Finetek #1: Radar 10 GHz FMCW sensor used in metallurgy environments up to 633°C

Zinc is the fourth most commonly used metal, after iron, aluminum, and copper. At the zinc processing plant, zinc will first be reduced by dry heat treatment, including distillation, or hydrolytic methods, including electrical extraction, firing, osmosis, or cleaning. In steel mills, it is common to use aluminum zinc refining furnaces to control the cleaning and formation of super alloys. Melting metals are usually at 633°C, but in the past it was difficult to track this liquid level.

FineTek has solved problems for some steel mills as follows: JFR is mounted 2m high on molten surfaces (45% Zinc & 55% aluminum), and is especially adjusted, setting the measuring range to keep accuracy within the desired limit, measuring only 300 mm with a +/-2mm error.

This level monitoring allows the operating house to remotely check the process via PC/NB/mobile phone, in which the condition of the metal ball residue is stuck at the exit of the refining furnace, avoiding having to approach this dangerous area regularly. Besides, other challenges of radar sensors in general are very high vibration and the problem of electrolyt compatibility born from aluminum-zinc resymable furnaces. The FineTek JFR 100 passes all U.S. EMC Class A and MIL-STD-202F special tests for military vibration esthest, which can easily operate in this harshest environment. This complete solution not only provides field monitoring to customers, but also collects all control center data via FineTek MMS (Material Measurement System) Human-Machine Interface, in ZigBee Pro wireless transmission technology. The Rada-style alarm sensor is always the most powerful, reliable and accurate, FineTek likes to face and solve any customer challenges, and provide the best technical solutions for industries.
