Recently, a certain metal processing enterprise has taken the lead in completing the upgrade of its production equipment and introduced a new generation of medium-frequency induction heating furnaces for the flat steel heating process. The high-efficiency induction heating furnace is equipped with an intelligent automatic feeding and discharging system, which not only completely changes the manual reliance predicament of the traditional heating mode, but also achieves a triple breakthrough in safety, efficiency and low cost in the flat steel heating process, providing a strong reference for the intelligent transformation of the metal processing industry.
In the traditional flat steel heating production scenario, manual loading and unloading are one of the core processes. Operators need to frequently approach the high-temperature furnace body, feed the flat steel bars into the furnace one by one, and then manually remove them after heating is completed. This not only involves high labor intensity but also poses safety hazards such as high-temperature burns and material bumps. Meanwhile, the instability of manual operation can easily lead to uneven feeding rhythms, affecting the uniformity of heating and thereby reducing the product qualification rate.
The core highlight of the high-efficiency induction heating furnace introduced this time lies in the installation of a customized automatic feeding and discharging system, which realizes unmanned intervention throughout the entire process of flat steel heating. This system adopts servo motor drive and precise positioning technology. It can flexibly adjust the feeding speed and spacing according to the specification parameters of the flat steel, and smoothly and orderly feed the flat steel into the induction heating coil. After heating is completed, qualified workpieces are quickly conveyed to the next process through an automated discharging mechanism, without the need for manual contact with high-temperature materials throughout the entire process.
In addition to significantly reducing labor costs, the improvement in heating efficiency and safety of this medium-frequency induction heating furnace is equally remarkable. Relying on the technical advantages of medium-frequency induction heating, heat is directly generated inside the flat steel, achieving uniform heating penetration throughout the entire cross-section. The temperature difference between the core and the surface is controlled within 30℃, effectively avoiding the problem of "overheated surface and incomplete core penetration" in traditional heating methods. The product heating qualification rate has been increased to over 99%. Meanwhile, the heating speed of the high-efficiency induction heating furnace is more than three times that of traditional coal-fired furnaces, perfectly meeting the demands of mass production.
In terms of safety, the fully automated process enables operators to completely stay away from high-temperature furnaces and open flame environments, fundamentally eliminating safety risks such as scalding and fire. In addition, the high-efficiency induction heating furnace adopts a fully digital control system, combined with an infrared temperature measurement closed-loop monitoring function, which can precisely control the heating temperature in real time, avoiding abnormal situations such as over-temperature and under-temperature. At the same time, the heating furnace is equipped with a complete fault alarm mechanism, further ensuring production safety and stability. Compared with traditional coal-fired and gas-fired heating furnaces, this induction heating furnace is electrically heated throughout the process with no exhaust emissions and a noise level below 60 dB. The heating furnace not only meets the strict requirements of environmental protection departments but also significantly improves the working environment in the workshop.
The successful application of the medium-frequency induction heating furnace this time not only brought significant economic benefits to the enterprise, but also marked its leap from "traditional human-driven" to "intelligent technology-driven" in the field of flat steel processing. Industry insiders say that as intelligent and automated technologies continue to penetrate the metal processing industry, such efficient, safe and environmentally friendly heating equipment will become the mainstream choice for industry transformation, promoting the metal processing industry to move towards high-quality development.
