Embodiment 1
[0042] Such as Figure 1A , Figure 1B As shown, it is a top-casting manufacturing device for a super-large extra-thick plate rectangular ingot. The top-casting manufacturing device 100 is composed of a water-cooled metal mold chassis 3, a water-cooled metal mold 2, and a thermal insulation riser 1. The chassis 3 and the water-cooled Between the metal molds 2, between the water-cooled metal molds 2 and the riser 1 with heat insulation and heat preservation, the positioning seams that cooperate up and down are all placed together. The width flow distributor 4 is extended into the hollow cavity 21 of the water-cooled metal mold by adding heat insulation riser 1, such as Figure 3A , Figure 3BAs shown, the width distributor 4 includes a vertical sprue 41, and the bottom of the sprue 41 is communicated with a horizontal distribution pipe 42; the flow distribution pipe 42 is arranged along the width direction of the water-cooled metal mold 2 A plurality of spray tubes 43 vertica...
Embodiment 2
[0090] Such as Figure 9A , Figure 9B , Figure 10A , Figure 10B As shown, it is a bottom casting manufacturing device for a super-large extra-thick plate rectangular ingot. The structure and principle of the bottom casting manufacturing device 100 are basically the same as those of the top casting manufacturing device described in Embodiment 1. The difference is that the width distribution Device 4 is made of refractory brick 8 that is arranged in the groove 31 of water-cooled metal mold chassis 3. A distribution pipe 81 formed in the refractory brick 8, the distribution pipe 81 is arranged along the width direction of the water-cooled metal mold 2, and the upper side of the distribution pipe 81 is formed with a plurality of penetrating refractory bricks 8 and connected with the water-cooled metal mold The injection pipe 82 connected to the hollow cavity 21 of the hollow cavity 21; the distribution pipe 81 communicates with the straight pipe 84 arranged vertically outsid...
