Automatic hollow dummy bar head with guide structure

An automatic hollow dummy bar head with a guide structure effectively solves the problem that deviation is prone to occurring due to the fact that no guide exists between the dummy bar head and a crystallizer. Comprising a cylindrical body, a partition plate is arranged in the body and divides the interior of the body into an upper cavity and a lower cavity, a circular truncated cone is arranged above the upper cavity, a connecting rod is arranged in the middle of the lower cavity, the upper edge of the outer side of the body extends outwards to form an outer edge, a plurality of guide blocks are evenly distributed below the outer edge, the lower portions of the guide blocks are of cuboid structures, and the upper portions of the guide blocks are of triangular block structures. The included angle between the outer side surface of the triangular block and the vertical surface is 15 degrees; the dummy bar head is simple and ingenious in structure and convenient to use, the guide structure is arranged on the dum
