Abstract
A flow starting tube for initiating the discharge flow of molten material in a vessel through a bottom discharge opening thereof extends upwardly from a lower end fitted to the discharge opening to thereby block access of the molten material to the discharge opening. The flow starting tube has a configuration such that it is broken away at a predetermined breaking position when the level of molten material in the vessel reaches a suitable level. Such breaking away at the predetermined breaking position is achieved under the influence of the molten material burning through the flow starting tube at the predetermined breaking position and/or the influence of the buoyancy in the molten material of a portion of the flow starting tube above the predetermined breaking position.
