  • Batch-Annealing an overview ScienceDirect Topics

    Strand annealing has been used in the tinplate industry for the annealing of thin strip 4 and other similar research programs were evident in the UK in the 1960s. However, continuous annealing process line (CAPL) technology (see Figure 3.2 (b)) was only introduced for the processing of automotive sheet, as an alternative to batch annealing, in the last 15 years.

  • WorldOfSteel Continuous Annealing and Batch Annealing

    In batch annealing, tightly wound coils of cold rolled steel are stacked three or four high on bases with convector spacers between coils. A cover is lowered onto the stack and is sealed at the base. The atmosphere surrounding the coils is purged and replaced with slightly reducing atmosphere. A movable furnace is placed over the entire charge

  • Comparison between Conventional Annealing and Rapid

    Conventional annealing (CA) of low-carbon (C 0.10) steels in batch-annealing furnace using slow heating rate (10°C/s) and prolonged holding (> 1 hr.) at a temperature (600-700°C) below A c1 offers yield strength (YS) of 200-300 MPa[1].
