A converter is provided having a converter vessel carried on a trunnion ring by a mounting system. The mounting system has six mounting elements including a plurality of mounting elements incorporating pendulum rods and one mounting element incorporating a stabilizer device. Each pendulum rod is connected at one end to the trunnion ring and at the other end to the converter vessel. In a preferred embodiment of the invention, the mounting system includes three longitudinal mounting devices each having a longitudinal pendulum rod; two transverse mounting devices each having a transverse pendulum rod; and a stabilizer device having a pair of spaced stabilizer blocks connected to the trunnion ring and a pair of stabilizer elements connected to the converter vessel. The longitudinal mounting devices and the stabilizer device are located below the trunnion ring and the transverse mounting devices are located above the trunnion ring when the converter vessel is in an upright position. A statically determinate mounting of the converter vessel in the trunnion ring is thus accomplished with six mounting elements including five pendulum rods and one stabilizer device.

Tiltable converter

In a method of cooling a hot surface, a liquid cooling medium is atomized by a plurality of nozzles in a hollow space surrounding the surface and open towards the atmosphere. In order to ensure uniform continuous, yet just sufficient, cooling of the hot surface, with the cooling effecting with a constant temperature as possible over an extended period of time while avoiding changing thermal expansions of the hot surface, the liquid cooling medium is continuously atomized by means of unary nozzles to a fine mist having a droplet size ranging between 4 and 60 .mu.m. The mist leaves the unary nozzles at a low speed and is moved along the hot surface within the hollow space surrounding the hot surface under utilization of the natural thermal current in the hollow space.

Method of cooling a hot surface and an arrangement for carrying out the

A tiltable converter arrangement is disclosed in which a converter vessel is supported by a carrying ring surrounding and spaced from the converter. The carrying ring includes two diametrically oppositely arranged carrying trunnions. The converter is supported within the carrying ring by a plurality of guide rods, the converter being movable in the upright position. Each of the guide rods is designed as a pendulum rod each have a first end and a second end in which the first end is connected to the carrying ring by means of a spherical bearing and the second end connected to the converter vessel also by means of a spherical bearing, such as to provide an articulate universal joint between the carrying ring and the converter vessel.
