Abstract
1. Сопло дугового плазмотрона, содержащее металлический корпус с кольцевой полостью для охлаждения сопла и термостойкую коническую втулку с каналом для выхода плазмы, которая закреплена в коническом гнезде, выполненном в корпусе сопла соосно с кольцевой полостью, отличающееся тем, что коническая втулка выполнена из материала, имеющего коэффициент теплового расширения по величине меньше, чем коэффициент теплового расширения металла, из которого выполнен корпус сопла, при этом коническая втулка выступает из конического гнезда в корпусе с возможностью последующего углубления ее в гнездо при нагревании в процессе диффузионной сварки втулки с корпусом. ! 2. Сопло дугового плазмотрона по п.1, отличающееся тем, что конусность посадки втулки в гнездо корпуса составляет от 1:50 до 1:200. ! 3. Сопло дугового плазмотрона по пп.1 и 2, отличающееся тем, что корпус сопла выполнен из меди, а коническая втулка выполнена из молибдена.1. The nozzle of the arc plasma torch, comprising a metal casing with an annular cavity for cooling the nozzle and a heat-resistant conical sleeve with a channel for plasma exit, which is fixed in a conical socket made in the nozzle body coaxially with the annular cavity, characterized in that the conical sleeve is made of material, having a coefficient of thermal expansion in magnitude smaller than the coefficient of thermal expansion of the metal of which the nozzle body is made, while the conical sleeve protrudes from the conical socket in the body the possibility of further deepening it in the slot when heated in the process of diffusion welding sleeves to the body. ! 2. The nozzle of the arc plasma torch according to claim 1, characterized in that the taper of the fit of the sleeve into the housing socket is from 1:50 to 1: 200. ! 3. The nozzle of the arc plasma torch according to claims 1 and 2, characterized in that the nozzle body is made of copper, and the conical sleeve is made of molybdenum.
