Smarter temperature control of multi-stage seam annealing stations

SPC also enables annealers to engage automatically with the mill run signal. Offering manual or fully automated temperature control, both minimum and maximum annealing temperatures can be set between 300°C and 1300°C. Process parameters are stored for each product. Selected process variables are logged during each run for API documentation purposes, and the system is fully automated.

annealing stations. With Smart Anneal, API pipe producers can quickly and accurately position adjacent annealer carriages by accessing stored

database parameters for a given set of pipe diameters. The result is faster, easier operation that delivers the additional benefits of superior, repeatable heat treatment plus a reduction in scrap. At the heart of the system is selectable speed power control (SPC) whereby real time feedback via the PLC will automatically adjust the output power at each annealing heat station, taking into account mill speed.
