Problems solved by technology

[0002] There are many difficulties in the establishment of castable metal material database and process parameter database of twin-roll casting technology
The casting speed of a typical experimental caster is generally only a few meters per minute. It is difficult to achieve stable momentum, heat and mass distribution in the molten pool. The quality of molten metal in an experiment is difficult to support the emergence and continuation of the dynamic stable stage of casting and rolling.
For typical industrial casters in iron and steel enterprises, it is costly and time-consuming to explore the material composition and corresponding process parameters suitable for twin-roll casting and rolling technology.

Embodiment 1

[0038] Embodiment 1 of the present invention discloses a device for simulating the key transmission mechanism of the twin-roll casting and rolling pool, such as figure 1 , figure 2 , image 3 shown. The first cooling base 7 is located above the first container wall 9 , and the second cooling base 8 is located above the second container wall 10 . The first cooling matrix 7, the second cooling matrix 8, the first side sealing wall 12, and the second side sealing wall 13 constitute a mobile crystallizer, and the cavity of the mobile crystallizer has two openings. According to the For the placement positions of the two openings, the upper opening is called the upper opening, and the lower opening is called the lower opening. The first container wall 9, the second container wall 10, the first side sealing wall 12, and the second side sealing wall 13 form a molten metal storage space, and there is only one molten metal storage space The only opening in the molten metal storage ...

Embodiment 2

[0074] Embodiment 2 of the present invention discloses a device for simulating the key transmission mechanism of the twin-roll casting and rolling pool, such as Image 6 , Figure 7 , Figure 8 As shown, the first cooling base 7 and the second cooling base 8 constituting the mobile crystallizer are located above the molten metal storage space, and the first cooling base 7 and the second cooling base 8 are placed in parallel, The first cooling base 7 and the first container wall 9 move in translation at the same speed, the second cooling base 8 and the second container wall 10 move at the same speed, the first cooling base 7 and the second The speeds of the cooling matrix 8 are equal in magnitude and opposite in direction, and the speeds of the first container wall body 7 and the second container wall body 8 are equal in magnitude and opposite in direction.

Embodiment 3

[0088] Embodiment 3 of the present invention discloses a device for simulating the key transmission mechanism of the twin-roll casting and rolling pool, such as Figure 9 shown. The biggest difference between the third embodiment and the first embodiment is that the third embodiment uses the piston 26 to push the molten metal 28 of a certain composition into the cavity of the moving crystallizer. The piston 26 should be considered as a movable wall. When compressed air is used to transfer molten metal from the molten metal supply system into the moving crystallizer cavity, the compressed air should act as a movable wall. In particular, when gravity is used to make the molten metal flow naturally into the cavity of the moving crystallizer, the gravity at this time should be regarded as a movable wall.

[0089] The first cooling base 7 and the second cooling base 8 start to move towards each other when part of the molten metal just enters the moving mold, and the reduction of ...
