Description

Technical Field

[0001] The present application relates to the technical field of continuous casting equipment, and in particular to a continuous casting guide device. Background Art

[0002] The guide section of continuous casting is very important in the continuous casting process of steelmaking. The guide section is located in the continuous casting arc section area, and plays the role of carrying the dummy rod and the continuous casting billet during production. When sending the dummy rod, the guide section carries the dummy rod sent by the straightening machine, and sends the dummy rod to the crystallizer according to a certain trajectory. During production, the guide section sends the billet to the fire cutting machine and roller table according to a certain trajectory.

[0003] The guide device of the guide section of the continuous casting equipment currently used mainly consists of a roller support, a roller and a limit device. During the process of feeding the guide ingot, since the roller surface width of the roller is larger than the cross-sectional width of the guide rod, it will move left and right, resulting in the ingot rod being unable to be accurately sent to the crystallizer. In the process of drawing steel, since the roller surface width of the guide section roller is larger than the cross-sectional width of the billet, the billet will move left and right in the axial direction of the roller, resulting in the billet entering the straightening machine and the fire cutting machine being misaligned; at the same time, since the inner arc limit device is high and fixed, the billet will deviate from the moving guide section roller and deviate toward the inner arc when there is a large billet drawing resistance, which will cause uneven cooling of the billet and cause the billet to be deformed, which is not conducive to billet discharge and affects the continuous casting process.

[0004] In view of this, the present application aims to provide a continuous casting guide device to better solve the above-mentioned technical problems. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a continuous casting guide device, which can solve the technical problem of adaptive guidance of the continuous casting guide section.

[0006] An embodiment of the present application provides a continuous casting guide device, including a support frame, a roller structure, a V-shaped pressure roller structure and a counterweight. The support frame is provided with a fixed seat and a guide seat, the guide seat is provided with a connecting plate, the roller structure is installed on the fixed seat, the V-shaped pressure roller structure is installed on the guide seat and is spaced directly above the roller structure, and the counterweight is arranged at the top of the connecting plate.

[0007] Furthermore, the support frame is provided with a limiting groove for installing the guide seat, which is used to install the guide seat and limit the highest and lowest positions of the guide seat.

[0008] Furthermore, the guide seat is rotatably hingedly arranged on the support frame and is located above the fixed seat.
