The embodiment of the invention provides an alloy feeding method and system. The alloy feeding method comprises the steps that the furnace number and the weight of molten iron waste steel are determined, the steel grade and arrival components corresponding to the furnace number are determined, and a target low-position stock bin set is determined based on the furnace number. The method comprises the following steps: calculating the types of to-be-added alloys and the weight of each alloy type based on the weight of molten iron waste steel, the steel type and arriving components, controlling an overhead bunker to discharge materials to a weighing hopper based on each alloy type, controlling the weighing hopper to discharge the alloys to a belt conveyor when the weight of the weighing hopper meets the weight of the discharged alloy type, and controlling the belt conveyor to start; and meanwhile, the unloading trolley is controlled to move to a target low-position stock bin of the target low-position stock bin s
