Intelligent Empowerment for Quality Improvement and Carbon Reduction! Smart Steel Billet Heating and Reheating Furnace Leads Digital Transformation of Steel Heat Treatment

The steel hot processing industry has witnessed a new round of intelligent technological upgrades. The newly developed intelligent steel billet heating and reheating furnace features digital regulation, precise temperature control and low-carbon energy-saving performance. It effectively solves the long-standing industry pain points of traditional equipment, including high energy consumption, uneven heating, severe oxidation loss and heavy reliance on manual operation. As core equipment for steel rolling and forging production lines, it strongly supports the high-quality, green and digital transformation of the steel manufacturing sector.

As a key energy-consuming and process-critical device in steel production, the traditional automatic billet induction reheating furance mainly relies on workers’ experience to adjust combustion parameters and furnace temperature. Affected by fluctuating working conditions and inconsistent manual operation, it commonly causes large internal and external temperature differences on steel billets, thick oxide scales and excessive fuel waste. Relevant statistics show that traditional heating furnaces account for over 56% of the total energy consumption of steel rolling lines, leading to high carbon emissions per ton of steel. Moreover, its unstable heating accuracy fails to meet the production standards of high-end steel products, restricting the capacity and quality upgrading of steel enterprises.

Upgraded with cutting-edge intelligent technologies, the new-generation heating and reheating furnace is equipped with a full digital PLC control system, high-precision infrared temperature measurement array and AI combustion optimization algorithm, forming a closed-loop full-process intelligent regulation system. The device can collect more than 30 operating parameters in real time, including furnace pressure, flue gas temperature, oxygen content and fuel flow. It responds to working condition changes within 0.3 seconds and dynamically optimizes the air-fuel ratio and heating parameters, completely getting rid of dependence on manual experience. The temperature difference of heated steel billets is stably controlled within ±5℃, ensuring uniform and standardized heat treatment quality.

The intelligent system delivers prominent advantages in energy conservation, emission reduction and production efficiency improvement. Equipped with a staged flue gas waste heat recovery system and low-nitrogen combustion technology, the furnace greatly reduces heat energy loss. Actual operation data proves that its energy consumption per ton of steel is 12% to 15% lower than traditional equipment, with nitrogen oxide emissions meeting ultra-low emission standards. Meanwhile, the intelligent constant-temperature heating mode effectively reduces surface oxidation and burning loss of steel billets, improves the finished product rate of steel materials and cuts production and waste costs significantly.

In addition,steel billet rolling induction heating machine integrates digital twin visual monitoring and intelligent fault self-diagnosis systems. It can simulate the real-time heating state inside the furnace and predict potential operational risks, with a fault diagnosis accuracy rate of 99.6% and a downtime rate lower than 0.1%. The integrated automatic feeding, heating, temperature control and discharging process minimizes manual intervention, reduces labor costs and operational errors, and perfectly adapts to large-scale and continuous steel hot processing production lines.
