Embodiment 1

[0038] This embodiment provides a continuous casting device, such as figure 1 shown, including:

[0039] The molten pool 1 is used to store molten metal 8 and has through holes 2 for continuous casting;

[0040] The lead rod 5 can sealably extend into the continuous casting through hole 2, and is used to guide the metal that has solidified in the continuous casting through hole 2 from the continuous casting through hole 2 to the molten pool 1 when the continuous casting starts. external operation;

[0041] The cooling device 4 is used for cooling the lead rod 5 or the solidified metal, and through the heat transfer effect of the lead rod or the solidified metal, the molten metal located in the continuous casting through hole 2 flows in the lead rod 5 Or further cooling and solidification on already solidified metal;

[0042] The pulling device 7 is used to pull the draw bar 5 or the solidified metal away from the molten pool 1 .

[0043]In the continuous casting device of ...

Embodiment 2

[0071] The present embodiment provides a continuous casting method, comprising the following steps:

[0072] S1: plugging the continuous casting through hole 2 located on the side wall of the molten pool 1 with a refractory material;

[0073] S2: Inject molten metal into the molten pool 1 to make the molten metal higher than the continuous casting through hole 2;

[0074] S3: Place the guide rod 5 on the traction device 7, and use the guide rod 5 to open the refractory material in the continuous casting through hole 2 after aligning with the continuous casting through hole 2, so that the guide rod 5 enters the continuous casting through hole 2;

[0075] S4: Open the cooling device 4 to cool the lead rod 5, so that the molten metal positioned in the continuous casting through hole 2 is cooled and solidified at the front end of the lead rod 5 (only at the beginning of continuous casting, the molten metal is cooled at the front end of the lead rod 5 solidification, and then the ...

Embodiment 3

[0084] This embodiment specifically provides a continuous casting method for aluminum alloy liquid, comprising the following steps:

[0085] S1: plugging the continuous casting through hole 2 located on the side wall of the molten pool 1 with a refractory material;

[0086] S2: Inject aluminum alloy liquid into the molten pool 1 so that the aluminum alloy liquid is 10mm higher than the horizontal centerline of the continuous casting through hole 2, and in the subsequent steps, the aluminum alloy liquid in the molten pool 1 should maintain this distance so that The temperature of the aluminum alloy liquid in molten pool 1 is maintained at 670°C;

[0087] S3: Place the guide rod 5 on the traction device 7, and use the guide rod 5 to open the refractory material in the continuous casting through hole 2 after aligning with the continuous casting through hole 2, so that the guide rod 5 enters the continuous casting through hole 2;

[0088] S4: Open the cooling device 4 to cool the...

Abstract

The invention provides a continuous casting device comprising a molten pool, a guide rod, a cooling device and a traction device. According to the continuous casting device, molten metal is solidified in a continuous casting through hole under the heat conduction effect of the guide rod or metal solidified previously, large cooling devices such as crystallizers do not need to be arranged, and therefore the space occupied by the whole continuous casting device can be reduced; and for the same reason that no large devices such as the crystallizers are used, multiple continuous casting blanks can be arranged side by side, the multiple continuous casting blanks are arranged as closely as possible, more continuous casting lines can be arranged within the same space, and the continuous casting efficiency is improved. In addition, as long as the cooling effects of the cooling devices are the same, the traction device can pull the guide rod and the casting blanks at a constant speed, and therefore the surfaces of the casting blanks can be smooth and clean, surface defects are greatly reduced, and pressure of subsequent surface processing steps is reduced.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a continuous casting device. Background technique [0002] Ingot casting is a forming method of casting molten metal into an ingot whose shape, size, composition and quality meet the requirements. In recent years, metal ingot casting technology has been continuously improved, and new methods and new processes have emerged, especially continuous ingot casting technology has been continuously improved and developed. Continuous ingot casting is a high-efficiency method different from ordinary fixed-die ingot casting method. It is characterized in that while the metal is solidified, the ingot is constantly moving towards the casting direction. In theory, it can prepare billets of unlimited length and realize continuous production. The vast majority of metal ingots are obtained by continuous ingot casting technology. [0003] In order to ensure the matching of casting speed and cool...
