Abstract (en)
[origin: EP3686298A1] A fixed type thermal coil heat insulation heat treatment device, comprising: a steel coil tray (1); at least one steel coil bearing support (2), which is disposed on the steel coil tray; and a thermal insulation cover (3), covering the steel coil bearing support, the inner cavity volume of the thermal insulation cover being larger than the total volume of at least one steel coil (100) and the steel coil bearing support. The lower end of the thermal insulation cover is movably connected to the steel coil tray. According to the fixed type hot coil thermal insulation heat treatment device, after coiling is completed, a steel coil is immediately subjected to thermal insulation treatment, the intermediate transfer time is reduced, and heat of the steel coil itself is used for performing 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.
