High Temperature Hydraulic Cylinder

High-temperature hydraulic cylinders are engineered to withstand extreme thermal environments while maintaining precise operation, featuring specialized materials and cooling systems that enable reliable performance in 200-500°C applications. These robust actuators incorporate ceramic-coated piston rods, stainless steel alloy bodies (310S/316L), and fluorocarbon-based sealing systems that resist degradation under continuous heat exposure. Water-cooled gland assemblies and thermal barrier technologies protect critical components, allowing the cylinders to deliver consistent forces from 1-500 tons even in radiant heat conditions near molten metal. Their advanced designs include heat-dissipating fins and graphite-impregnated bushings that provide dry-running capability during cooling system interruptions, while integrated temperature sensors enable real-time thermal monitoring.     In steel production, these cylinders precisely control continuous casting mold oscillation and rolling mill…
