"METHOD OF COLLECTION AND DISPOSAL OF SPRAY IN THE MELTED IRON AND DEVICE FOR IMPLEMENTATION OF COLLECTION AND DISPOSAL OF SPRAY IN THE IRON". It provides for a highly efficient method of collecting and disposing of molten iron slag and a device for implementing said method; the two blades of the scoring grid installed at the front end of the cantilever beam fall side by side to some depth below the surface of the molten iron; the two grids reciprocate respectively along the surface of the molten iron; As they gradually approach each other during the reciprocating motion, the grids come together and collect the solid slag; then the two slag collecting grids are suspended to some extent above the surface, driven by the cantilever beam; and finally, the grates move away from the space above the bucket and discard the slag; the percentage of slag collection and disposal can reach over 90%; The whole process of collecting and eliminating slag takes less than 3 minutes; Consequently, iron loss can be considerably reduced in the slag collection and disposal process, with the loss rate being strictly controlled in the range of 0.1%.
