Fluid cooled housing system for instruments of a metal making furnace

A fluid cooled housing system for use in a metal making furnace, the fluid cooled housing system comprising:

• a housing comprising:
• a substantially cylindrical outer shell defining a void and having a first end, a second end, a diameter, and a longitudinal surface comprising a length that extends from the first end to the second end;
• a substantially cylindrical inner shell defining a void and having a first end, a second end, a diameter and a longitudinal surface comprising a length that extends from the first end to the second end;
• a fluid chamber through which a cooling fluid may flow;
• a baffle tube;
• an end cap comprising a cooling system;
• a face plate;
• a bushing insert comprising a cooling system;
• a fluid inlet and a fluid outlet;
• wherein the diameter of the outer shell is greater than the diameter of the inner shell, wherein the inner shell is nested within the void of the outer shell and connected to the outer shell such that the longitudinal surface of the outer shell is adjacent and substantially parallel to the longitudinal surface of the inner shell along approximately the entire respective lengths of the respective longitudinal surfaces, and wherein the longitudinal surface of the outer shell and the longitudinal surface of the inner shell define the fluid chamber having a first end and a second end;
• wherein the baffle tube is located within the fluid chamber, the fluid chamber thereby being partitioned by the baffle tube;
• wherein the end cap is connected to the first end of the outer shell and the first end of the inner shell such that the first end of the fluid chamber is closed off by the end cap;
• wherein the face plate is connected to the second end of the outer shell and second end of the inner shell via a sealing member such that the second end of the fluid chamber is closed off by the face plate;
• wherein the bushing insert is both installed in the void defined by the inner shell and attached to the end cap;
• and
• wherein the fluid inlet is in fluid communication with both of the fluid chamber and the cooling system of the end cap, and wherein the fluid outlet is in fluid communication with both of the fluid chamber and the cooling system of the end cap.
