Cold Rolling - Continuous Annealing Furnace
A continuous annealing furnace makes it possible to integrate the conventional batch annealing process (i.e., electrolytic cleaning - annealing - cooling - temper rolling - recoiling) into one line. The use of such a furnace can lead to significant energy saving and productivity. For instance, for a particular continuous annealing furnace in Japan, the annealing time for one roll is approximately 30 minutes, as compared to approximately 10 days for the conventional bath process. The installation of continuous annealing equipment demands relatively high investment costs (US EPA, 2010. p. 30).
