Title: Automatic filling of moulds with molten metal - using ladle providing stream of metal flowing along constant path
Inventor: SATO JIRO
IPC: B22D39/00
Filed: 1977-05-06
Abstract: The vertical cross-section of the ladle has the shape of a segment of a circle. and the free top surface of the metal in the ladle remains constant during tilting and pouring. The ladle is tilted on a horizontal axis near the spout at a speed (V1) until it reaches the pouring position, and is then tilted further at speed (V2), where V1 > V2; the change in speed is continuous, and instantaneous; after pouring, the ladle is returned at a prescribed speed to its original position. During pouring, the stream of metal followed a constant path so there is no need to move the position of the ingate on the mould during pouring. V1 is pref. 40 to 100 times faster than V2, and the change from V1 to pref. occurs in 0.5 seconds. The automatic and rapid filling of moulds where the molten metal stream follows a constant path during the entire pouring cycle; and a magnetic powder clutch and brake can be used to control tilting. The metal is e.g. cast iron poured at 5 kg./second.
