The short answer
InduQT helps smaller steel plants and foundries catch failures early on the equipment that stops production: induction-furnace cooling water, mill motors and gearboxes, hydraulic systems and cranes. You start with off-the-shelf sensors (current clamps, temperature probes, flow switches, vibration sensors) or the data your PLCs already hold, and InduQT learns each machine’s normal and warns before limits are reached, with the likely cause from the manual and your own history.
Who it is for
- Re-rolling mills (TMT bar, wire rod, sections)
- Induction-furnace foundries and melt shops
- Pipe, tube and wire mills
- Galvanising and fabrication shops
- Maintenance teams of mid-size integrated plants who want to start small
What it solves
A cooling problem on the furnace stops everything
Scaling coils, blocked hoses and weak pumps show up first as a rising water temperature rise across the coil. Two clamp-on probes and a flow switch catch the trend weeks before the trip.
Mill drives and gearboxes fail without warning
Motor current, bearing temperature and overall vibration, compared with each machine’s own normal and with its sister stands, give the early warning that a breakdown does not.
Logs live on paper and in Excel
Shift logs of temperatures and pressures are valuable history. Upload them and InduQT learns from the past before the first sensor arrives.
Where to start
Each guide lists the sensor to buy, how to turn on MQTT, how to check the readings with Claude or ChatGPT, and how to wire them to InduQT.

Already collecting data?
- Furnace and mill PLCs with Modbus or OPC UA: read them without changing the program.
- Shift log sheets and Excel: upload months of history.
- Home-grown SCADA or a database: we connect it for you with an annual plan.
What to know first
- Monitoring only: InduQT never replaces furnace cooling interlocks, crane safety systems or mill protections, and the sensors in our guides are kept separate from them.
- Electromagnetic noise near induction coils and large drives can upset Wi-Fi: keep sensors away from the coil and use Ethernet where possible.

Frequently asked questions
Can InduQT read our furnace controller?
If it has Modbus, OPC UA or an export, yes. If not, two probes on the cooling water and a flow switch give the most important signals without touching it.
Does this work for large integrated plants?
InduQT is built for plants without a data team. Large plants often use it for areas the central system does not cover, or start with one line.
