Pouring base plate

The invention discloses a pouring base plate. The pouring base plate comprises a base plate body and a flow control shutoff device. An accommodating cavity is formed in the base plate body. The base plate body is provided with a runner brick hole which extends to the upper surface of the base plate body and communicates with the accommodating cavity. The flow control shutoff device comprises a runner brick, a sliding plate capable of sliding horizontally, a flow guiding body and a push rod capable of doing push-pull motion; the runner brick is arranged in the runner brick hole; the sliding plate and the flow guiding body are both arranged in the accommodating cavity; the runner brick, the sliding plate and the flow guiding body are sequentially sealed and attached from top to bottom; at least part of the horizontal projection of a lower end opening of a runner hole of the runner brick and at least part of the horizontal projection of an upper end opening of a flow guiding channel of the flow guiding body are overlapped; one end of the push rod is detachably connected with the sliding plate, and the other end of the push rod is located outside the base plate body; and the push rod drives the sliding plate to slide horizontally, and the runner hole and a flow passing hole of the sliding plate can communicate with the flow guiding channel vertically to form a pouring channel. The pouring base plate can control the flow rate and can also shut off the pouring channel, so that a continuous steel column is prevented from being formed.
