[origin: US4523627A] PCT No. PCT/FR82/00115 Sec. 371 Date Mar. 7, 1983 Sec. 102(e) Date Mar. 7, 1983 PCT Filed Jul. 7, 1982 PCT Pub. No. WO83/00107 PCT Pub. Date Jan. 20, 1983.The present invention concerns a process for vertical continuous casting at speeds which are close to a meter per minute. The process is characterized in that the use of a top feeder head and an electromagnetic field are combined and that, by controlling the position in respect of height of the top feeder head and the cooling system relative to the field generating means, the distances between certain parameters such as the solidification front and the base plane of the top feeder head are maintained constant in the course of the casting operation. This process makes it possible to cast aluminium and alloys thereof in the form of billets or plates, the smallest dimension of which does not exceed 150 mm and which have a surface that does not require any scalping treatment.
