Method for producing a high pressure nozzle

摘要

#CMT# #/CMT# The nozzle (10) has a feed channel with a beam directing device (26) formed with a discharge opening (22). A neck of the feed channel is provided downstream to the beam directing device. The beam directing device comprises a free flow section in a proximate region that encloses a center longitudinal axis (30) of the feed channel. The nozzle fastens a section with constant width at the neck of feed channel, where the section is crossed over a tapered discharge chamber. The section includes length that is twice the length of the neck of the feed channel. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a high pressure nozzle. #CMT#USE : #/CMT# High pressure nozzle for scaling steel products. #CMT#ADVANTAGE : #/CMT# The section of nozzle with constant width includes length twice the length of neck of the feed channel, thus making the ratio of free flow section surface at the beam directing device to the free flow section surface of the filter to be more larger or 1:6. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective sectional cut-away of a high pressure nozzle. 10 : High pressure nozzle 22 : Discharge opening 24 : Filter 26 : Beam directing device 30 : Center longitudinal axis.
