Abstract (en)
[origin: EP3686297A1] A movable hot rolling thermal insulation heat treatment device, comprising: a base plate (1); a steel coil fixing base (2), disposed at the center on the base plate (1); a tray (3), which is of an annular structure and is horizontally fitted at the middle part of the steel coil fixing base (2); a thermal insulation cover (4), having an opening at the lower end and covering the tray (3), the inner cavity volume of the thermal insulation cover (4) being larger than the volume of a steel coil; an electric heating device (5) disposed on the inner side wall of the thermal insulation cover (4); a temperature sensor (6) disposed in the thermal insulation cover (4); and an information acquisition control module (7) electrically connected to the electric heating device (5) and the temperature sensor (6). The device can utilize the heat of a steel coil itself to perform a soaking and slow cooling heat treatment process on the steel coil, thereby achieving the purposes of high efficiency, energy conservation, and improvement of the yield.
