Drill Rod Upsetting Induction Heating Equipment

This drill rod upsetting induction heating equipment is the dedicated thermal unit for the drill pipe upsetting process, employing medium-frequency induction heating to deliver fast, precise localized heating to the pipe body ends. It prepares workpieces with uniform temperature and thorough softening ahead of hydraulic upsetting forging, serving as the critical upstream station that directly determines forming quality.
The induction heating system heats pipe ends to the optimal upsetting temperature within seconds, with the heat-affected zone precisely confined to the upset region at the end. Thermal conduction to the pipe body beyond the forming zone is effectively prevented, fully preserving the strength and toughness of the remaining pipe — ensuring the overall mechanical performance of the drill rod is unaffected.
Induction coils are custom-designed to match the outer diameter, wall thickness, and upset zone length of each pipe specification. Concentrated and uniform heating across the target area ensures consistent temperature distribution from the outer wall through to the inner wall of the end section, preventing uneven deformation or end cracking caused by excessive inner-outer temperature differentials, and safeguarding dimensional accuracy and surface quality at the source.
A closed-loop infrared temperature monitoring system continuously tracks the heating temperature of the pipe end in real time. Any deviation from the set process temperature triggers automatic power output adjustment, effectively preventing overheating and overburning, ensuring highly consistent discharge temperatures across every pipe, and guaranteeing stable and repeatable upsetting process parameters throughout batch production.
Digital phase-lock technology enables automatic frequency tracking without manual adjustment, seamlessly adapting to different induction coil specifications. Operating without high-voltage hazards, the equipment runs continuously and safely for 24 hours. Significant energy savings over conventional gas heating, combined with no open flames or fume emissions, deliver a clean working environment that meets modern green factory standards.
