COMBINED FORGED AND CAST LANCE TIP ASSEMBLY

摘要

A lance tip assembly for a water-cooled lance as well as a method for constructing same. The lance tip assembly includes a first component (10) of solid cast metal which is secured to a second or lower component (26) of forged metal. Each active material discharge nozzle (22) of the combined forged and cast lance tip assembly is constructed in part of the first cast component (10) and the second forged component (26). Only a single bond (50) is required to join the first (10) and second (26) component at each nozzle site (22). The first (10) and second (26) components are fabricated to include structural features which individually and collectively promote high coolant water flow velocity through the lance tip and substantially uniform cooling of the face (25) of the lance tip.
