Description
Technical field
The present invention relates to molding field more particularly to a kind of molding casting devices.
Background technique
Molding is a kind of traditional molten steel solidification molding production process, due to its own exclusive feature, so far still extensively
Production applied to big compression ratio, be pilot.In the molding casting process of killed steel, in order to guarantee the quality one of steel ingot
As be poured using bet method, i.e., molten steel needs to be first into feed trumpet before entering ingot mould, arrives via the running channel in chassis
Up to ingot mould bottom, from this from rise hole spray, molten steel solidifies in ingot mould again later.In addition, molten steel rises to one
After determining degree, ingot casting powder need to be covered on molten steel surface, achieve the purpose that completely cut off air, reduce heat dissipation, to prevent molten steel
Secondary oxidation and suction nitrogen, effectively control the form of shrinkage cavity in steel ingot.In traditional running gate system, as CN104399910A,
CN202591563U, CN20318458U etc., ingot mould bottom centre are often provided with one or more risings straight up
Hole, molten steel form jet stream straight up after entering ingot mould, flow back downwards from surrounding again after reaching at liquid level.This casting system
The shortcomings that system, is, it is larger to the impact in molten steel face to rise jet stream.In steel ingot of the casting compared with big cross section, due to liquid level surface area
Larger, the center surface tension is smaller, and the covering slag on liquid level surface, which is easy to be raised jet stream, to be broken through, and molten steel is caused to be exposed to
In air, causes the secondary oxidation of molten steel and inhale nitrogen, so that the reduction of steel ingot product quality.
Summary of the invention
To solve the above problems, the present invention provides a kind of molding casting device, reduces the secondary oxidation of molten steel and inhale nitrogen, mention
High ingot quality.
To achieve the above object, a kind of molding casting device of the invention, comprising:
Funnel brick, liquid steel are injected from the funnel brick；
Feed trumpet brick, the feed trumpet brick with extend in vertical direction, the upper end of the feed trumpet brick and the funnel
Brick is connected；
The top of first deflecting block, first deflecting block connects brick and the feed trumpet brick by a feed trumpet chassis
Lower end is connected；
Several second deflecting blocks, each second deflecting block pass through cross gate brick respectively and are connected with first deflecting block
It connects；
Several running channel tail bricks, the running channel tail brick are connected on second deflecting block；
The funnel brick, feed trumpet brick, feed trumpet chassis connection brick, the first deflecting block, cross gate brick, the second deflecting block with
And the inside of the running channel tail brick is sequentially connected to, and forms casting access；
In addition, being also equipped with mould bottom brick, the top of the running channel tail brick, the inside of the mould bottom brick is arranged in the mould bottom brick
Plug hole is offered, and the casting access connection of the inside of running channel tail brick described in the plug hole, the plug hole and water
Square to being in 10 °~60 ° of angle.
Preferably, the plug hole and horizontal direction are in 20 ° of angles.
Preferably, the running channel tail brick is two.
Molding casting device of the invention due to shunting and being arranged two plug holes, and is poured access end and pours with described
Infusing access is in 20 ° of angles, and in casting, two strands of liquid steel are mutually collided in sustained height, which will lead to jet energy
Dissipation, may finally reduce the rate of climb of molten steel jet stream, reduce the impact to liquid level, guarantee protection of the covering slag to molten steel
Effect improves steel ingot product quality.Especially for the casting process of the biggish steel ingot of sectional dimension, improvement effect is brighter
It is aobvious.
Detailed description of the invention
Fig. 1 is the perspective view of molding casting device of the invention；
Fig. 2 is the main view of the part A of Fig. 1；
Fig. 3 is the B-B direction cross-sectional view of Fig. 2.
Specific embodiment
In the following, being further described in conjunction with attached drawing to structure and working principle etc. of the invention.
As shown in Figures 1 to 3, molding casting device of the invention has: funnel brick 1, and liquid steel is injected from funnel brick 1；Funnel
The lower section of brick 1 connects the feed trumpet brick 2 placed vertically, and the lower end of feed trumpet brick 2 is arranged a feed trumpet chassis and connects brick 3.
The top of first deflecting block 4 connects brick 3 by the feed trumpet chassis and is connected with the lower end of feed trumpet brick 2；First
Deflecting block 4 for shunting the liquid steel that vertical direction injects in the horizontal direction, and selection splits into two in present embodiment
Road in present embodiment, is separately connected a cross gate brick 5 in the horizontal direction of the first deflecting block 4 on two sides, this is horizontal to pour
Road brick 5 is horizontal extension, is connected with the second deflecting block 6 in the other end of each cross gate brick 5.Second deflecting block 6 is equally used for
Liquid steel is shunted in the horizontal direction, to can liquidate by multiply liquid steel in casting, reaches buffering effect, this reality
It applies and equally takes two stock streams in mode, be separately connected a running channel tail brick 7, running channel in two opposite flanks of the second deflecting block 6
The top of tail brick 7 connects mould bottom brick 8, opens up plug hole 9 inside mould bottom brick 8.
In conjunction with Fig. 3, funnel brick 1, feed trumpet brick 2, feed trumpet chassis connection brick 3, the first deflecting block 4, cross gate brick 5, the
The inside of two deflecting blocks 6 and running channel tail brick 7 is sequentially connected to, and forms casting access 100, meanwhile, the interior casting with mould bottom brick 8
Hole 9 is connected, and the angle of plug hole and horizontal direction is preferably 20 °, to guarantee the spray angle when casting of liquid steel.
It,, will be due to the presence of flow angle into ingot mould when liquid steel is sprayed along casting access 100 from plug hole 9
Mutually collision occurs in subsequent flow process, collision leads to molten steel dissipation of energy, the reduction of final certifiable effluxvelocity,
Impact of the jet stream to liquid level is reduced, ingot quality is improved.
It is of course also possible to which three running channel tail bricks 7 also can be set on the second deflecting block, liquid steel is split into three bursts of progress
It liquidates, equally achievees the effect that reduce speed.
More than, schematic description only of the invention, it will be recognized by those skilled in the art that without departing from work of the invention
On the basis of making principle, a variety of improvement can be made to the present invention, this is all belonged to the scope of protection of the present invention.
