Description

Technical Field

[0001] This utility model relates to the field of hot-rolled steel pipe lifting tools, specifically an automatic hot-rolled steel pipe lifting tool. Background Technology

[0002] Hot rolling is the opposite of cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the recrystallization temperature. During the production of hot-rolled steel pipes, lifting devices are needed to transport the formed pipes. However, in existing automatic lifting devices, the control equipment is located inside the center frame. The finished steel pipes are overheated, and prolonged exposure to heat on the center frame can easily damage internal components. Furthermore, it is inconvenient to adjust the lifting range according to the length of the steel pipe during lifting, affecting the stability of the lifting process. Therefore, improvements to the existing technology are needed. Utility Model Content
