New Threaded Rod Induction Hardening and Tempering Machine

Addressing Long-Standing Pain Points in Threaded Rod Heat Treatment

High-strength threaded rods are critical components for mining support, construction anchoring and heavy machinery fastening. Traditional furnace heat treatment often brings obvious drawbacks: uneven heating, heavy oxidation scale, unstable hardness and large deformation on screw threads. Once threads crack or hardness fluctuates, finished products will fail fatigue tests and bring huge safety risks for end users. Many fastener manufacturers are eager to find continuous, controllable and low-energy heat treatment equipment to lift product qualification rate. Focusing on this market demand, Forever Electromechanical officially launches its upgraded threaded bar induction hardening and tempering equipment, bringing a mature induction heat treatment solution for global fastener and anchoring manufacturing sectors.

IGBT Induction Core Achieves Precise and Uniform Heating

The new machine adopts advanced IGBT energy efficient induction power supply as its core. Different from external heating modes, induction heating generates heat inside the workpiece directly, delivering fast temperature rise and outstanding thermal efficiency. Multi-point infrared temperature sensors cooperate with PLC closed-loop control system to monitor real-time temperature along the rod body and threaded section. The system automatically adjusts power and line speed according to material grade, diameter and technical requirements. It keeps temperature fluctuation within a narrow range, prevents overheating on thread crests and insufficient hardening at thread roots. The integrated design completes hardening, quenching and tempering in one continuous flow, avoiding secondary clamping error and greatly protecting thread profile from damage.

Wide Compatibility and Stable Continuous Production

This threaded rod induction hardening and tempering machine supports multiple steel grades including 45# steel, 40Cr and 42CrMo. It covers a wide range of rod diameters and can match different capacity requirements from small batch trial production to large-volume mass manufacturing. Optimized roller conveying structure ensures straight feeding, reduces bending deformation during thermal processing. The whole line can run stably for 24-hour continuous production with low failure rate and simple daily maintenance. Compared with gas furnace or resistance furnace, it cuts unit energy consumption obviously, lowers oxide scale and reduces subsequent polishing workload. Finished threaded rods gain balanced hardness and toughness, with stable metallographic structure and longer fatigue service life, fully meeting international standards for anchor bolts and high-strength threaded bars.

Intelligent Operation and Customized Service for Global Clients

Forever Electromechanical reserves multi-language operation interface for overseas users. Technicians can store multiple process recipes on the control panel. Operators can switch parameters quickly when changing workpiece specifications, which shortens setup time. The equipment supports remote data viewing and fault diagnosis, bringing convenient after-sales support. The engineering team provides tailor-made layout design, on-site installation, commissioning and operator training services. Till now, Forever’s threaded bar induction heat treatment line have been delivered to the Middle East, Southeast Asia, Europe and other regions, winning consistent recognition from fastener factories and anchoring material producers.

Outlook: Low-Carbon Intelligent Heat Treatment as Main Direction

Against the background of global manufacturing transformation toward energy saving and emission reduction, induction heat treatment becomes an important low-carbon alternative. Forever Electromechanical will keep investing in induction heating R&D, optimizing coil structure, power module and automatic detection functions. The company will launch more targeted heat treatment equipment for threaded rods, sucker rods, seamless pipes and grinding balls. By combining stable equipment quality and localized technical service, Forever Electromechanical aims to help more metal processing enterprises upgrade production lines, improve product competitiveness and realize sustainable, intelligent manufacturing.
