We are seeking high-temperature visual inspection solutions to detect refractory damage, cracks and material build-up inside blast furnace blowstock and bustle main during shutdowns at temperatures of ~800-1000°C.

Taphole drill alignment is currently verified manually near the blast furnace front, exposing operators to high temperatures and relying heavily on operator judgement. We seek an automated solution to identify the taphole centre, verify drill tool orientation and seating, and provide real-time alignment feedback, improving safety, drilling consistency, and operational reliability.
