FIELD: metallurgy. ^ SUBSTANCE: device is equipped with removable cover in form of cylinder cartridge with hole in bottom part. A flexible element is made in form of a corrugated disk and is pressure tight connected with an internal side of the case. A moveable element is located inside a cavity formed with the flexible element and the removable cover and has a concave base resting on the flexible element. A stop rod of smaller diametre transfers hold-down force on a contact flange to an electrode passing through the hole in the removable cover. A mechanism of return is positioned around the rod of the moveable element and rests on the bottom section of the removable cover. ^ EFFECT: reduced geometric sizes of device, increased service life and reduced pressure of working substance. ^ 1 dwg |
