ARRANGEMENT FOR CUTTING OFF FLAME AND PLUGGING OUTLET ORIFICE OF METALLURGICAL ASSEMBLY

摘要

FIELD: metallurgy. SUBSTANCE: invention is aimed at developing arrangement structure to cut off slag and plug taphole requiring diminished space into depth and allowing sprinkling of smelt to be reduced. Arrangement has supporting unit installed in bottom section near the taphole coupled with pneumatic system and provided with a drive consisting of at least one pneumatic cylinder. Arrangement has further a lever with its load-bearing end pivotally installed in supporting unit with drive from pneumatic cylinder. Free end of lever has a cap in the form of sprayer with air nozzle and provided with channel to transmit compressed air from pneumatic system through supporting unit into the cap nozzle. The lever is made as a hoop with its load-bearing end installed on pivot shaft in supporting unit located in the plane going through taphole channel axis in such a manner that the cap in its initial position were disposed next to the taphole and its nozzle channel were directed perpendicularly to the taphole channel and, when swiveled into working position, nozzle channel, coaxial with taphole channel, enters taphole opening. EFFECT: improved design.
