Meanwhile, the alloy material in the alloy trough is continuously scraped away by the blades, so that blockage is avoided.

Preferably, the bottom of the front end of the alloy chute is a circular opening, and the opening is provided with a gauze; the radius of the round opening is less than or equal to the length of the blade.

In order to ensure that the alloy material can be evenly scraped on the gauze by the blades, the radius of the circular opening is smaller than the length of the blades, so that the alloy material flattened by the blades can cover the gauze and fall into a ladle.

Preferably, the blades are in a pair and arranged in a cross shape.

The double-blade arrangement can sweep the alloy material within a short interval time, so that the alloy material is prevented from being accumulated at the blades due to too high flow speed.

Preferably, a plurality of irregularly distributed splitter cones are arranged in the alloy chute; the tip of the shunting cone faces the discharge hole.

The diffluent cone with the tip facing the discharge hole is arranged in the alloy chute, so that alloy materials flowing into the alloy chute can be scattered, the alloy materials are prevented from being blocked due to accumulation of the alloy materials, and the pressure is shared for flattening the subsequent blades.

Preferably, the included angle alpha between the top surface and the bottom surface of the splitter cone is 20-30 degrees.

The inclined plane of the spreader cone can slow down the flow velocity of the alloy material, and avoid the phenomenon that the alloy material falls into a steel ladle in a large concentration to cause uneven liquid components.

The utility model has the advantages as follows:

the utility model discloses improve the feed opening of alloy chute, through the blade with the even unloading in the accumulational alloy material shakeouts, improve the accumulational problem of alloy in the ladle, the alloy of even unloading can be annotated by the molten steel and flow and melt completely, improves the reinforced melting rate of alloy. Simultaneously the utility model discloses set up the spreader cone in the alloy chute and break up in advance to the alloy material, avoided the problem that the material pile causes the jam in the alloy chute.
