Abstract

PURPOSE: To enhance the effectiveness of productivity and energy by a method wherein waste heat produced in soaking process is used for heating process, and the duct for its waste heat is opened or closed to perform either a single soaking process using a soaking pit or a parallel operation of soaking and heating processes.
CONSTITUTION: Hot steel strip 1A is transferred to a soaking pit 11, heated with many burners 11, the discharged hot steel strip 1A is changed in its fowarding direction by a direction converter 15, is transferred on a roller table 40 and sent to a rolling mill 50. In parallel to the soaking pit 10 is arranged a heating furnace 20 which heats a cold steel strip 1B stored in the material yard. The heat source for the heating furnace 20 uses waste heat from the soaking pit 10, introduced by opening the dumper 31 of the duct 30. The damper 31 is closed when the heating furnace 20 is not used.
