    Abstract: A lance for injecting a solid material into a vessel, such as a direct smelting vessel for producing molten iron, has a core tube assembly comprising a passageway for solid material. The core tube assembly has an inlet for receiving solid material at a rear end and an outlet for discharging material at a forward end. The core tube assembly comprises an outer tube of a structural material and an inner tube of a wear resistant material that are bonded together. A method of manufacturing the core tube assembly may include spin casting the outer tube of the structural material; spin casting the inner tube of the wear resistant material onto the inner surface of the outer tube; and metallurgically bonding the tubes together.
