Description
Technical field
The utility model relates to a kind of improvement of tundish, specifically a kind of tundish water nozzle flow control device.
Background technology
Tundish is a refractory material container of using in the steelmaking process, at first accepts to water the molten steel that gets off from ladle, and then is assigned in each crystallizer by middle water containing opening and goes, and gets into continuous casting working procedure.Present tundish flow control device comprises the mouth of a river and stopper, and the middle part at the mouth of a river is a runner; The inclusion of tundish is made up of refractory material working lining, permanent layer and heat-insulation layer, and the refractory material working lining is located on the madial wall of permanent layer, and the outer wall of permanent layer is provided with heat-insulation layer; The mouth of a river is fixed on the bottom of inclusion, through operating mechanism stopper is placed in the inclusion, stopper be positioned at the mouth of a river directly over; The upper edge at the mouth of a river is equal with the inner chamber diapire of inclusion, and described stopper bottom is a round convex type, and the top at the mouth of a river is the circle matrix; In casting process,, regulate stopper and move down through operating mechanism; The lower end of stopper is inserted in the upper edge at the mouth of a river, so that the flow of control molten steel, promptly through regulating spacing between the stopper and the mouth of a river with control steel stream.Its weak point is: the one, and after using certain hour, owing to receive the erosion and the impact of impurity in molten steel and the molten steel, stopper is sharpened easily; Become taper by round convex type; Sometimes the caput position becomes piece to come off, and loses the effect of control stream, and the piece that comes off simultaneously can stop up molten steel channel; The 2nd, steel flow is when the mouth of a river, and field trash is attached on the wall of the mouth of a river in the molten steel, and nozzle blocking takes place easily.These field trashes have multiple source: the deoxidation products of first refining and refining process, and molten steel generation secondary oxidation product, ladle slag, middle cinder inclusion, covering slag are involved in, and calcium is dealt with the high-melting-point field trash of generation etc. improperly.The sticking of aluminate inwall at the mouth of a river, dross, expansion are the main causes that results in blockage in the molten steel.The harm that middle water containing opening stops up has the following aspects: (1), nozzle blocking are prone to cause casting to finish too early, reduce to connect watering property and conticaster efficient; (2), in the process that tamper produces, tundish slide plate aperture can become greatly, the crystallizer liquid level fluctuation of molten steel is excessive, is easy to generate bleed-out and the cc billet surface quality problem of cohering; (3) back gets in the molten steel if tamper comes off, and influences the degree of purity of molten steel, forms large-scale field trash easily, and the strand inherent quality is had a strong impact on, and the intensity of steel and toughness are sharply descended; (4), nozzle blocking makes that the conticaster pulling rate is compelled to be reduced, the tamper that sticks in the mouth of a river can cause bias current, washes away on the tamper peeling off under to float in the covering slag, the composition of change covering slag makes its mis-behave, causes the slab quality defective.
Summary of the invention
The purpose of the utility model is to provide a kind of operation simple in structure, easy to use, easy, can effectively control molten steel flow, effectively prevents the tundish water nozzle flow control device of nozzle blocking.
In order to reach above purpose, the technical scheme that the utility model adopted is: this tundish water nozzle flow control device comprises the stopper and the mouth of a river; The mouth of a river is fixed on the inclusion bottom of tundish, and the middle part at the mouth of a river is provided with runner, directly over the mouth of a river, is provided with stopper; Stopper is positioned at the inclusion chamber; It is characterized in that: be provided with on the top at the mouth of a river to the protruding boss of inclusion inner chamber, the lower end of stopper is provided with groove, and groove covers on the outer wall of boss.
The utility model is also implemented through following measure: described groove is the hemispherical of indent, and the outer wall of boss is identical with the radian of groove.
The upper edge of described boss is than the high 2-15 of plate inner wall centimetre of inclusion; The boss and the mouth of a river are made into integral structure.
The beneficial effect of the utility model is: operation simple in structure, easy to use, easy, can effectively control molten steel flow, and effectively prevented nozzle blocking, prolonged the service life at the stopper and the mouth of a river, reduced production cost.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of the utility model;
Among the figure: 1, inclusion; 2, stopper; 3, the mouth of a river; 4, boss; 5, groove; 6, runner.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.This tundish water nozzle flow control device comprises the stopper 2 and the mouth of a river 3, and the mouth of a river 3 is fixed on inclusion 1 bottom of tundish; The middle part at the mouth of a river 3 is provided with runner 6, directly over the mouth of a river 3, is provided with stopper 2, and stopper 2 is positioned at inclusion 1 chamber; It is characterized in that: 3 top is provided with to the protruding boss 4 of inclusion 1 inner chamber at the mouth of a river; The lower end of stopper 2 is provided with groove 5, and the shape of the shape of groove 5 and boss 4 is suitable, and groove 5 covers on the outer wall of boss 4.
Described groove 5 is the hemispherical of indent, and the outer wall of boss 4 is identical with the radian of groove 5.
The upper edge of described boss 4 is than the high 2-15 of plate inner wall centimetre of inclusion 1; Boss 4 is made into integral structure with the mouth of a river 3.
When using the utility model, stopper 2 can free lifting by mechanism controls, when stopper 2 falls; The groove 5 of stopper 2 lower ends covers on the boss 4 on 3 tops, the mouth of a river, and fits together, and stops molten steel to get into runner 6; When stopper 2 was mentioned, molten steel was earlier from stopper 2 lateral current downflow, again along the outer wall of boss 4 to the upper reaches; Get into runner 6 from the gap location between groove 5 inwalls and the boss 4 at last and flow out, formed backflow like this, slowed down flow velocity; The phenomenon that stopper 2 caput positions are sharpened can be prevented, to a certain extent, the nozzle blocking phenomenon can be prevented.
