A refractory shape is described for transferring molten metal in a continuous casting operation. The shape includes an inner surface made from an unfired composition comprising a calcium rich grain, a hydration-resistant grain, 6-28 wt. % carbon, and a binder. The unfired composition may also include an antioxidant and silica. The inner surface resists spalling and alumina deposition. |
