TORPEDO LADLE OPEN/CLOSE DOOR FOR MELTING IRON TEMPERATURE DROPS

摘要

A torpedo ladle open/close door for melting iron temperature drops is provided to minimize temperature change of the melting iron by installing an opening and closing door in the melting iron inlet side. Therefore a life of a mixer inside refractory can be to utmost lengthened. A torpedo ladle open/close door for melting iron temperature drops comprises as follows, an open/close door(110) for horizontally open and close operating in a torpedo ladle(100) entrance; a spindle(120) of one side is rotating the open/close door; an opening arm portion(111) and a closing arm portion(112) for non-power opening and closing are each projected and possessed at the open/close door; and in the mobile history of mixer on a rail movement route, an open piece(21) and a close piece(22) opening and closes opening and shutting door with the open/close arm and the selective contact of opening and shutting door to non-power are fixed on the respective rail post(20).
