Abstract

PURPOSE:To change over from the water cooling roll process to the water hardening process and from the water hardening process to the water cooling roll process with a simple operation without changing the pass line, by installing the water hardening device and water cooling rolls in series so that they may be changed over to each other, and by installing a pickling and neutralizing facility at the outlet side of the furnace. CONSTITUTION:When high tension steel material is manufactured with a continuous annealing facility, heated an soaked strips are quenched at a water hardening device 15 after passing through a primary cooling zone 12, and then, enter into an over aging treatment zone 13. At this time, water cooling rolls 17 of a water cooling roll device 16 have moved upward or downward, and the strip runs through the water cooling roll zone while it is supported only by rolls 17a and 17b at both ends of the water cooling rolls 17. When mild steel material is manufactured, water supply to the water hardening device 15 is stoped, and cooling water is supplied into te water cooling rolls 17. Then, the water cooling rolls 17 are contacted to strips and the cooling is started. The strip then enters into a successive pickling and neutralizing facility 19. When this mechanism is applied, coolings by means of either the water hardening process or the water cooling roll process are freely selected.
