Abstract
Ingress of gas such as air through the joint of a pour tube and tube holder of a continuous caster is prevented or inhibited by passing an inert gas into a circumferential channel around the orifice and at the interface of the joint; the gas is evenly distributed within the channel over the entire configuration of a porous refractory insert in the circumferential channel; the porous refractory insert assures even distribution of the gas to the desired location in the joint.
