Filed: 1945-09-04
Abstract: 608,232. Continuous ingot casting-machines. JACQUET, J. F. A. Sept. 4, 1945, No. 22756. Convention date, Feb. 11, 1943. [Class 83 (i)] In a machine for casting ingots of indefinite length having a pot 1 connected to one or more horizontal cooled moulds 13, each of which contains a plug 19, each mould is connected to a vertical hole in a brick 9 in the bottom of the pot via a refractory horizontal conduit 11 having the same section as the mould and arranged in a box 10 which is open at the top and is detachably secured to the base 3 of the pot so that it can be removed if the whole freezes up solid with metal in the pot. Molten metal is poured into the conical pot 1 resting on the base 3, both being lined with refractory material 2. The hole in the brick 9 is closed by a refractory plug 25 resting on the plug 19 arranged in the water-cooled mould 13 and the conduit 11. The molten metal may be covered with charcoal dust and then if desired a cylinder 4, containing a temporarily-fixed piston 7 with a conical extension 8 faced with bricks 20 and surrounded with a mixture of powdered dolomite and tar or other plastic material P, is moved on rollers 5 and rails 6 into position over the pot 1. A weight or a fluid pressure or mechanically-operated ram 28 is then applied to the piston 7 which has been released from its cylinder and rollers 18 are rotated to withdraw the bar 19. This allows the plug 25 to fall into a recess in a brick 12 and the molten metal to flow into the mould, become solid, and be withdrawn by the rollers. The bricks 20 are backed by sand 23 and a weight 24. If the metal should solidify in the passage leading from the pot to the mould, the casing 10 is detached from the base 3 and, if necessary, this from the pot 1, the bricks are broken away and the solidified metal cut away by a blowpipe &c. The mould may be made of aluminium silicon or aluminium copper alloys of the kind known under the Registered Trade Marks " Alpax " and " Duralumin " and be strengthened by a winding of steel wire. In a modification one pot has a number of moulds and these may be arranged so that two or more co-operate with one pair of rollers and another set of moulds arranged in another horizontal direction co-operate with another pair.
