Abstract
A kind of steel ladle slide board structure, belongs to continuous casting process technical field.Skateboard includes：Ladle upper nozzle, upper mounted plate, middle slide plate, bottom plate, collector nozzle of ladle.Wherein ladle upper nozzle is fixed together with upper mounted plate；Bottom plate is fixed together with collector nozzle of ladle；Ladle upper nozzle, upper mounted plate, bottom plate, collector nozzle of ladle require that through-hole diameter is identical, and through hole is entirely on the center.When controlling steel stream size, slidably reciprocated by oil cylinder, the state that middle slide plate is in controls steel stream size.Advantage is, by setting middle slide plate, secures collector nozzle of ladle and is remained stationary as in whole casting process, and the contact closing between collector nozzle and sleeve pipe is intact, it is to avoid molten steel air-breathing, improves Cleanliness of Molten Steel.
Description
Technical field
The invention belongs to continuous casting process technical field, more particularly to a kind of steel ladle slide board structure.
Background technology
Traditional steel ladle slide board structure is followed successively by ladle upper nozzle, upper slide, lower skateboard, collector nozzle from top to bottom, wherein
It is fixed between ladle upper slide and filling pipe end, it is fixed between lower skateboard and collector nozzle, before cast, sleeve pipe will be covered using manipulator
Pipe hanger is on collector nozzle, during cast, and oil cylinder pulls lower skateboard, while drive collector nozzle and sleeve pipe to slide simultaneously, passes through control
The relative position control MOLTEN STEEL FLOW size of through hole between upper slide and lower skateboard.The ladle of this two layers traditional of skateboard
Slide plate, it is necessary to control MOLTEN STEEL FLOW size is slided together with collector nozzle and sleeve pipe by lower skateboard, collector nozzle is with sleeve pipe in cunning
Easily caused during dynamic both combine it is bad the problems such as cause molten steel air-breathing, sleeve pipe anti-steel, in height in collector nozzle sliding process
External force effect is received under temperature state, the life-span is relatively low.In addition, in casting process, sleeve pipe is moved back and forth, it can cause to enter from ladle
The molten steel impact position of tundish is not fixed, and causes molten steel impingement flow to be directed at the turbulent flow that position is fixed in tundish completely
Device, once molten steel cannot be introduced into turbulator out of sleeve pipe, can influence Tundish Flow Field, and then influence steel quality.
In disclosed document, the relevant report on solving the problems, such as appeal yet there are no.
The content of the invention
It is an object of the invention to provide a kind of steel ladle slide board structure, solving steel pouring stream size must be by under slip
The problem of slide plate, collector nozzle and sleeve-like manner.
A kind of steel ladle slide board structure, including：Ladle upper nozzle 1, upper mounted plate 2, middle slide plate 3, bottom plate 4, ladle
Collector nozzle 5.Wherein ladle upper nozzle 1 is fixed together with upper mounted plate 2, it is not possible to slide；Bottom plate 4 and collector nozzle of ladle
5 are fixed together, it is not possible to slide；Ladle upper nozzle 1, upper mounted plate 2, bottom plate 4, collector nozzle of ladle 5 require that through hole is straight
Footpath is identical, and through hole is entirely on the center, and center line is maintained at straight line；The middle through-hole diameter of slide plate 3 and upper mounted plate 2 and lower solid
Fixed board 4 is identical, does not fix, and is slidably reciprocated by oil cylinder, controls steel stream size.
During the steel ladle slide board structure control steel stream size of the present invention, step is as follows：
1st, when middle slide plate 3 is in full-shut position, molten steel can not pass through collector nozzle of ladle 5, middle slide plate 3, lower fixation
Plate 4 enters in tundish；
2nd, when middle slide plate 3 is pulled open in half-open half closed state, molten steel is by ladle upper nozzle 1, upper mounted plate 2, in
Between slide plate 3, bottom plate 4, the through hole of collector nozzle of ladle 5 enters in tundish；
3rd, when middle slide plate 3 continues to pull open to full-gear, ladle upper nozzle 1, upper mounted plate 2, middle slide plate 3, under
Fixed plate 4, the intermediate throughholes of collector nozzle of ladle 5 are entirely on the center, and molten steel current global mechanism crosses ladle upper nozzle 1, upper mounted plate 2, centre
Slide plate 3, bottom plate 4, the through hole of collector nozzle of ladle 5 enter in tundish；
4th, when needing to reduce steel stream size, opposite direction promotes slide plate, reduces upper mounted plate 2, bottom plate 4 and is slided with centre
The centering degree of plate 3, until completely closing.
It is an advantage of the current invention that slide plate in the middle of by setting, secures collector nozzle of ladle and is protected in whole casting process
Hold motionless, the contact between such collector nozzle and sleeve pipe can close intact, it is to avoid molten steel air-breathing, while molten steel enters from ladle
The position of tundish keeps immobilizing, and Tundish Flow Field can be stablized, and improves Cleanliness of Molten Steel.
