摘要： A method for operating a rotary machine with a rotor that is mounted in a bearing is provided. The rotor is subjected to a thrust that acts substantially in only an axial direction during the operating time. The thrust is received and dissipated by a first thrust bearing of the bearing via sliding means, the bearing having a second thrust bearing. The axial vibrations of the rotor are damped or completely prevented by means of the second thrust bearing generating a force that acts on the first thrust bearing in the direction of the thrust at least temporarily at the same time as the thrust occurs.

摘要： Thick-walled parts made by means of a casting method often exhibit, in those thick zones, the worst mechanical properties since the solidification speed in said zones is reduced relative to the thin-walled zone and frequently induces the worst mechanical properties. There is described a method incorporating control elements in a melting charge, said elements increase locally the solidification speed of the melting charge.
