Abstract
The invention relates to a tilting mechanism for a tilting metallurgical vessel, in particular a converter, around a horizontal axis, comprising a rotatable shaft and at least one tilting drive mechanism for rotating the vessel about the axis, the at least one tilting drive mechanism has a fixed part and a moving part, wherein the moving part of the at least one tilting drive mechanism is directly connected to one end of the rotatable shaft.
Claims14
A tilting mechanism for a metallurgical vessel, comprising:
- a trunnion ring defining a horizontal plane, wherein the metallurgical vessel is disposed in the trunnion ring such that a center of mass of the metallurgical vessel is below the horizontal plane;
- first and second trunnions connected to the trunnion ring defining a horizontal axis;
- first and second fixed supports adapted to provide support between the first and second trunnions and a fundament;
- a first tilting drive mechanism connected to the first trunnion to tilt the metallurgical vessel, wherein the first tilting drive mechanism comprises
- a moving part connected to the first trunnion,
- a fixed part fixedly connected between the moving part and the fundament without gears,
- an adjustable hydraulic pump, and
- a flow control unit connected between the adjustable hydraulic pump and the moving part.

A method of reducing vibrations during blowing in a converter, comprising:
- providing a converter assembly comprising a converter and a tilting mechanism for the converter, wherein the tilting mechanism comprises a trunnion ring defining a horizontal plane, wherein the converter is disposed in the trunnion ring such that a center of mass of the metallurgical vessel is below the horizontal plane, first and second trunnions connected to the trunnion ring defining a horizontal axis, first and second fixed supports adapted to provide support between the first and second trunnions and a fundament, a first tilting drive mechanism connected to the first trunnion to tilt the metallurgical vessel, wherein the first tilting drive mechanism comprises a moving part connected to the first trunnion, a fixed part fixedly connected between the moving part and the fundament without gears, an adjustable hydraulic pump, and a flow control unit connected between the adjustable hydraulic pump and the moving part;
- a shut-off valve interposed between the adjustable hydraulic pump and the flow control unit;
- positioning the converter in a blow position without locking the converter;
- and
- allowing the converter to swing around the fixed, horizontal axis during oxygen blowing, thereby reducing vibrations.
