GAS-STATIC EXTRUDER Russian patent published in 2011 - IPC B22F3/15 B30B15/34 

FIELD: machine building.

SUBSTANCE: invention refers to equipment for treatment of items for industrial use out of discrete and solid materials at simultaneous or combined effect of high - to 500 MPa - pressure and temperature to 2000°C. The gas-static extruder consists of a power bed plate and container closed on ends, with upper and lower plugs, with a working chamber, connected with gas system of gas-static extruder, and with a heat insulating hood and heater arranged in it. Also, the gas-static extruder is equipped with a system of accelerated cooling installed in the heat insulating hood and elements of the heater system. The system is made in form of gas lines connected to an upper section of the working chamber of the container. The gas-static extruder is equipped with an ejector. It is also equipped with an additional cavity in the container, while the ejector is positioned in a lower cylinder part of the heat insulating hood and is made along whole perimetre of a lower part of the additional cavity of cooling.

EFFECT: facilitating motion of gas with sufficient high speed regardless to considerable resistance, also, facilitation of uniform accelerated cooling of work-pieces.
