Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of driving roller production and transportation, and particularly relates to a conveying device for a continuous casting machine driving roller and a conveying method thereof. BACKGROUND

[0002] The continuous casting machine driving roller (also known as a continuous casting machine driving drum) is an important component in the continuous casting production line, mainly used for pulling the casting blank, and ensuring the stable stretching and movement of the casting blank during the solidification process by transmitting power and controlling speed.

[0003] Specifically, in the continuous casting process, the molten metal is poured into the mold from the furnace and gradually solidifies into a casting blank. The driving roller system of the continuous casting machine contacts the surface of the casting blank and provides traction to smoothly pass the casting blank along the continuous casting line through the cooling zone, the dividing zone and the forming zone. The driving roller mainly performs the following key tasks:

[0004] Pulling the casting blank: the driving roller system transmits external power to the casting blank to pull it out of the casting machine;

[0005] Controlling the speed of the casting blank: the rotation speed of the driving roller controls the speed of the casting blank to ensure the uniformity of the stretching during the casting process and avoid casting defects caused by uneven speed;

[0006] Ensuring a stable stretching process: the driving roller can maintain good contact with the surface of the casting blank to avoid breakage or deformation of the casting blank due to insufficient or excessive friction;

[0007] Adjusting the surface state of the casting blank: appropriate roller pressure and rotation speed help to maintain the smoothness and flatness of the casting blank surface and reduce the occurrence of surface defects.

[0008] However, the existing technology uses manual handling, cart handling, conveying roller handling or conveyor belt handling for the manufacture and transportation of the driving roller. Due to the large weight of the roller, only small and medium-sized driving rollers can be transported using conveyor belt handling, which is limited in transportation means and needs to be improved.
