FIELD: process engineering.
SUBSTANCE: claimed invention relates to liquid-cooled plasma torch nozzle. Said nozzle comprises nozzle nose tip bore for release said plasma jet. Nozzle nose tip outer surface is, in fact, a cylindrical surface. It has second section abutting on first section on nozzle nose tip side. Its outer surface converges toward nozzle nose tip to, in fact, the cone. Note here that there at least one fluid feed groove extending partially over the first section and over the second section at nozzle outer surface towards nozzle nose tip. Besides there is one fluid discharge groove separate from fluid feed groove extending over the second section. Note here that there at least one fluid feed groove extending partially over the first section and over the second section at nozzle outer surface towards nozzle nose tip. Besides there is one coolant discharge groove separate from fluid feed groove extending over the second section.
EFFECT: efficient cooling of nozzle nose tip, ruled out its thermal overload.
