Abstract
The utility model relates to a vortex-proof runner of a bakie for continuous casting. The utility model is provide with a bell-mouth funnel-shaped inner cavity. The inner wall of a bell mouth is provided with a key groove-shaped or corrugation-shaped concave and convex surface. The utility model can effectively prevent a continuous casting bakie from generating molten steel vortex during a low level pouring. The casting quality can be ensured. The loss of casting molten steel can be lowered.
Description
The utility model belongs to the metallurgical equipment parts, relates to a kind of metering nozzle of making of refractory material on the continuous casting tundish.
Conventional continuous casting tundish metering nozzle is the smooth horn mouth infundibulate of being made by refractory material of inner wall smooth, in the cast later stage, when liquid steel level is reduced to certain liquid level in the tundish, can produce the molten steel vortex, and vortex can be involved in the slag on the molten steel face in the molten steel, has a strong impact on the quality of casting steel billet.For fear of the generation of molten steel vortex, have to before the tundish liquid steel level is reduced to certain liquid level, stop cast, with regard to residue molten steel in the tundish being not used and becoming steel scrap, improved production cost like this.
The purpose of this utility model provide a kind of under low liquid level cast can prevent to produce the continuous casting tundish metering nozzle of molten steel vortex.
The technical scheme that realizes above-mentioned purpose is: the horn mouth inwall that will have in the continuous casting tundish metering nozzle of horn mouth infundibulate inner chamber is made longitudinal key flute profile or corrugated concavo-convex wall.
Accompanying drawing 1 is the positive sectional structure schematic diagram of the utility model.
Accompanying drawing 2 is a plan structure schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model can adopt refractory material integral die, sinter molding.But in order to improve finished product rate and quality, reduce production costs simultaneously, can make overcoat and inner core respectively, inlay then, boning is combined into one by different refractory materials.General overcoat 1 is made by high alumina refractories, and inner core 2 adopts the higher zirconia refractory of refractoriness, and the horn mouth 5 and the straight length 4 of inner core 2 also can discretely be made, and the inwall of horn mouth 5 is made the concavo-convex wall 6 of longitudinal key flute profile.Binding agent 3 between overcoat 1 and the inner core 2 adopts zirconium matter high-temperature adhesives.
The utility model is simple and reasonable for structure, can prevent effectively that the continuous casting tundish from producing the molten steel vortex when low liquid level is poured into a mould, thereby guarantee the casting quality, reduces the loss of casting molten steel greatly.
