Abstract

Изобретение относитс к черной металлургии, в частности к сталеплавильному производству, и может быть использовано дл внепечной обработки стали газопорошковыми реагентами в разливочном ковше. Цель изобретени - повышение надежности и безопасности процесса продувки. В процессе продувки газопорошкова смесь поступает в общий канал, полученный внутренними поверхност ми полостей штока 6, силового цилиндра 5 с шаровой головкой, съемной вставки 8 и инжекционной трубки 7, из которого подаетс в разливочный ковш. При этом силовой цилиндр 5 установлен шарнирно на опоре 12, вращательно-подвижной относительно своей оси. 2 з.п. ф-лы, 2 ил.The invention relates to ferrous metallurgy, in particular to steelmaking, and can be used for out-of-furnace processing of steel with gas-powder reagents in a pouring ladle. The purpose of the invention is to increase the reliability and safety of the purge process. In the process of purging the gas-powder mixture enters the common channel obtained by the internal surfaces of the cavities of the rod 6, the power cylinder 5 with the ball head, the removable insert 8 and the injection tube 7, from which it is fed into the casting ladle. When this cylinder 5 is pivotally mounted on a support 12, rotationally movable relative to its axis. 2 hp f-ly, 2 ill.

Claims

Claim

1. A device for purging metal in a bucket, containing a bucket cup, upper fixed and lower movable thrust plates and casting channels 5 1668035 6 mi, a mechanism for moving the lower refractory plate in the form of a power cylinder with a rod and an injection tube, characterized in that. in order to increase the reliability and safety 5 of the purge process, the piston rod of the power cylinder of the displacement mechanism is hollow and equipped with a ball head, and the displacement mechanism has a removable hollow deaf insert, the end part of which is cone-shaped and interacts with the ball head of the rod, while the input channel is injection the tube is placed in the inner cavity of the removable insert.

2. The device according to claim 1, according to the fact that a tared spring is installed between the ball head and the stem.

3. The device according to claim 1, with the fact that the power cylinder is mounted with the possibility of rotational-translational movement about its axis.
