An injection valve which is positioned on the underneath portion of a teeming vessel is disclosed. The valve itself includes a mounting plate, and a well block nozzle which is in open communication with the metal being teemed in the vessel. Beneath the sliding injection plate a sliding plate carrier is positioned which is engaged by spring loaded rocker arms in order to maintain a compressive relationship between the sliding plate carrier, the sliding injection gate, and the stationary plate. Optionally the injection valve is fed by a plurality of injectants supplied which are adjusted by means of a control valve. In addition, wire may also be injected simultaneously with gas, or other additives. In addition, power means are provided for replacing the sliding plate carrier, and also the sliding plate. Alternatively means are provided for disengaging the rockers, and manually replacing the same.
