Abstract

The VAI-CON® Link Suspension system has been developed for suspending the converter in the trunnion ring in an ideally, which means statically determined way. The statical determinancy fulfills all the requirements of a modern suspension system: • Allowance of free, unconstrained, unsymmetrical deformation of the vessel shell. No introduction of additional stresses caused by thermal expansion of long-term deformations (creep). • Avoidance of interface gaps between the supporting members. No shock loads and loosening of adjustment and fixation elements should appear during tilting. • With a statically determined system, loads interacting between vessel shell, and trunnion ring can be clearly determined and components subjected to these loads can be properly designed. To meet the aforementioned requirements, the design investigation focused on achieving statical determinacy and unobstructed expansion through the application of the reliable link-element in other suspension systems in a new arrangement.
