More specifically, the slag blocking boss 2 is designed at the tail part of the ladle, the width of the slag blocking boss 2 is G, G is generally equal to the width of the ladle, and the slag blocking boss can be increased or decreased relative to the width of the ladle according to the structure of the ladle. The slag stopping boss 2 is higher than the upper end face of the ladle body by A, A is more than or equal to 0, and the minimum value of A needs to be set according to the ladle structure and the inclined angle when the ladle ladles out the aluminum liquid. The slag stopping boss 2 is provided with a molten liquid inlet and outlet, molten metal enters from the molten liquid inlet and outlet when the ladle scoops out molten aluminum, the distance between the inlet and outlet and the top end of the slag stopping boss 2 is B, the height of the inlet and outlet is C, and the width of the inlet and outlet is D, which are all set as required. The ladle fixing boss 5 is arranged on one side of the ladle, and the ladle fixing screw hole and the ladle positioning groove are arranged on the ladle fixing boss, so that the ladle is fixed on the relevant connecting moving part through bolts, and the ladle can move. A slag trap 4 is arranged near a ladle nozzle at the upper part of the ladle, the height F and the depth E of the slag trap 4 are set as required, and the distance H between the slag trap 4 and the ladle nozzle is also set as required.

In a method for scooping clean metal solution by using the ladle, the ladle is inclined by X degrees to scoop aluminum liquid from the metal melt in the holding furnace, at the moment, the slag blocking boss 2 of the ladle is higher than the upper end surface of the ladle by P which is more than 0, so that the melt in the holding furnace can only enter the ladle from the melt inlet and outlet of the ladle. Therefore, the value A in FIG. 1 needs to be set according to the ladle structure, the weight reduction requirement of the ladle and the inclined angle X degree when the ladle ladles out the molten aluminum, and the horizontal height of the slag blocking boss 2 is always higher than the root of the slag blocking boss 2 connected with the upper end surface of the ladle. The depth of the ladle immersed into the molten metal is ensured to be higher than the upper end surface of the molten metal inlet and outlet but lower than the root of the slag-stopping boss 2 connected with the upper end surface of the ladle through the slag-stopping boss 2. The molten metal can only enter the ladle from the molten metal inlet and outlet, and a metal oxide layer and other slag particles on the surface layer of the molten metal in the heat preservation furnace are blocked by the slag blocking boss 2 and cannot enter the ladle, so that the ladle obtains primary clean molten metal. Meanwhile, the size of the melt inlet and outlet, namely the B, C, D value in fig. 1 and 2, can be adjusted according to the process requirements to achieve the required process effect.

In the method for casting the clean metal solution by using the ladle, the melt scooped by the ladle is transferred to the upper part of a casting die for casting, the ladle is rotated by taking a ladle nozzle as a center for casting, and the liquid flow passing through the ladle nozzle is always higher than the bottom surface of a slag baffle plate 4, so that a secondary oxide layer of the metal floating on the surface layer of the melt in the ladle is blocked, the secondary oxide layer cannot flow into the piston casting die along with the melt, and the clean melt is cast by the ladle. Accordingly, the relative size E, H of the slag trap 4 is determined by the casting process requirements for melt flow rate, etc. to ensure that the flow through the ladle nozzle is always above the bottom surface of the slag trap 4. The purpose of F is to prevent the metal oxide layer from passing over the slag trap 4 from the slag trap 4 into the casting mold when the slag trap 4 traps and accumulates the metal oxide layer, so that F > 0.
