This invention refers to a pouring cylinder including a bucket (2) and a metal band (3) coaxially placed, and two bridge-boards (5, 6) for metal band supporting and radial centering upon bucket. Each bridge-board includes a blurred-conical part (51, 61) which cooperates with a corresponding blurred-conical surface (34, 35), of metal band holes or drill, such blurred-conical surface being located in a zone where metal band internal diameter variations, due to dilatation deformations, are sensibly null. Application is mainly for continuos pouring between steel thin product cylinders.
