TECHNICAL FIELD
[0001] The present application relates to the technical field of metal continuous casting traction, in particular to a vertical traction device for alloy continuous casting. BACKGROUND
[0002] In the modern alloy rod processing field, continuous casting technology has become the core process for preparing high-precision and high-performance alloy rods due to its high efficiency, energy saving and consumption reduction, and high automation. The vertical traction device, as the core hub of the continuous casting production line, its running performance is directly related to the forming precision of the alloy rod, production efficiency and long-term stable operation of the equipment.
[0003] The core components of the existing vertical traction device mainly include a crystallizer and a traction mechanism. In the continuous casting process, the molten metal in the crystallizer in a molten state flows through the internal graphite mold, and is rapidly solidified into an alloy rod by the efficient cooling effect of the crystallizer. The traction mechanism adopts a traditional rigid fixed structure design, that is, the traction wheel is installed on the rack through a fixed shaft, the traction wheel is driven to rotate by a motor, and the solidified alloy rod is continuously and stably pulled out of the crystallizer and transported to the subsequent processing link by relying on the friction force generated between the traction wheel and the surface of the alloy rod, thereby realizing the continuous production of the alloy rod.
[0004] However, due to the inherent limitations of the rigid fixed structure, the surface of the traction wheel is prone to wear due to friction after long-term high-frequency operation. As the wear intensifies, the friction coefficient between the traction wheel and the alloy rod decreases significantly, not only causing the guiding precision of the alloy rod in the traction process to decrease substantially, causing defects such as casting blank deviation and bending, but also causing the traction power loss to increase, seriously affecting the stability of the continuous casting production and the product quality, and frequent replacement of worn parts also greatly increases the equipment maintenance cost and downtime.
