摘要： PROBLEM TO BE SOLVED: To provide a heat treatment method for thick steel plate which can obtain material characteristics less in variation and enhances productivity. SOLUTION: In the heat treatment method using a direct fired roller-hearth type continuous heat treatment furnace or a radiant-tube roller-hearth type continuous heat treatment furnace, the heat treatment is applied to a plane steel thick plate in the heat treatment temperature range of 300-450°C. In the heat treatment temperature range, the aimed heat treatment temperature range of Ts min to Ts max (°C) is set based on the temperature fluctuation range permissible in the material quality. As for this aimed heat treatment temperature range, the setting temperature range in the continuous heat treatment furnace is regurated so that the lower-limit temperature TG min (°C) is defined as the upper-limit temperature +10°C or higher in the aimed heat treatment temperature range, and the upper-limit temperature TG max (°C) is defined as Ts min to Ts max (°C) in the aimed heat treatment temperature range, and is lower than the temperature preset by specific formula according to the plate thickness (t)mm of the thick steel plate, and thus, the heat treatment is perfoermed by setting the furnace temperature TG (°C) in the continuous heat treatment furnace within this setting temperature range.

摘要： PROBLEM TO BE SOLVED: To calculate a stray light noise caused by a furnace wall by a simplest possible method without lowering accuracy as much as possible. SOLUTION: A radiation thermometer 100 is installed on a position facing to the surface of slab 21 from above a heating zone 13, and thermocouples 200 are scattered on a ceiling surface 13a of the heating zone 13. A temperature measuring object domain 210 determined based on installation positions of the thermocouples 200 and zones A-L determined by dividing the temperature measuring object domain 210 are defined. A stray light noise brightness is determined in each zone by using each temperature of the thermocouples 200, and a value determined by adding each determined stray light noise brightness in each zone is used as the stray light noise brightness of the whole zone. On the other hand, as for a domain on the ceiling surface 13a other than the zones, each stray light noise brightness is determined as a whole by using properly calculated temperatures. Then, a self-emission brightness emitted from the slab 21 itself is determined by subtracting the determined stray light noise brightness from the emission brightness acquired by the radiation thermometer 100.
