Patent GB-351524-A (GB)
Title: Method of producing aluminium and aluminium alloys
IPC: C22B21/00
Filed: 1930-03-24
Abstract: Aluminium and aluminium alloys are produced by the electrothermic reduction of aluminium oxide-containing substances in the presence of substances, such as iron and silicon, that reduce the vapour pressure of the aluminium, so as to form a crude alloy which is afterwards separated into an alloy rich in aluminium and one poor in aluminium by known processes such as liquation, centrifugation and cooling.  To obtain aluminium the rich alloy is distilled with the aid of a vacuum.  If iron is used the crude alloy must contain at least 70 per cent of aluminium, but in the case of silicon the aluminium content may be less.  The temperature of separation of the crude alloy should be maintained as near as possible to the eutectic temperature of the rich alloy.  In the reduction of clay and kaolin sufficient carbon is added for reducing purposes and the crude alloy is transferred in liquid condition to a liquation furnace and kept at about 600 DEG  C. Silicon needles crystallize out and iron sinks to the bottom as a silicon-containing iron aluminium compound together with all the titanium as Al4Ti.  The top and bottom mixtures are treated by pressing or the like and the rich alloy produced in both cases contains about 12 per cent of silicon with some iron and titanium. The residues are impure silicon and ferroaluminium containing silicon and titanium.  For the reduction of white bauxite either part of the silicon recovered by the pressing operation is returned, or sand, quartz or clay is added, to the reduction furnace together with the reducing carbon.  When red bauxite containing silica and iron oxide is treated the resulting crude alloy contains only about 60 per cent of aluminium, but a rich alloy can be recovered therefrom and considerable amounts of ferroaluminium containing silicon and titanium are recovered as a bye-product besides silicon.  The first recovered amount of silicon or ferroaluminium may be returned to the reduction furnace.  The process may be utilized to produce aluminium-silicon alloys such as "Silumin" by reducing a material poor in iron oxide such as kaolin and interrupting the process after obtaining the rich alloy.  A current density of about 10-12 amperes to the square centimetre is used in the electrothermic reduction.
