Abstract

836,260. Degassing molten metals. DORTMUND-HORDER HUTTENUNION A. G. Nov. 15, 1957 [Nov. 29, 1956; Dec. 18, 1956], No. 35688/57. Class 72 A method of agitating a metal melt comprises repeatedly withdrawing a portion of the melt into a vessel disposed above the melt and at sub-atmospheric pressure and then rapidly increasing the distance between the vessel and the melt so that the portion is returned to the melt with high energy and the melt vigorously agitated. As shown, metal is withdrawn from a furnace 2 into a vacuum vessel. 4 so that its surface B is at a distance h from the surface of the melt L. The vessel 4 is then moved rapidly upwards, e.g. by hydraulic means, so that most of the metal in the vessel is returned to the melt. The pipe 3 through which the metal flows may be curved and the bottom of the furnace may also be shaped to increase the agitation. Specification 801,518 is referred to.
