Rectifiers are widely used in the metallurgical industry, mainly in the following aspects:

electric arc furnace
Smelting process: During the smelting process of the electric arc furnace, the rectifier converts alternating current into direct current and supplies it to the electrodes in the electric arc furnace, which generates high heat energy by generating arcs to melt the metal. For example, three-phase rectifiers are widely used in electric arc furnace power systems to ensure continuous and stable power supply.
Energy saving and efficiency improvement: The use of high-power rectifiers can significantly improve energy efficiency and reduce energy consumption, thereby reducing production costs.

electrolysis process
Non-ferrous metal electrolysis: Rectifier is used in the electrolysis process of non-ferrous metals such as copper, lead, tin, bismuth, antimony, silver and so on. For example, electrolytic copper foil, electrolytic polishing, electrolytic purification and other processes all require rectifiers to provide stable DC power.
Hydrogen production by electrolysis of water: In the process of hydrogen production by electrolysis of water, the rectifier also plays an important role in converting alternating current into direct current to achieve efficient electrolysis reaction.

induction heating
Material heating: In the metallurgical process, rectifiers are also used in induction heating equipment to provide stable DC power for heating metal materials.

Stabilize the power grid
Power grid security: In the metallurgical industry, rectifiers can also be used for security and stability control of the power grid. For example, when the frequency or voltage of the power grid decreases, the rectifier can control the conduction angle of the thyristor to reduce the production current, thereby reducing the load and avoiding losses caused by a complete power outage.

Environmental protection and energy saving
High efficiency and energy saving: Modern high-frequency switching power supply rectifiers have the characteristics of high efficiency and energy saving. They adopt advanced switching power supply technology and intelligent control technology to keep the system in the most efficient working state.
Reduce pollution: The design of the rectifier can reduce interference to the power grid and reduce the generation of power harmonics, thereby reducing environmental pollution.
