FIELD: heating.
SUBSTANCE: invention relates to equipment for sintering powder items, diffusion welding of composite items in vacuum, in a gas medium with low excess pressure and the high pressure of gases up to 10 MPa and the temperature up to 2,500 °C. In the proposed vacuum-compression furnace on the movable plug beside the table there are: a heat-insulating cap, current leads with heaters and inspection windows for pyrometers measuring the product temperature at high heating temperatures in addition to thermocouples. Besides, the vacuum-compression furnace is equipped with high-pressure seals and in-series located vacuum seals behind them arranged at points of the housing connection with plugs, a gate with a plug, current leads and inspection windows with a movable plug, herewith the heat-insulating cap at compression processing is equipped with tightly arranged transparent lenses, to which from the heating working zone tubes are brought to supply the gas and create a gas curtain in front of the cap inspection lenses.
EFFECT: easier furnace maintenance, higher reliability of its operation are provided.
