Heat treatment furnace facilities for the steel industry
HICON roller-hearth furnace for long products.
This type of furnace is designed for normalizing, soft annealing, tempering, and stress relieving of welded and seamless tubes during cold‑drawing operations.
It operates within a processing temperature range of 550 to 950 °C (up to 1,050 °C for specific applications).
The typical net throughput ranges from 2,000 to 12,000 kg/h.
These furnaces are manufactured with a standardized roller useful width (charge width) of 1,800 mm.
Other widths are available upon request.
For certain steel grades requiring an extremely high cooling gradient (up to 300 K/min), the roller-hearth furnace can be equipped with a HICON jet cooler.
The facility can be implemented to comply with the standards required by the automotive industry, in accordance with CQI-9 (AIAG).
