Tianjin Uranus Hydraulic Machinery Co., Ltd.'s heavy-duty rotary cylinders for steel processing equipment are engineered to withstand the extreme conditions of steel mills and foundries. Constructed from heat-resistant alloy steel (such as 42CrMo4 with tensile strength ≥1,100 MPa), these cylinders feature a hardened surface treatment (induction hardening to 58-62 HRC) to resist high temperatures and abrasive environments. The design incorporates a double-lip sealing system with PTFE-impregnated seals, preventing ingress of molten metal splatter and scale. With torque outputs up to 50,000 N·m, they are ideal for driving rolling mill tables, forging presses, and continuous casting rotary tables. The cylinders undergo rigorous testing, including 1,000-hour high-temperature endurance runs at 300°C, ensuring reliable operation in steel processing lines. Custom configurations with water-cooling jackets are available for extreme heat applications.
