodiment shown is composed of one plate, the thickness t1 and the width w1 of the molten metal passing portion 103 are fixed. In contrast, as Figure 6 As shown, the shape regulating member 102 according to Embodiment 2 includes four rectangular shape regulating plates 102a, 102b, 102c, and 102d. That is, the shape defining member 102 according to Embodiment 2 is divided into a plurality. With such a configuration, the thickness t1 and the width w1 of the molten metal passing portion 103 can be changed. ...

Abstract

In an upward-drawing continuous casting method according to one embodiment of the present invention, a starter (ST) is used to draw upward a molten metal (M1) held in a holding furnace (101). When accelerating the starter (ST) to a prescribed upward-drawing speed during casting initiation, the following intervals are provided: a first acceleration interval in which the starter is accelerated at a first acceleration from a stopped state to a first speed; a second acceleration interval in which the starter is accelerated at a second acceleration from the first speed to a second speed; and a constant speed interval which occurs between the first acceleration interval and the second acceleration interval, and in which the starter is drawn upward at the first speed.

Description

technical field [0001] The present invention relates to a pull-up continuous casting method. Background technique [0002] In Patent Document 1, a free casting method is proposed as an epoch-making upward-drawing continuous casting method that does not require a mold. As shown in Patent Document 1, if the starter (starter) is immersed in the surface (ie, molten metal surface) of molten metal (molten metal), and the starter is drawn up, due to the surface film and surface tension of the molten metal, , the molten metal is also guided out following the starter. Here, a casting having a desired cross-sectional shape can be continuously cast by drawing out the molten metal through a shape defining member provided near the molten metal surface and cooling it. [0003] In a normal continuous casting method, not only the cross-sectional shape but also the shape in the longitudinal direction is prescribed by the mold. In particular, in the continuous casting method, since the sol...
