The function of rectifiers for rare earth smelting

The rare earth smelting rectifier is the "power heart" of the rare earth smelting system. Its core function is to efficiently convert alternating current (AC) transmitted from the power grid into direct current (DC) that meets the requirements of smelting processes. Through stable control, quality optimization and intelligent adaptation, it ensures the continuity, stability and efficiency of the smelting process for rare earth metals, alloys and compounds.

In rectifiers (especially industrial-grade rectification equipment requiring medium-high frequency and high-precision control, such as those used in rare earth smelting, electrolytic chemical engineering, and other scenarios), the IGBT (Insulated Gate Bipolar Transistor) is a core power switching device and the key to ensuring the efficient, stable, and reliable operation of rectifiers.

In the electrical system of a rectifier, the air circuit breaker (ACB) (also known as an air blast circuit breaker) is a core low-voltage power distribution and safety protection component, whose primary function is to "ensure the electrical safety of the rectifier's main circuit as well as the upstream and downstream equipment"

The three-phase bridge (three-phase rectifier bridge) is a core circuit unit for realizing electrical energy form conversion. Its primary function is to efficiently and stably convert the three-phase alternating current (AC) input from the industrial power grid into direct current (DC) that meets the load requirements, while adapting to the high-power and high-precision operation demands of the rectifier.
