Stream inoculation manual control method

The invention relates to a stream inoculation manual control method which is characterized in that a stream inoculation hopper is arranged above a water outlet of a casting ladle, the inoculation hopper is provided with a feed port and a discharge port, a cone valve is arranged in the inoculation hopper to block the discharge port, and a cone section of the cone valve and a cone section of the inoculation hopper are arranged in a shape following mode; the discharging amount of the inoculation hopper is controlled by adjusting the height of the cone valve; a first support is arranged on the top of the casting ladle, and the inoculation hopper is rotatably supported above a water outlet of the casting ladle through the first support. According to the stream inoculation manual control method, the stream inoculation angle and the stream inoculation amount can be effectively controlled, the adding angle and the adding amount of the inoculant can be synchronously adjusted at any time in the pouring process, uniform
