Key Features and Engineering Excellence
TiraThai's electroslag furnace transformers are engineered with cutting-edge features that enhance process control, safety, and efficiency in remelting operations. A standout capability is the realization of computer-controlled electroslag furnace remelting, integrating seamlessly with automation systems for precise parameter adjustments. The high-precision weighing system, combined with on-load voltage regulating transformers, ensures accurate material monitoring and power delivery, minimizing variations in the remelting process. The coaxial high-current power supply system delivers robust, stable output to the electrode, supporting high-throughput production without voltage drops.
The high-precision X-Y electrode adjustment system allows for fine-tuned positioning, optimizing slag pool dynamics and reducing defects in castings. An airtight inert gas shield protects the melt from oxidation, while the electrode tip preheating device accelerates startup and improves initial melt quality. Structurally, the core utilizes high-grade grain-oriented silicon steel with automated 45° full miter joints and punch-free processing, bound by fiberglass-free adhesive tape for minimal losses and enhanced mechanical stability. Coil technology employs an advanced main-longitudinal insulation structure with optimized winding designs, providing superior short-circuit and overload capacity—up to 150% for short durations—essential for the dynamic loads of electroslag furnaces.
These transformers exhibit high efficiency with minimal no-load and load losses, ensuring energy savings of 10-20% compared to legacy models. Safe and reliable operation is guaranteed through robust enclosures, pressure relief systems, and integrated fault detection, aligning with Jinguan Electric's rigorous quality protocols. Customizable impedance options—via series reactors or HV reconfiguration—adapt to specific furnace demands, while the overall design promotes low noise (under 60dB) and compact footprints for industrial integration. Jinguan Electric's automated production lines, including precision core cutting and vacuum drying, deliver defect-free units ready for global deployment.
These features not only meet but exceed international benchmarks, empowering metallurgists with tools for consistent, high-yield production of premium alloys and castings.
