The invention provides slag collecting and conveying equipment and a slag collecting and conveying method, and relates to the technical field of smelting slag treatment. The slag collecting and conveying equipment comprises a collecting device and a conveying device, the collecting device is arranged below a slag discharging port of an electric furnace and used for collecting slag generated by theelectric furnace, the conveying device communicates with the collecting device and slag treatment equipment, and the conveying device is used for conveying the slag in the collecting device to the slag treatment equipment. Through the arrangement of the collecting device and the conveying device, frequent conveying in the slag treatment process can be avoided, assembly line type operation is adopted in slag treatment, the problem about automobile reshipment cannot be involved, the in-plant material transportation burden and the labor cost are reduced, and accordingly cost is reduced.
