Lamination Furnace for Semi-Finished Silicon Steel Strip
Semi-finished electrical steel requires an annealing process with recrystallizing, decarburizing and blueing. The punched laminations are continuously annealed in a roller hearth furnace or for smaller capacity in a pusher type furnace.
LOI Thermprocess, with its over 40 years of experience, has designed and delivered furnaces for heat-treating of silicate and non-silicate semi-processed laminations.
After punching of the semi-processed motor laminations a final annealing is necessary and typically done in a pusher type or roller hearth furnace. The process in both furnaces is recrystallizing, decarburizing and blueing of the semi-processed motor laminations after the punching (stacking).
