Forever Electromechanical Upgrades Intelligent Sucker Rod Induction Quenching & Tempering Furnace to Upgrade Oilfield Component Heat Treatment
With global oil and gas exploration moving toward deep wells and harsh working conditions, sucker rods bear alternating tensile loads underground, putting forward stricter standards for surface hardness, overall toughness and dimensional stability. Traditional sucker rod induction hardening and tempering machine suffers unstable temperature control, large hardness deviation, high energy consumption and poor automation, which have become major bottlenecks restricting oil pipe manufacturers to produce high-quality sucker rod products. Forever Electromechanical, a professional supplier of induction heat treatment equipment, has launched a fully intelligent integrated sucker rod induction quenching and tempering furnace, relying on self-developed digital IGBT frequency conversion technology and full closed-loop intelligent control system, bringing comprehensive performance upgrades for oilfield metal processing enterprises.
Traditional sucker rod heat treatment lines adopt fixed power output and manual parameter adjustment. During continuous production, temperature difference between rod body and thread section can reach over 35°C, resulting in inconsistent mechanical properties; frequent manual intervention increases labor costs, and lack of real-time data monitoring makes quality tracing impossible. In addition, outdated power conversion structures lead to low energy utilization, while non-modular equipment design causes long maintenance downtime once coils or power units break down. These pain points seriously affect product yield and factory operating profits.
Forever Electromechanical’s new intelligent
sucker rod induction heat treatment machine takes intelligent digital technology as the core to realize full-process automatic control. The equipment is equipped with multi-point infrared real-time temperature measuring sensors, forming a dual closed-loop regulation system combining quenching heating and tempering heat preservation. It independently adjusts output power according to sucker rod length, diameter and raw material carbon content, controlling the overall hardness fluctuation within ±1.5 HRC and effectively avoiding fracture failure of finished sucker rods in service.
The core power unit adopts the latest SiC IGBT digital variable frequency power supply, which automatically matches heating power according to the running speed of the production line. Compared with conventional silicon controlled power supply equipment, the unit energy consumption is reduced by 29%, greatly cutting long-term electricity expenditure for manufacturers. The segmented independent induction coil design targets the threaded key stress area of sucker rods, realizing differentiated strengthening heating, solving the common industry problem of insufficient hardness at rod threads.
In terms of intelligent management, the whole furnace is equipped with industrial PLC+DSP dual-core control system and IoT remote cloud monitoring module. All heating speed, quenching water pressure, tempering temperature and energy consumption data are automatically stored, supporting one-click export of production quality reports to achieve full batch traceability. The built-in intelligent fault prediction system monitors coil temperature, cooling water flow and power operating status in real time; it sends early warning reminders before potential failures occur and displays fault location codes, cutting troubleshooting time by more than 70%.
Modular assembly design is another highlight of the intelligent furnace. All power cabinets, heating coils and cooling units are independent modules. Single damaged components can be replaced without stopping the whole line, greatly improving production continuity. The production line supports seamless switching of various specifications of sucker rods, and all process parameters can be stored in the system for one-click calling, lowering the technical threshold for operators.
At present, this sucker rod induction heat treatment line has completed stable trial operation at multiple domestic and foreign oil accessory manufacturers. Customer test data shows that the product qualification rate of sucker rods has increased from 92% to 99.7%, while comprehensive production costs drop significantly.
Forever Electromechanical’s R&D director stated that the enterprise will continue to deepen intelligent induction heating technology research, customize targeted heat treatment equipment for various oilfield special parts, and help global oil accessory processing factories realize low-carbon, unmanned and high-quality intelligent production.
