The Basic Oxygen Furnace comprises a tiltable vessel supported by two trunnions in large roller bearings. To accommodate thermal expansion, the floating bearing is mounted on a deep curved beam which moves axially on two linear bearings. Under loads of 1 to 2 million pounds, the elastic deflection of this beam alters the static load capacity of the roller bearing. This paper describes a computer assisted analysis based on Castigliano’s First Theorem for determining the effective bearing capacity, and secondly for optimizing the beam design.
