Abstract
A two-piece tundish nozzle assembly block is provided for the drain regions of tundish vessels. The two-piece assembly block includes a lower main block firmly mounted in the refractory lining of the tundish, and a selectively removable top sleeve which, together with the refractory lining, protects the lower main block from direct exposure to molten iron or steel. The top sleeve is directly exposed to molten iron or steel passing into the drain. The top sleeve is not strongly bonded in place, and can be easily removed and replaced when worn or damaged.
