[0029] Working principle: The support crossbar 3 is horizontally inserted into the inner side of the through-slot 2 near the top of the center line on the side of the main support block 1. A transmission gear 16 is engaged with the top surface of the through-slot 2. The transmission motor 6 is fixedly located at one end of the side of the main support block 1, and its output end extends and is fixedly connected to the center of the transmission gear 16. When the transmission motor 6 is started, it drives the transmission gear 16 to rotate. The bottom surface of the transmission gear 16 extends into the top tooth groove 4 horizontally opened on the top surface of the support crossbar 3, thereby driving the support crossbar 3 to move horizontally within the through-slot 2. The end mounting blocks 5 at both ends of the support crossbar 3 can be used to connect other auxiliary equipment or for fixation.

To achieve the flipping of the main intermediate package 14, the flipping motor 10, fixed on one side of the rotating base block 9, is activated. Its output end extends horizontally and is fixedly connected to one end of the flipping shaft 21. The flipping shaft 21 drives the telescopic connecting rod 11 to rotate, thereby causing the end support block 12 and the main intermediate package 14 to flip around the flipping shaft 21. At the same time, the adjusting motor 13, fixed on one side of the end support block 12, is activated. Its output end extends horizontally and is fixedly connected to one end of the side shaft 22, allowing for fine-tuning of the angle of the main intermediate package 14 within the end support block 12. Throughout the entire operation, the main support block 1 and its related connecting structures provide stable support for the main intermediate package 14. The mineral fiber layer 23 fixedly installed on the inner wall of the main tundish 14 plays an important role. The mineral fiber has excellent heat insulation, heat preservation and reinforcement properties. During operation, it can effectively reduce heat loss, improve the temperature stability of molten steel in the tundish, and at the same time enhance the structural strength of the working layer of the tundish and extend its service life.
