Molybdenum wire molybdenum block sintering furnace working process，The workpiece is mounted on the workbench, and after the material is raised, the lower furnace mouth is sealed. Close all intake and exhaust valves, start the vacuum pump, pump the furnace to 10Pa, stop the vacuum pump, open the hydrogen filling valve, and when it is charged to 1.02atm, open the hydrogen exhaust valve. After the alarm starts, the exhaust pressure is automatically adjusted to 1.0003~ 1.0008atm continuously removes hydrogen and then passes hydrogen, and sinters according to the heating curve. After the completion of the power failure, when the furnace temperature drops to 200 °C, close the intake and exhaust valves, open the vacuum pump, and pump to 10Pa, open the bleed valve to fill the furnace with air to normal pressure, reduce material, discharge, reload Material for the next sintering cycle
