Product Overview
TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly introduces the Electroslag Furnace Transformers. These advanced units are designed for the precise melting and refining of steel produced by conventional smelting methods, enabling the production of high-quality materials such as aviation bearing steel, high-temperature alloys, resistance alloys, precision alloys, and various non-ferrous metals. They also support the creation of large-scale alloy steel ingots, massive flat ingots or slabs weighing hundreds of tons, and other specially shaped castings through electroslag furnace power supply.
Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from pioneering arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Embracing Industry 4.0 principles, Jinguan Electric drives core competitiveness through continuous innovation, with TiraThai serving as its premier brand for electroslag furnace transformer solutions. This sub-brand channels Jinguan Electric's expertise into customizable, high-efficiency transformers that differ from electric arc furnace types, focusing on low no-load voltage and small impedance for arc-free electroslag processes post-initial stage. Certified by UL, CUL, CCC, CQC, CTQC, CE, and SGS, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, ensuring superior performance and sustainability.
The TiraThai Electroslag Furnace Transformers are available in single-phase (generally preferred) and three-phase configurations, with voltage regulation on the low-voltage side via series connection. Adjustment methods include no-excitation no-load, excitation no-load, or on-load voltage regulation, all controlled by a switch on the high-voltage coil. Customizable for voltage, frequency, and regional specialties, they integrate seamlessly into metallurgical workflows. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering transformers that optimize refining efficiency and material quality for advanced industrial applications.

This specialized design makes TiraThai's Electroslag Furnace Transformers indispensable for high-precision metallurgy worldwide.
Key Features and Engineering Excellence
TiraThai's Electroslag Furnace Transformers are engineered for precision and reliability, featuring low no-load voltage and small impedance voltage to support arc-free electroslag processes after the initial arcing stage. The single-winding configuration ensures stable power supply to consumable electrodes, minimizing variations in slag pool dynamics and reducing defects in refined materials. Voltage regulation on the low-voltage side via series connection provides flexible adjustment, with options for no-excitation no-load, excitation no-load, or on-load methods controlled by a high-voltage coil switch for seamless operation.
The core utilizes high-permeability silicon steel with optimized stacking for low losses, paired with oxygen-free copper windings for high conductivity and thermal stability. Oil immersion facilitates superior cooling (ONAN), maintaining Class A insulation under overloads up to 120%. Jinguan Electric's automated production—featuring precision winding, vacuum oil-filling, and AI inspections—guarantees defect-free assembly, with robust enclosures for weather resistance (IP54 rated).
Compared to arc furnace transformers, TiraThai electroslag units offer 15-20% better arc control and energy efficiency, extending electrode life and improving yield rates. Optional features like integrated monitoring and surge protection enhance safety. These attributes not only meet but exceed IEC 60076 and GB 1094 standards, providing metallurgists with a transformer that ensures consistent, high-quality output.
