Embodiment 1
[0046] Please refer to figure 1 , The variable gap ladle system 100 of the embodiment of the present invention includes: a melting furnace 10, a holding furnace 20, a ladle 30, a quench roll 40, a temperature control device and a liquid level control device. The melting furnace 10, the holding furnace 20 and the ladle 30 are connected in sequence. The bottom of the ladle 30 is provided with a variable slit gate 303 , and the quenching roll 40 is arranged below the variable slit gate 303 . In this embodiment, the quenching roll 40 is a single roll. The temperature control device and the liquid level control device are arranged on the ladle 30 to control the temperature and liquid level of the alloy liquid in the ladle 30 .
[0047] Please refer to figure 1 The smelting furnace 10 includes a first smelting furnace 101 and a second smelting furnace 102 which are independent of each other, and the melt outlets of the first smelting furnace 101 and the second smelting furnace 10...
Embodiment 2
[0053] Please refer to Figure 6 , the variable gap ladle system 100 of this embodiment of the present invention is basically the same as that of Embodiment 1, the difference is that the quenching roll 40 of this embodiment is a double roll, and other identical parts are not repeated in this embodiment. Alloy sheets were prepared by twin rolls.
[0054] Such as Figure 6 As shown, two parallel double rollers 40 are located below the variable gap gate 303 . The two roller bodies are arranged at intervals, and the interval distance corresponds to the width of the plate. Therefore, the thickness of the sheet can be adjusted by adjusting the distance between the two rollers. The gap between the two rollers corresponds to the variable gap gate 303 . exist Figure 6 From the viewing angle shown, the left roller rotates clockwise and the right roller rotates counterclockwise. The alloy liquid flowing between the two rollers is rapidly condensed into an alloy sheet.

Embodiment 3
[0057] The preparation method of the light metal alloy strip in the embodiment of the present invention is prepared by using the slot-type light metal alloy strip throwing device of the present embodiment, which includes the following steps:
[0058] (1) The light metal alloy is smelted in the smelting furnace 10 into an alloy liquid and then transported to the holding furnace 20 for heat preservation, so that the composition of the alloy liquid is uniform and the temperature is stable.
[0059] (2) Open the automatic control valve 604, the alloy liquid in the holding furnace 20 is transported in the ladle 30, until the alloy liquid injected reaches the detection height of the liquid level sensor 603, then close the automatic control valve 604; meanwhile, according to the temperature The temperature parameter detected by the sensor 601 is used to control the heating temperature of the heating element through the temperature controller 602, so that the alloy liquid is kept at th...
