An oxygen blowing lance comprising: a lance body including an oxygen conduit and cooling water inlet and outlet conduits surrounding said oxygen conduit; a lance head connected to said lance body and comprising a nozzle body, said nozzle body including a central strut having bore hole, a plurality of nozzles arranged about said central strut, and a plurality of cooling chambers arranged about said central strut, wherein said plurality of nozzles are in fluid communication with said oxygen conduit for discharging oxygen from said oxygen conduit onto a metal bath in a converter vessel, and wherein said plurality of cooling chambers are in fluid communication with said cooling water inlet and outlet conduits; a temperature probe or camera assembly received in said bore hole for monitoring the temperature of said lance head or molten heat in which the lance is inserted; signal lines connected to said temperature probe for conveying signals from said temperature probe whereby operation of said blowing lance is regulated in response to said signals; and a protective pipe pressurized with a gas disposed in the bore and surrounding said temperature probe assembly and the signal lines.

Metal making lance with spring-loaded thermocouple or camera in lance tip

A stave/brick construction, comprising: a stave having a plurality of ribs and a plurality of channels, wherein a front face of the stave defines a first opening into each of the channels; a plurality of bricks wherein each brick is insertable into one of the plurality of channels via its first opening to a position, upon rotation of the brick, partially disposed in the one channel such that one or more portions of the brick at least partially engage one or more surfaces of the one channel and/or of a first rib of the plurality of ribs whereby the brick is locked against removal from the one channel through its first opening via linear movement without first being rotated; and one or more wear monitors and/or thermocouples, wherein each wear monitor and thermocouple is disposed through or adjacent to the stave and/or one or more of the bricks.
