FOMET's radar systems are now widely utilized to enhance metal level control in its automatic pouring furnaces. These radar systems have been successfully installed in numerous FOMET furnaces across Italy, Europe, and around the world, including those at Renault, Tupy, and Brembo.
The radar system replaces the previous laser measurement technology, though the electrode remains as a rare backup for safety.
Following initial trials and subsequent field tests in 2021 with trusted foundries, FOMET successfully installed and integrated its first radar system into an existing FOMET casting furnace in November 2021.
In 2022, FOMET continued expanding its radar system installations, integrating 5 systems: one in the first quarter, one in the second, one in the third, and two in the final quarter.
In 2023 and 2024, additional FOMET radar systems were installed and integrated into casting systems for more of their loyal customers.
This article is intended to inform customers that while the radar system is not exclusive to FOMET, it must be properly parameterized and integrated into the pouring system's control logic to ensure optimal performance. Therefore, it is not recommended to purchase the radar system without full integration by FOMET.
As with any equipment, complete integration is essential for the system to function at its best.
FOMET radar sensors are designed for non-contact metal level measurement. These sensors deliver reliable measurements even in challenging conditions, such as the presence of insulating blankets, slag, dust, and noise, without being affected by deposits or condensation.
Measuring Principle
The measuring instrument sends short microwave signals through the antenna system towards the medium. When these signals hit the iron surface, they are reflected back and received by the antenna system. The time taken for the signal to travel from transmission to reception is directly proportional to the level in the pouring siphon.
A unique time-stretching technique ensures accurate and reliable measurement of the very brief transmission times, converting them into level readings.
The radar sensors operate with low emission power within the C and K band frequency range.
Benefits
Non-contact radar technology offers exceptional measurement accuracy. The system is unaffected by changes in iron properties or process conditions such as temperature, pressure, or heavy dust generation. Its user-friendly setup eliminates the need to fill or empty the channel, saving time, while the sensors require no maintenance.
The radar system is housed in a protective casing cooled by a vortex air system and is mounted on a special bracket positioned above the pouring channel.
