Example 1
It can be seen from Figure 1, Figure 2 and Figure 3 that the ladle nozzle casting combined drainage plug is composed of a sand reservoir 2, an anastomosis cylinder 3 and two pairs of clamping plates 4 connected by screws, and a supporting sheet 5 is provided at the lower end of the clamping plate 4 , The drainage sand 1 is filled in the sand storage 2. When in use, the drainage plug is installed on the nozzle at the bottom of the ladle. The bottom of the sand reservoir is larger than the diameter of the upper part of the nozzle (not marked in the figure). It is erected on the block around the nozzle. The inverted-conical anastomotic cylinder 3 is anastomosed with the upper inner wall of the nozzle. The clamping plate 4 is pressed against the clamping plate on the opposite side by the supporting piece 5, and is tightly attached to the inner wall of the lower part of the nozzle.
It can be further seen from Figure 2 that the sand storage is composed of a plug cover 6 an...
