Synopsis : A new annealing pickling line has been put on stream at Chiba Works in October 1982. Meeting with the demands of the age, this large-scale line efficiently produces coils of large dimensions, i.e., maximum 8 mm thick and 1 600 mm wide, available from various kinds of stainless steel and high carbon special steel. In this construction careful consideration was given to the thoroughgoing protection of environment. Especially a new method to regenerate HNO3 and HF efficiently was successfully developed by introducing Fe-removing process. This development was commissioned to Kawasaki Steel by Research Development Corporation of Japan (J.R.D.C). This AP line and its auxiliary acid recovery plant, to which the above-mentioned new systems have been introduced, are now in smooth operation. |
