- Converter 2 by means of such blades 7 on the support ring 3 is in the prior art, for. B. from WO 2011/064233 A2 and therefore not further explained in detail.
- the fastening system 1 comprises retaining means 8, which are attached to an outer side of the converter 2. These holding means cooperate with guide means 9 in the form of an oblong hole, which is formed on an underside of the support ring 3.
- the fastening system 1 comprises the support ring 3, the holding means 8 and the
- the holding means 8 comprise a load bolt 10, which is attached to an outer console 11 attached to the wall of the converter 2.
- the load pin 10 extends with its longitudinal axis, starting from a base 12 of the outer panel 11 vertically upward.
- the load pin 10 may be attached to the outer console 1 1 by a screw 13, which is symbolically indicated in Fig. 2. If necessary, thus the load pin 10 can be replaced by the outer console 11.
- the slot 9 is formed in a lower flange 14 of the box-shaped support ring 3.
- the load pin 10 engages in the slot 9 in such a way that it along the longitudinal axis of the slot 9 or along an axis (y), the radially in the direction of
- Fig. 3 is a sectional view taken along the line B-B of Fig. 2.
- the load pin 10 laterally in each case in contact with the
- Load bolt 10 and the longitudinal side edges 15 of the slot 9 is designed with respect to the fit and the material pairings to the effect that the load pin 10 is guided on the one hand in a direction (x) transverse to the longitudinal axis of the slot 9 play, and on the other hand, a mobility of the load bolt 10 both in
- tilting forces which act on the converter 2. These tilting forces occur with reference to FIG. 1 in the direction of the x-axis.

- recesses 27 may be formed, in which the sliding plates 18 are added. Through the side walls of the recess 27 advantageously the transverse forces are absorbed, which in a
- FIG. 5 illustrates that the longitudinal side edges 15 of the slot 9 are formed by the vertical side surfaces 20 of the respective wedge elements 19.
- a width b of the elongated hole 9 or a distance of the vertical side surfaces 20 relative to one another can be set by introducing a spacer body 28 having a predetermined thickness between the lower bottom surface 24 of a wedge element 19 and the support surface of the base section 25.
