Abstract
The invention provides an emergency quick-change device for a long nozzle of a steel ladle. The device comprises a bottom plate arranged at the bottom of the steel ladle; an upper sliding plate and a lower sliding plate are arranged on the bottom plate; and a sliding plate port which is used for outflowing molten steel is respectively arranged on the upper sliding plate and the lower sliding plate. The device further comprises a quick-change cylinder; the cylinder shaft of the quick-change cylinder is connected with a short nozzle; and the upper end of the short nozzle and the upper end of the long nozzle are positioned on the same horizontal line. According to the invention, the short nozzle is used for meeting the need of emergency when the long nozzle is changed, so that the flashing of the molten steel is avoided, and meanwhile, the time for workers to change the long nozzle is ensured. To meet the need of emergency when the long nozzle is changed, the emergency quick-change device for the long nozzle of the ladle is very beneficial and practical.
Description
Technical field
The present invention relates to a kind of fast replacing device, relate in particular to a kind of continuous casting with the emergent fast replacing device of ladle long nozzle.
Background technology
Ladle mechanism is arranged on the bottom, bottom surface of ladle in casting process, and ladle mechanism is provided with long nozzle, and molten steel flow in the tundish through long nozzle; Long nozzle can produce phenomenon of rupture owing to the erosion of molten steel under long-term user mode, just need change long nozzle this moment; And must stop casting in order to change long nozzle, otherwise molten steel does not immerse tundish through the mouth of a river can cause that molten steel flashes; Be easy to make that the staff is injured, can reduce production efficiency greatly and stop casting.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of ladle long nozzle fast replacing device of meeting an urgent need is provided.
The object of the invention is realized through following technical scheme:
The ladle long nozzle fast replacing device of meeting an urgent need; Comprise the base plate that is arranged on bottom, ladle bottom surface; Said base plate is provided with slide plate up and down, offers on the said slide plate up and down to be used for the slide plate mouth that molten steel flows out, and this device also comprises a quick change cylinder; The cylinder axis of said quick change cylinder connects a short mouth of a river, and the upper end at the said short mouth of a river and the upper end of long nozzle are on same horizontal line.
Further, the above-described ladle long nozzle fast replacing device of meeting an urgent need, the upper shed diameter of the opening diameter at the wherein said short mouth of a river and long nozzle is suitable.
Beneficial effect of the present invention is mainly reflected in: produce the emergent usefulness when using the short mouth of a river as the replacing long nozzle, both avoided molten steel to flash, guaranteed that also the staff changes the time of long nozzle simultaneously.Emergent as changing long nozzle, highly beneficial practicality.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: user mode cross-sectional view of the present invention.
Wherein:
1 upper slide, 11 upper slide mouths, 2 lower skateboards
21 lower skateboard mouths, 3 long nozzles, the 4 short mouths of a river
5 quick change cylinders
The specific embodiment
The present invention has disclosed the emergent fast replacing device of ladle long nozzle, and this installs specifically in use, and is as shown in Figure 1.This comprises the base plate that is arranged on bottom, ladle bottom surface; Base plate is provided with upper slide 1, lower skateboard 2, offers the upper slide mouth 11, lower skateboard mouth 21, the two slide plate mouths that are used for the molten steel outflow up and down on the slide plate respectively and when initial position, is positioned at same straight line; At this moment, molten steel flow is maximum.This device also comprises a quick change cylinder 5, and the cylinder axis of quick change cylinder 5 connects a short mouth of a river 4, and the upper end at the short mouth of a river 4 and the upper end of long nozzle 3 are on same horizontal line.And the opening diameter at this short mouth of a river 4 is suitable with the upper shed diameter of long nozzle 3.
When long nozzle 3 fracture, only need to start quick change cylinder 5, the short mouth of a river 4 is pushed into the relevant position of long nozzle 3, simultaneously, the staff more renews long nozzle at once, through the answer of quick change cylinder 5, will lack the mouth of a river 4 and be returned to original position then.
Because the short mouth of a river 4 of the present invention is to be connected on the cylinder axis for a long time, be replaced with long nozzle directly as replacing if will lack the mouth of a river, impracticable on the contrary.This is because long nozzle is to be immersed among the molten steel of tundish always, and because new long nozzle does not use for a long time and is immersed in the molten steel, can cause by molten steel and corrode damage easily.So the present invention adopts the short mouth of a river to have practicality more.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of requirement protection of the present invention.
