ABSTRACT:
A melting vessel plant, in which the melting vessel is a converter vessel, to which a vessel cover with a pipe connection for removing the flue gases is attached. Either an oxygen lance with an auxiliary cover or electrodes with an auxiliary cover are introduced into the melting vessel through the vessel cover. The spherical melting vessel is lined with a lining. It is arranged on running rails as a traveling melting vessel, and it is mounted on an inner running rim and an outer running rim. The melting vessel is fastened to the inner running rim by support elements arranged on the circumference. Both running rims are interlocked by shear wedges. With the melting vessel locked, a cable winch with traction cables makes possible the tilting movements of the melting vessel both in the direction of steel tapping on the running rails and back into the upright position.
