Nozzle to provide fan-shaped spray pattern

摘要

An improved spray nozzle assembly particularly adopted for use in continuous casting apparatus and the like utilizing an atomized mixture of pressurized water and air as the cooling medium. The nozzle assembly is adapted to be interposed between the rolls of the casting apparatus and to deliver a cooling spray in the form of a fine mist distributed uniformly over a predetermined area of the ingot or slab. The assembly includes a specially formed mixing nozzle and discharging nozzle tip having turbulence generating shoulders, a transverse mixing chamber, and specially formed discharge orifice controlling the shape of the spray pattern and the uniformity of coolant distribution within that pattern.
