Rolling Mill Accessories Coiler And Uncoiler & Four Pronged Cone Shaft

In the modern steel rolling production line, the Coiler and Uncoiler, as key auxiliary equipment, together with the four-Pronged Cone Shaft, form an efficient metal coil processing system. This combination is specially designed for hot and cold rolling production lines, capable of processing steel coils with thicknesses ranging from 0.2 to 20mm and widths from 600 to 2000mm, with a maximum coil weight of 45 tons, meeting international standards such as ASTM and DIN.
The intelligent winding system adopts a hydraulic automatic centering device, with a deviation correction accuracy of ±0.5mm. It is equipped with a tension closed-loop control, with a fluctuation range of < ±1%. The modular design supports rapid roller changing (< 15 minutes).
Innovative four-claw conical shaft structure, forged from 42CrMo alloy steel, surface high-frequency quenching treatment (HRC58-62), four-claw synchronous expansion mechanism, tensioning force up to 1200kN, taper 1:30 optimized design to ensure the core is undamaged.
Collaborative advantage: When conducting joint operations, the flatness of the coil end face is less than 2mm/m, and the speed synchronization with the main rolling mill is achieved through PLC (response time < 50ms).
