PROCESS AND APPARATUS FOR DELIVERING A METERED SHOT |
摘要 |
An apparatus for delivering a metered shot of molten metal from a dispensing vessel through a shot tube comprises: a dispensing vessel for holding molten metal and having a shot tube for discharge of the molten metal, a reservoir of gas for pressurizing the dispensing vessel, a variable regulator for regulating the flow of gas. The regulator has a backload for varying the pressure at which the regulator regulates the flow of gas. An exhaust vent vents the dispensing vessel to the atmosphere. A supply valves opens and closes the delivery of gas to the holding vessel. A controller (i) maintains the exhaust valve closed, opens the backload and the supply valve pressurizing the holding vessel until the molten metal is at a predetermined level in the shot tube, (ii) closes the backload fixing the delivery pressure and maintains the delivery pressure within the holding vessel for a predetermined period of time discharging molten metal out the shot tube, (iii) closes the supply valve and opening the exhaust vent terminating the discharge of the molten metal.
