Method and device for producing ferroalloy by mechanical crushing

The invention discloses a method and a device for producing ferroalloy by mechanical crushing, which is used for producing ferroalloy products in a high-efficiency and low-consumption way. The method and the device are characterized by comprising the following steps of firstly, melting a ferroalloy raw material, casting the ferroalloy raw material into a wedge gap of a continuous-casting roll through a nozzle, gradually adjusting a seam of the continuous-casting roll when the molten iron is solidified and formed in the continuous-casting roll, meanwhile, setting the rotation speed of the continuous-casting roll to 2-20m/min, and continuously casting and rolling, so as to form a plate blank; adjusting the temperature of the plate blank in a cooler to 800-950 DEG C, enabling the plate blank to sequentially pass through a longitudinal slitting rolling roll and a transverse slitting rolling roll, carrying out slitting rolling on the plate blank to form a grid plate with longitudinal and transverse impressions, ca
