Furthermore, the two layers of aerogel are bonded through water glass, and one layer of aerogel is bonded with the wall-wrapping shell through the water glass.

Further, the package end includes package end shell, connects first pouring bed of material on the package end shell, and package end refractory layer is connected to first pouring bed of material top, and the package end refractory layer is built by laying bricks or stones by silicon nitride brick and fire clay and is formed, and the week side of package end refractory layer is connected with the second and pours the bed of material.

Furthermore, the aluminum flowing port comprises an aluminum flowing port shell, the inner side of the aluminum flowing port shell is bonded with a layer of aerogel, and the inner side of the aerogel is connected with a high-aluminum refractory castable layer.

Further, the ladle cover comprises a ladle cover shell, and the inner side of the ladle cover shell is connected with the high-aluminum refractory castable layer.

The utility model has the beneficial effects that: 1. the ladle wall and the ladle bottom are built by using the silicon nitride bricks and the refractory clay, and the used silicon nitride bricks are thinner than the high-aluminum refractory bricks and can reach corresponding refractory strength, so that the vacuum ladle space is larger, the weight is light, and the cost is low;

2. the service cycle of the silicon nitride brick is longer, and the silicon nitride brick cannot be bonded with residues in the ladle after being damaged, so that the cleaning difficulty of the ladle after being damaged is reduced, and time and labor are saved;

3. adopt double-deck aerogel heat preservation in the vacuum ladle wall, the aluminium mouth that flows adopts single-deck aerogel heat preservation, and it is better than current use asbestos board to carry out heat retaining effect, long service life.
