Production of a directed spray by atomising molten metal.

摘要

For uniformly coating a substrate 30 with a spray, a stream 1 of liquid falls past a point towards which five nozzles 21 in a bank 20 are all directed but at different angles. The bank 20 and a second bank 20 (not shown) flankthe stream 1. Bursts of atomising gas are fired through the respective nozzles in a repeated sequence, such as to cause a repeated sequence of five equal durations of spray in the five directions (shown in dotted lines) in turn.
