Abstract
The utility model relates to a tundish stopper rod slag-isolating device comprising a sleeve and an upper edge on the top end thereof, wherein the inner diameters of both the sleeve and the upper edge are greater than the diameter of the stopper rod and the outer diameter of the upper edge is greater than the bore diameter of the stopper rod of the tundish. The tundish stopper rod slag-isolating device has simple structure and convenient application, and can effectively prevent the stopper rod from being corroded so as to reduce accident rates.
Description
Technical field
The utility model relates to a kind of device of protecting stopper, particularly relates to a kind of tundish stopper dregs separating device.
Background technology
For using stopper to control the tundish of stream, the contact surface of stopper and molten steel is furnished with coverture, and coverture very easily produces corrosiveness to stopper, and serious meeting causes stopper to rupture in the slag line position.For alleviating this corrosion phenomenon, need constantly to change tundish molten steel charge weight in the casting process, but frequently changing the tundish molten steel liquid level will cause the interior molten steel flow field of tundish to change, and then the probability that causes rolling up slag increases, worsened steel quality, after the water yield reduction of middle Baogang, cause working lining to collapse for the tundish that adopts the dry type material as working lining on the other hand, reduced tundish service life.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, easy to use, the tundish stopper dregs separating device that can effectively protect stopper not to be corroded.
In order to address the above problem, the utility model by the following technical solutions:
A kind of tundish stopper dregs separating device comprises the upper edge on sleeve and top thereof, and the internal diameter of sleeve and upper edge is greater than the stopper diameter, and the upper edge external diameter is greater than the aperture in tundish stopper hole.
The integral structure design is adopted in sleeve and upper edge.
Compared with prior art, the beneficial effects of the utility model are:
By using the tundish dregs separating device to reduce the generation probability of volume slag greatly, prevent the casting process stopper corrode seriously cause producing interruptions, bakie working lining collapses and produces in the phenomenon that crusts of the stopper position of appearance, improve tundish liquid automatic control precision, improved and steel quality and production efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of tundish stopper dregs separating device, the employing refractory material is made, assurance has enough anti-slag abilities, as shown in Figure 1, the upper edge 1 that comprises sleeve 2 and top thereof, the integral structure design is adopted in sleeve 2 and upper edge 1, and the internal diameter of sleeve 2 and upper edge 1 is greater than the stopper diameter, and upper edge 1 external diameter is greater than the aperture in tundish stopper hole.
Before the tundish baking tundish mop is placed on the stopper hole; Open and drop into tundish covering flux 3 when tundish weight 18 ton hours after watering; Stablize liquid level to the working depth when middle Baogang water liquid level and between mop and stopper, drop into 5kg fritting covering slag and prevent secondary oxidation, add the 10kg carbonization rice husk simultaneously and prevent the coverture crust; Mop can be struck in the residual bag of input of having no progeny after producing end.
Claims (2)
