Abstract
An equipment line for manufacturing heavy-walled steel products having excellent low-temperature toughness, the equipment line including a heating device, a cooling device, and a hot working device in this order. The working device includes plurality of hot working devices, and the cooling device is arranged on an entrance side of at least one of the plurality of hot working devices. Furthermore, a thermostat equipment is arranged on an exit side of the hot working device. The equipment line provides a steel product with a finer microstructure with a relatively small amount of working.
