The invention discloses a device for ferroalloy water-quenching granulation, and the device comprises a ladle for containing molten iron, a launder, a granulation water tank and a water circulation system, wherein the ladle is arranged on one side of the launder, the launder is arranged at the upper inclined part of the granulation water tank, and the water circulation system is connected with the granulation water tank. The invention further discloses a process technology which utilizes the ferroalloy water-quenching granulation device to perform ferroalloy water-quenching granulation. By adopting the device and the process, a controller can be far away from the granulation water tank, the on-site operation of the controller is not required during a granulation process, and the safe operation of the granulation process can be ensured to a greatest extent. By adopting the method, about 500-1000kg of the molten iron can be granulated per minute, and the particle size of products can be controlled at 10-80cm (a
