South Korean startup EXCELLO, in collaboration with Sumitomo Shoji Machinex Corporation, is set to introduce a real-time monitoring system for refractory materials used in steelmaking. This partnership marks a significant step for both companies, as the system will be marketed as a solution for ensuring stable operations and improving energy efficiency in steel production.
EXCELLO, founded in 2017, brings its expertise in digital transformation for extreme environments to the table, with advanced technology that enables continuous temperature monitoring across entire furnace surfaces. Unlike traditional thermocouples, which measure temperature at a single point, EXCELLO’s sensors are attached around the full circumference of converter and electric furnaces, allowing comprehensive monitoring.
After conducting a Proof of Concept (PoC) trial in Japan last year, Sumitomo Shoji Machinex confirmed the effectiveness of the technology and has now begun formal sales activities, targeting Japanese steelmakers. The company plans to leverage the Sumitomo Group’s extensive network to introduce the system not only in Japan but also to subsidiaries in Thailand and Taiwan.
Steelmakers have shown significant interest in this monitoring system as it enhances safety by preventing refractory failures and optimizing energy consumption. Several inquiries have already been made, particularly for use in blast furnaces, electric furnaces, ladles, and other key components in steel production. By placing sensors around the furnace’s perimeter, operators can monitor temperature changes in real time, enabling preventive maintenance and energy savings.
Hidehiko Sezose, Managing Executive Officer and General Manager of the Iron, Steel & Non-Ferrous Plant Division at Sumitomo Shoji Machinex, stated, “By visualizing temperature fluctuations across the furnace surface, we can identify unnecessary energy consumption and wear, leading to extended refractory service life and enhanced operational efficiency.”
