Abstract
The utility model discloses a pouring die for twin-roll casting strips. A T-shaped pouring channel is arranged in the pouring die and consists of a direct pouring channel (1) and a transverse pouring channel (2) a group of flow gates (3) are arranged on the transverse pouring channel (2) and penetrate the direct pouring channel (1). The diameter of the flow gate from the middle axis of the transverse pouring channel of the pouring die to the outside is gradually enlarged, which certainly complements the influence on the flowing speed caused by the resistance of friction of a tube wall during the floating process of liquid steel; therefore, the flow of the liquid steel in each flow gate is integrally uniform; therefore, the thickness of the strips is consistent, which guarantees to continuously output casting strips with stable quality, and realizing large-batch continuous industrial production.
Description
Technical field
The utility model relates to casting mold, is specifically related to a kind of casting mold of double-roller rolling strip steel.
Background technology
As everyone knows, double-roller rolling strip steel is that high-temperature molten steel directly is poured between a pair of counterrotating casting roller; The casting roller is the crystallization roller again, leaves 1～6mm roll gap between two rollers, and the rotation of casting roller reaches speed 0～150m/min, and its inside is connected with recirculated water; In strip casting process, molten steel is without interruption, and the molten steel one side flows downward along two rollers (casting roller), one side crystallization under the cooling of inside, and the steel band of crystallization simultaneously is subjected to roll-force between two rollers, under above-mentioned comprehensive effect, the output that the strip steel is continuous; As from the foregoing, produce continuously in order to reach the strip steel, molten steel must be by the quantitative supply system of a cover, i.e. casting mold, and casting mold is two rollers an amount of molten steel output strip steel without interruption; As without interruption too many, molten steel overflows along two roller end side seal places, thereby tape edges is obstructed and is difficult to normal casting; As molten steel deficiency without interruption, produce the casting accident and cause broken belt, casting can not be carried out continuously; Existing casting mold, outside molten steel flow velocity is slack-off from the axis, and the molten steel liquid outlet quantity is gradually little, and mass flow discrepancy is even, causes strip steel variable thickness to cause, and board quality is poor.
Summary of the invention
The purpose of this utility model is: the casting mold that a kind of double-roller rolling strip steel is provided, casting mold combines with liquid steel level control in the course of the work, reach molten steel suitably supply continuously, guarantee the continuous output of cast strip, the realization large-batch industrial is produced continuously.
Technical solution of the present utility model is: establish T shape gate in casting mold, T shape gate is made up of sprue and cross gate, and the one group of ingate that distributes on the cross gate connects sprue.
In the casting mold of double-roller rolling strip steel of the present utility model, ingate is double row.
In the casting mold of double-roller rolling strip steel of the present utility model, the downward 15 ° of inclinations of ingate.
In the casting mold of double-roller rolling strip steel of the present utility model, the centre-to-centre spacing of per two ingates is the 80-100 millimeter.
In the casting mold of double-roller rolling strip steel of the present utility model, the diameter of the ingate that the axis of cross gate is outside is gradually big.
In the casting mold of double-roller rolling strip steel of the present utility model, the cross gate width is 100 millimeters of strip steel plate reductions.
In the casting mold of double-roller rolling strip steel of the present utility model, the cross gate diameter adds 5 millimeters for the sprue diameter.
In the casting mold of double-roller rolling strip steel of the present utility model, the ingate gross area equals the cross gate area.
In the casting mold of double-roller rolling strip steel of the present utility model, casting mold is installed in 450-700 millimeter place, casting roller top.
The diameter of the ingate that the axis of the cross gate of casting mold of the present utility model is outside is gradually big, the liquid outlet quantity of molten steel is also gradually big, and the molten steel flow is evenly whole, strip steel consistency of thickness, the continuous output of the cast strip that guaranteed quality is stable, the realization large-batch industrial is produced continuously.

In the casting mold of double-roller rolling strip steel of the present utility model, ingate 3 downward 15 ° of inclinations.
In the casting mold of double-roller rolling strip steel of the present utility model, the centre-to-centre spacing of per two ingates is the 80-100 millimeter.
In the casting mold of double-roller rolling strip steel of the present utility model, the diameter of the ingate 3 that the axis of cross gate 2 is outside is gradually big.
In the casting mold of double-roller rolling strip steel of the present utility model, cross gate 2 width are 100 millimeters of strip steel plate reductions.
In the casting mold of double-roller rolling strip steel of the present utility model, cross gate 2 diameters are that sprue 1 diameter adds 5 millimeters.
In the casting mold of double-roller rolling strip steel of the present utility model, ingate 3 gross areas equal cross gate 2 areas.
In the casting mold of double-roller rolling strip steel of the present utility model, casting mold is installed in 450-700 millimeter place, casting roller top.
