Abstract: A mechanical probe apparatus for taking measurements with a sensor cartridge inside a metallurgical furnace. The apparatus has a housing, and a mounting member to receive the sensor cartridge, the mounting member being movable from being withdrawn in the housing to extending outside of the housing. The housing, itself, is movable from being exterior of the furnace to a position wherein a portion of the housing extends into the furnace through a portal. The sensor cartridge can be mounted to the mounting member when the housing is exterior of the furnace and the mounting member extends outside of the housing. The sensor cartridge can then be withdrawn into the housing on the mounting member and the housing can subsequently be moved into the furnace. Thereafter the sensor can be extended outside of the housing to take measurements when the housing is within the furnace.

Abstract: A remotely controlled, semi-automatic sampling and temperature measuring apparatus for steelmaking comprises (i) an air-cooled main probe body carrying a retractable metallic pipe pole containing a plurality of measuring cardboard cartridges by means of a push-pull driving mechanism; (ii) a non-cooled half-moon circular probe housing comprising a rotating arm for inserting and removal of the main probe body from the furnace by means of a hydraulic rotating actuator; and (iii) a double sided frame arm connected to the furnace shell for rotating and repositioning the half-moon circular probe housing and the main probe body away from the furnace for replacing the cardboard cartridges.

Abstract: A sealing apparatus for a slag door of a metallurgical furnace, having a mounting assembly for mounting the apparatus to the furnace, and at least one closure element, moveable from an open position that is exterior of the slag door opening, to a closed position that effectively seals against the slag door and extends into the slag door opening with the rear panel of the closure element(s) being proximally aligned with the interior wall of the furnace. The apparatus may also have at least one wiping component moveable so as to sweep across the lower surface of the slag door to remove obstructions.
