Abstract

The utility model relates to a sprue with a plurality of outflow openings, which comprises a plurality of metal water outflow openings, wherein the metal water outflow openings are distributed on both lateral walls of the sprue and successively arranged along the width direction. The utility model is characterized in that the outflow openings are arranged in an upswept mode. The utility model has the advantages that after the structure is used, metal water passes through the outflow openings and forms a parabolic shape, so the speed that the metal water flows into a crystallization cast roller can be slowed, and the function of stirring the metal water can be realized; thus, the temperature of metal water in a solidification area of the crystallization cast roller is reduced, and the liquid level of the metal water is stable, so the metal water can be uniformly distributed in the whole crystallization roller; therefore, the formation of stagnation areas is avoided and the quality of metal products is ensured ultimately.

Description

The cast gate that has a plurality of flow exports

Technical field

The utility model relates to a kind of pouring gate structure, especially refers to kind be distributed with a plurality of flow exports on width and broadband cast gate when being applicable to cast broad metal product.

Background technology

When the cast product, there are many factors can influence casting quality, especially the structure of cast gate.As spreading machine metal water is flowed into crystallization casting roller and is used for producing metal product when (as being with steel), the different in width that its cast gate is pressed product adopts broadband cast gate or arrowband cast gate, and the metal water flow export of more common broadband cast gate is designed to a plurality of, and be arranged in order distribution by width, as shown in Figure 3 be that flow export is arranged to two structures of portalling down.Adopt such design,, also cause the too fast phenomenon of the rate of outflow simultaneously though metal water is flowed out swimmingly.And this is for crystallization casting roller, and fast like this metal water speed can cause that crystallization roller local temperature is higher, both sides and medium temperature is on the low side, liquid level is uneven defective.The result makes metal product (band steel) surface of producing bad phenomenon such as crackle occur, reduces its qualification rate so that finally influence the quality of metal product.Obviously such cast gate still need await further improvement.

Summary of the invention

Technical problem to be solved in the utility model is the defective at prior art, provides a kind of and can slow down the metal water rate of outflow and guarantee having of metal product quality of a plurality of cast gates that go out head piece.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this cast gate that has a plurality of flow exports comprises and a plurality ofly is distributed on the cast gate two side and is arranged in order the metal water flow export of setting by width that it is characterized in that: described flow export is the setting that is inclined upwardly.

Compared with prior art, advantage of the present utility model is: after adopting said structure, metal water forms parabolic shape after by this flow export, so both can slow down the speed that flows into crystallization casting roller, can play the effect of stirring metal water again,, make metal water can be evenly distributed in whole crystallization roller so that reduce metal water temperature and steady metal water liquid level in the crystallization casting roller solidification zone, thereby avoided remaining in a standstill regional formation effectively, finally guaranteed the quality of metal product.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 partly cuts open schematic diagram for the side-looking of Fig. 1;

Fig. 3 is the structural representation of broadband of the prior art cast gate.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, when this cast gate is applied in the wide steel band of model of cast, this broadband cast gate 1 comprises a plurality of steel flow outlets 2 that are distributed on cast gate 1 two side, and these a plurality of steel flow outlet 2 widths by cast gate 1 are arranged in order setting, and each flow export 2 is the setting that is inclined upwardly.When it is installed on the spreading machine, molten steel enters inner chamber by cast gate 1 upper end, flow export 2 from its both sides flows out again, owing to flow export 2 directions upwarp, therefore, molten steel is parabolic shape after by this flow export, can slow down the speed that molten steel flows into the crystallization roller so on the one hand, the stroke that molten steel flows into that then extended on the other hand is to reduce the liquid steel temperature in the crystallization casting roller solidification zone, make molten steel in crystallization casting roller, evenly distribute, finally can guarantee quality with steel.

Claims

1, a kind of cast gate that has a plurality of flow exports, it comprises and a plurality ofly is distributed on cast gate (1) two side and is arranged in order the metal water flow export (2) of setting by width that it is characterized in that: described flow export (2) is the setting that is inclined upwardly.
