review text: An analysis of the flow of a rigid-viscoplastic Bingham solid through an annular orifice with streamline profile is given. The problem was suggested by the hot extrusion of tubes when melted glass is used as lubricant. A kinematic velocity field is obtained for this problem by minimisation of the functional attached to this problem. The ram pressure, the melted glass zone, etc. are numerically determined for this velocity field. Some numerical examples are given for various working speeds.
