As a national strategic pillar industry, the metallurgical industry carries the important mission of ensuring the development of the national economy. Driven by the dual goals of "dual carbon" and intelligent manufacturing upgrades, metallurgical enterprises are undergoing profound changes in equipment intelligence, energy efficiency optimization, and autonomous and controllable supply chains. With the release of the "Standardized Conditions for the Steel Industry (2025 Edition)", the metallurgical industry has accelerated its transformation. Against this background, Sine Electric's low-voltage inverter has become the core choice to replace imported brands with its technological breakthroughs and cost advantages.
In the process of the metallurgical industry's commitment to building an independent and controllable industrial system, Sine Electric has actively participated in the localization cause and played a key supporting role. Through domestic substitution, the company's comprehensive cost can be reduced by 20%-30%.
Sine Electric's EM790 series 1600kW variable frequency cabinet stands out in the application scenarios of the metallurgical industry with its excellent performance. The EM790 series inverter products have been stably operated for more than 100,000 hours in many leading customer companies in the metallurgical field. With the actual operating time, it has effectively verified the reliable quality of domestic equipment and laid a solid foundation for the efficient and stable production of the metallurgical industry.

1.Excellent control performance
Sine Electric EM790 series inverter adopts advanced vector control technology, which can achieve stepless speed regulation of the motor and accurately control the motor speed. It can ensure that the motor can maintain the best operating state under different working conditions. The capacity redundancy selection of key components further ensures the stable output and easy control of the inverter under extreme working conditions during operation.
2.High efficiency and energy saving
As a major energy consumer, the metallurgical industry has always been the focus of energy saving and consumption reduction. Sine Electric's EM790 series inverters reduce energy consumption and improve energy efficiency by optimizing motor operating parameters. In applications, the inverter can adjust the motor speed according to actual working conditions to avoid the motor being in a high-load operating state for a long time, thereby achieving the purpose of energy saving.
3.Stable and reliable
The production environment of the metallurgical industry is harsh, and the reliability and stability of the equipment are extremely high. The EM790 series inverter of Sine Electric adopts modular design and independent air duct design, which can operate stably in harsh environments such as high temperature, high humidity, and dust. At the same time, the inverter has built-in multiple protection functions, such as overcurrent, short circuit, overvoltage, undervoltage, etc., to ensure that the motor is fully protected during operation.
4.High applicability
In the metallurgical industry, the Sine Electric EM790 series inverter also demonstrates good speed regulation performance and adaptability. During the operation of the motor, the speed usually needs to be adjusted according to the process requirements. The Sine Electric inverter has a wide speed regulation range and precise speed regulation accuracy, which can flexibly adapt to changes in process requirements and ensure that the equipment can maintain the best output under different working conditions.
5.Intelligent control
Supports multiple protocols such as Profinet, CanopenEtherCAT, Profibus, Modbus-TCP/RTU, and supports multiple PG cards and IO cards;
The control function of the inverter can be seamlessly integrated with the automation system, which is easy to integrate into the automation system, realize intelligent management, and improve production efficiency and safety.
6.After-sales guarantee
The modular design enables online replacement of key components, reducing downtime by 70%. Sales service centers have been set up in 28 large and medium-sized industrial cities, and more than 100 joint guarantee service units are spread across the country, responding quickly within 24 hours and providing customers with free lifelong online technical support services.
Relying on the technical characteristics of the EM790 series inverters, Sine Electric has set many benchmarks in the domestic substitution of the metallurgical industry. In the future, with the release of policy dividends and the acceleration of technological iteration, Sine Electric will deeply participate in the development of the metallurgical industry: the dual transformation of "intelligent upgrading + green transformation", providing the core driving force for building an independent and controllable industrial system.
