Abstract: The thermostatically controllable tank container has a support structure with the dimensions of a parallelepipedic, standardized container. In the support structure (1) is provided a circular cylindrical tank (3) with a non-supporting thermal insulation jacket (4). Between the tank skin and the thermal insulation jacket are provided longitudinally directed ducts (9) for carrying a heating or cooling medium. The external diameter of the tank is essentially adapted to the internal dimensions of the square cross-section of the support structure, so that there is an optimum utilization by the cylinder of the theoretically available space of the parallepiped. The thermal insulation jacket adapted to the tank contour is arranged within the parallelepiped shape defined by the support structure (1).

Abstract: Apparatus and method are disclosed for monitoring the condition of a basic oxygen furnace (BOF) trunnion bearing. A shaft attached to a basic oxygen furnace (BOF) vessel is supported on either vessel side by a radial bearing which allows rotation of the shaft with respect to those bearings. One of the radial bearings is in turn mounted to a ladder bearing which allows shaft expansion and contraction with temperature. A Hall Effect transducer is mounted on both bearing sides to monitor the distance between the shaft and the transducer. If an output from the transducer deviates from a predetermined range the shaft position has shifted. This shift is an indication that either the radial or ladder bearing has or may in the near future fail. The apparatus therefore provides a warning that either replacement or repair of the BOF vessel trunnion bearing may be required.
