<p>A refractory pouring-assembly component is disclosed for use in the continuous casting of molten metals, especially steel. The invention is described as reducing thermal shock-induced cracking, including both radial and horizontal cracks. The component comprises a copressed plate (22) and depending pour tube (23) having a bore (2). The surface of the plate is made from a scratch-resistant refractory material and the pour tube is made from a thermal shock-resistant refractory material. The pour tube extends through and is substantially coplanar with the plate, so that the molten metal sees a joint-free, thermal shock-resistant material throughout the entire length of the bore.</p> |
