Extended blast furnace shutdowns introduce risk should the salamander completely freeze during the stop. This risk was identified by an operator when planning a 10-day shutdown of a blast furnace to replace copper staves. To mitigate this risk, Hatch and the operator assessed the extent of salamander freezing using transient heat transfer analysis. The salamander freezing time was estimated for several scenarios and strategies to safely delay freezing were identified. Hearth temperatures were monitored from blowdown to blow-in and compared to estimates, details of which will be presented herein.
