[0021] Operating principle: This device is located on a platform in front of the ladle. When a new sprue needs to be installed, the new sprue is placed on the circular collar 14. Then, the first rotary motor is started to drive the first rotating disk 4 to rotate, causing the horizontal long beam to align with the installation position at the bottom of the ladle. Then, the first drive motor 6 is started, causing the lead screw to rotate. The rotating lead screw drives the lead screw nut to move, ultimately driving the slider 9 forward. During the sprue's forward movement, when it passes through the gap between the tundish and the ladle, the second drive motor is activated to drive the long cylindrical rod 12 to rotate, thereby causing the sprue to flip, allowing the sprue to smoothly pass through the gap between the tundish and the ladle. After moving to the installation position, the second drive motor reverses, allowing the sprue to return to a vertical state. Then, through the cooperation of the first drive motor and the second rotary motor, the position of the sprue is finely adjusted so that it is directly below the installation position. Then, the hydraulic cylinder is started to drive the lifting column 2 to rise, so that the sprue aligns with the installation position at the bottom of the ladle. At this point, the sprue installation is complete. When it is necessary to replace the nozzle, the hydraulic cylinder retracts the piston rod, causing the old nozzle to detach from the installation position. Then, the first drive motor moves the nozzle away from the installation position, and the second drive motor moves the nozzle to tilt and smoothly pass through the gap between the tundish and the ladle until the nozzle leaves the bottom of the ladle. Then, the old nozzle is removed, and the new nozzle is inserted into the circular collar. Then, the installation of the new nozzle is carried out.
