Description

The wire feeding apparatus that a kind of equipment for vacuum refining is used

Technical field

The utility model relates to a kind of equipment for vacuum refining, relates in particular to the wire feeding apparatus that equipment for vacuum refining is wherein used.

Background technology

Feed the silk technology and also be the fine setting technology, the chemical ingredients of capable of regulating molten steel is a technology of widespread use in the external refining.Granted publication number is a kind of silk lifting and guiding device of feeding for the utility model patent of CN202201919U discloses, and it not have to consider to feed the vacuum-sealing in a hole, and lifting guide pipe stroke is shorter.At present vacuum refinement commonly used is with feeding the silk technology for not adding a cover the silk technology of feeding, namely behind and the vacuum breaker complete in vacuum-treat, the vacuum container cover car is left or the Mobile vacuum tank is left, feed silk to molten steel not adding a cover in the situation, this mode is easy, feed silk meeting dissipation amount of heat but uncap, overflow flue dust, be unfavorable for increasingly serious energy-conserving and environment-protective requirement; Common scheme such as accompanying drawing 1 are to shown in Figure 3, wire feeder is arranged in each station the same side, wire feeder conduit level is stretched out, the fiber tube of feeding on the vacuum container cover is 90 degree bend pipes, end band hydraucone, dock with the wire feeder conduit, the deficiency of this scheme is that the position of placing wire feeder often needs to build the watch-keeping cubicle or places other equipment, therefore only for the enough factory buildings of part arrangement space.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of wire feeder decoration form reasonable, the wire feeding apparatus of can effective space-saving equipment for vacuum refining using.

To achieve these goals, by the following technical solutions: the wire feeding apparatus that a kind of equipment for vacuum refining is used, comprise wire feeder, seal channel on the vacuum container cover, feed the silk liner, it is characterized in that: described wire feeder is arranged in the termination of station, the silk liner of feeding on the vacuum container cover comprises column, feed the fiber tube road, lift cart and actuating unit, column is fixed on the vacuum container cover, feed the fiber tube road and be fixed in lift cart top, lift cart along column vertical motion up and down, can be fed a silk hole with the downward insertion of lift cart so that feed the fiber tube road under actuating unit drives, upwards propose to feed a silk hole; Feed the fiber tube road and be made of ingress pipe and delivery line, ingress pipe is inserted in the delivery line, and ingress pipe is unidirectional 90 degree bend pipes or two-way 90 degree bend pipes, and the quantity of 90 degree bend pipes is 1,2 or 4.

Seal channel on the described vacuum container cover forms by feeding a silk hole, sealing cover and sealing cover actuating unit, feeds silk hole and sealing cover and is water-cooled, and be with sealing-ring on the sealing cover, can be under the sealing cover actuating unit drives open and close.

Sealing-ring on the sealing cover guarantees the vacuum tightness under the vacuum metling state, and seal channel and sealing cover strip water-cooled, prevents sealing cover and sealing-ring temperature distortion, vacuum tightness when impact is smelted.

The utility model can arrange that one or two wire feeders in the station end, arrange a wire feeder

The time, ingress pipe is unidirectional 90 degree bend pipes on the vacuum container cover, the open-ended direction of unidirectional 90 degree bend pipes is aimed at the conduit that level is stretched out on the wire feeder, guarantees that silk thread can pass through ingress pipe, delivery line, enters in the molten steel.When arranging two wire feeders, ingress pipe on the vacuum container cover is two-way 90 degree bend pipes, two the 90 open-ended directions of degree bend pipe are aimed at respectively the wire feeder conduit that two station end horizontal are stretched out, and guarantee can both pass through ingress pipe, delivery line at each station silk thread, enter in the molten steel.

The utility model reasonable in design, compactness, maintenance is little, reduces investment outlay, and the wire feeder decoration form is reasonable, effectively conserve space.Can use this device and under antivacuum state, feed silk to external refining devices such as VD/VOD, have promotional value in the smelting engineering.
