Embodiment 1
[0026] Such as figure 1 As shown, the anti-oxidation casting equipment for B30 alloy ingots includes a hearth, an ignition device and a crystallizer. The hearth is arranged above the ignition device. The hearth includes a furnace head 3; 6; the ignition device includes a furnace pan 7 arranged on the top of the ignition device, and a plurality of fire distributor nozzles 8 are arranged on the upper surface of the furnace pan 7, and the adjacent fire distributor nozzles 8 are spaced at 5-10mm intervals, and are distributed in a ring to form a firearm; the ignition device furnace The plate 7 near the crystallizer 2 is provided with a high-temperature-resistant glass window 9; the temperature-measuring probe 10 and the oxygen concentration detector 11 are respectively installed on both sides of the high-temperature-resistant glass 9 window position, and the furnace plate 7 is connected to the crystallizer mold through a quick-loading structure. The base 12 is sealed with a high t...
Embodiment 2
[0028] A method for anti-oxidation casting of B30 alloy ingot, comprising the following steps:
[0029] 1) Crystallizer preparation: raise the dummy table (1) into the cavity of mold 2, and overlap with the bottom of mold 2 by 20-40 mm, and use asbestos rope to fill the mold 2 and dummy ingot layer by layer in the same direction The gap between the tables 1; the crystallizer 2 is a graphite crystallizer with a height of 200-250mm and an inner diameter of 182-184mm;
[0030] 2) Ironing furnace head: tilt the furnace platform so that the copper liquid immerses the furnace head, control the temperature of the furnace head to 1200-1350 ° C, melt the residual metal on the stopper 4, the bottom bowl 5, and the pouring pipe 6 to ensure that the ingot is cast The normal rotation of the stopper rod 4, the stopper rod 4 and the bottom bowl 5 are in good condition, and the copper liquid flow can be adjusted normally; the stopper rod 4, the bottom bowl 5, and the pouring pipe 6 are all ma...
