Abstract

Refractory outlet comprises: an opening (1) having an upper and a lower end; an inner wall laterally enclosing the opening; and a heater (2) and/or a thermally insulating material which dissolves or combusts on contact with liquid steel. Preferred Features: The thermally insulating material is cardboard or a material with a melting point lying below the melting point of the steel, or has fibers and is applied by spraying. The heater is made from steel.
