　　Next, the manufacturer will introduce to you what... is. Medium-frequency furnace

　　The medium-frequency furnace is an induction heating device used for heating metals. It is widely employed in the pre-forging, casting, and tempering heat-treatment industries, playing a key role as the primary heating equipment in the mechanical thermal processing sector. So, what exactly does a medium-frequency furnace system consist of? Our editor provides a detailed introduction to the medium-frequency furnace heating system.

　　1. According to Medium-frequency furnace The system’s power supply equipment—transformers and their cooling media—can be categorized into two types: dry-type transformers and liquid-cooled transformers. In the medium-frequency furnace industry, we often use medium-frequency furnace rectifier transformers, which significantly outperform conventional transformers in terms of overload capacity and anti-interference performance.

　　2. The intermediate-frequency power supply and the intermediate-frequency power supply cabinet are the core components of the intermediate-frequency furnace system. The intermediate-frequency power supply consists of a rectifier and an inverter, a capacitor bank, thyristors, AC contactor assemblies, water-cooled cables, and other components. 3. The capacitor cabinet in the intermediate-frequency furnace system serves to provide reactive power compensation for the induction coil. As is easy to understand, the size of the capacitors directly affects the equipment’s power output. It’s important to note that the capacitors used in parallel-connected equipment are a type of resonant capacitor (electrothermal capacitor). In addition to series-resonant capacitor components (capacitors), filtering capacitors are preferred; this is also stipulated by national standards and can be used to determine whether the equipment is configured in parallel or in series.

　　4. The furnace body of the medium-frequency furnace, Medium-frequency furnace In a metal heating furnace—specifically, a medium-frequency heating furnace—the furnace body is referred to as a sensor or induction coil; in a metal melting furnace—specifically, a medium-frequency melting furnace—it is called a steel-shell furnace body or an aluminum-shell furnace body.

　　5. The cooling water and cooling water control system are indispensable and critically important components of the medium-frequency furnace system. Indeed, the performance of the cooling system directly determines the failure rate of the medium-frequency furnace system. Currently, there are three commonly used cooling methods for medium-frequency furnace systems: traditional pool cooling, open cooling towers, and closed cooling towers. Pool cooling occupies a large amount of space, requires significant quantities of cooling water, suffers from poor water quality, and is prone to scaling; thus, it is rarely used today. Open cooling towers offer high cooling capacity, low costs, and moderate land requirements. We are currently using some furnace units with capacities exceeding 10 tons. However, due to issues with the quality of the cooling water, we do not recommend using them with power cabinets. Closed cooling towers, by contrast, keep the circulating water entirely enclosed in a sealed system, effectively isolating it from external environmental influences and ensuring excellent water quality. They also feature low water consumption, compact footprint, and high cooling capacity, making them one of the most widely adopted cooling methods today.
