Abstract (en)

A water cooled box to be installed in the side wall of a metal making furnace to hold and protect implements such as a burner, a lance, or a material (i.e., carbon or lime) injection device. The box preferably comprises a copper outer shell and a steel inner shell liner welded together, whereby a chamber is formed through which cooling water passes. The box further comprises an inlet and outlet for the water flow and a plurality of conduit passages between the copper and steel shells for mounting the aforementioned implements. The copper shell has bars or slots for slag retention and the steel shell has means for mounting the box into the furnace wall. The copper shell is formed into a curved U-shape for preventing cracking due to thermal mechanical stress and to raise the natural frequency of the panel to resist vibration which can also cause cracking.
