Abstract

The utility model relates a special spur with multiple spouts, comprising metal solution spouts distributing on both sides of the spur and setting stone out in width, a prominence provided inside the middle of the housing used for diffluencing, wherein the spouts uptilt. Adopting the structure, metal solution forms a smooth parabola after flowing out the spout, which slows down the speed of flowing into a crystal roller, and to stir metal solution, that reduces the temperature of freezing area in the crystal roller, and steadies the level of metal solution, makes metal solution distribute in the whole crystal roll equably, so stagnation zone is prevented from forming to guarantee the quality of metal products.

Description

A kind of 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 the sort ofly be distributed with a plurality of flow exports and be applicable to the broadband cast gate of cast broad product on width.

Background technology

When the cast product, there are many factors can influence casting quality, especially the structure of cast gate.Metal water is flowed into the crystallization roller and be used for producing metal product when (as being with steel) as spreading machine, 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 the crystallization roller, and fast like this metal water flow velocity can cause that crystallization roller local temperature is higher, both sides and medium temperature is on the low side, liquid level is irregular 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 need 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 the cast gate that has a plurality of flow exports of metal product quality.

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: (1) described flow export is the setting that is inclined upwardly; (2) in the middle of the cavity of cast gate, be provided with the special projection of shunting usefulness.

Compared with prior art, advantage of the present utility model is: after adopting said structure, metal water forms parabolic shape stably after by this flow export, so both can slow down the speed that flows into the crystallization 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 effectively avoided remaining in a standstill regional formation, finally guaranteed the quality of metal product.

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, 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.And in the middle of the cavity of cast gate, projection 3 is arranged, play shunting action.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 stably 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 with the liquid steel temperature in the solidification zone that reduces the crystallization roller, make molten steel on the crystallization 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 notch (2) of setting by width, it is characterized in that:

A. described flow export (2) is the setting that is inclined upwardly;

B. in the middle of the cavity of cast gate (1), be provided with the projection (3) of shunting usefulness.
