Abstract
The utility model is related to a kind of thin strap continuous casting convection type flow distribution devices, the flow distribution device includes feed pipe, two semicircle runner pipes, heating equipment and discharge nozzle, the area of the upper surface of the feed pipe is more than the area of the lower face of the feed pipe, the upper end of two semicircle runner pipes is connected to the feed pipe, two semicircle runner pipes are about the substantially symmetrical about its central axis of feed pipe, the tangent line of the lower end of the semicircle runner pipe is vertical with plumb line, the lower end of two semicircle runner pipes is connected to the discharge nozzle, cavity is formed between two semicircle runner pipes, the heating equipment is arranged in the inside of the cavity, it is both provided with multiple discharge holes on the opposition side wall of the discharge nozzle.In the utility model, molten steel is just opposite from the direction that two semicircle runner pipes flow out, so the power of the molten steel of outflow is canceled each other out, in this way, smaller to the impact of the liquid level in bath.
Description
Technical field
The utility model is related to strip continuous casting technology field, especially a kind of thin strap continuous casting convection type flow distribution device.
Background technology
A kind of continuous casting steel machine ironmaking technology of nearly end form, its direct pouring thickness 15mm strip base below, no longer through heat
It rolls and direct cold rolling is at band.The method for exploring direct pouring plank can trace back to for 19th century.This thought is proposed earliest
It is Bessemer, the thin plate of successfully cast with injection technology at the top of double roller for 1856 steel and malleable cast iron.Hereafter development uses
A variety of testing programs, since non-ferrous metal fusing point is low so that the steel rolling of non-ferrous metal thin strap continuous casting enters the production phase earlier.It will
After molten steel is injected into tundish, molten steel is assigned in current distribution device by the mouth of a river, then two water cooling crystallizations are injected by current distribution device
In the bath that roller is surrounded with side seal board, on the surface of two crystallization rolls, gradually solidification forms green shell to molten steel, connects in two crystallization rolls
After line nearby solidifies completely, rolling effect occurs by two rotating backward for rollers, forms the cause with certain thickness and width
Close metal tape.Existing molten steel can cause liquid level fluctuation from being injected into current distribution device in bath, or more than calmness, at this time
Will update that is cracked or being unfavorable for bath top molten steel, influence product quality.
Invention content
The purpose of this utility model is to provide for a kind of thin strap continuous casting convection type flow distribution device.
The technical solution of the utility model is：A kind of thin strap continuous casting convection type flow distribution device, the flow distribution device include into
Expects pipe, two semicircle runner pipes, heating equipment and discharge nozzle, the area of the upper surface of the feed pipe are more than the feed pipe
Lower face area, the upper end of two semicircle runner pipes be connected to the feed pipe, and two described semicircle to flow
Siphunculus is about the substantially symmetrical about its central axis of feed pipe, and the tangent line of the lower end of the semicircle runner pipe is vertical with plumb line, described in two
The lower end of semicircle runner pipe is connected to the discharge nozzle, and cavity is formed between two semicircle runner pipes, described to add
Hot equipment is arranged is both provided with multiple discharge holes on the inside of the cavity, the opposition side wall of the discharge nozzle.
A kind of above-mentioned thin strap continuous casting convection type flow distribution device, the heating equipment are coil heats equipment.
The utility model has the beneficial effects that：The utility model molten steel is from the direction that two semicircle runner pipes flow out
It is just opposite, so the power of the molten steel of outflow is canceled each other out, in this way, smaller to the impact of the liquid level in bath.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of the utility model discharge nozzle.
In figure：1. feed pipe, 2. semicircle runner pipes, 3. heating equipments, 4. discharge nozzles, 41. discharge holes, 5. cavitys.
Specific implementation mode
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, which includes the semicircle runner pipe of feed pipe 1, two
2, heating equipment 3 and discharge nozzle 4, the area of the upper surface of the feed pipe 1 are more than the area of the lower face of the feed pipe 1,
The upper end of two semicircle runner pipes 2 is connected to the feed pipe 1, and two semicircle runner pipes 2 are about described
Feed pipe 1 it is substantially symmetrical about its central axis, the tangent line of the lower end of the semicircle runner pipe 2 is vertical with plumb line, and molten steel is from described in two
Direction when semicircle runner pipe 2 flows out is just opposite, so the power of the molten steel of outflow is canceled each other out, in this way, to bath
The impact of interior liquid level is smaller.
The lower end of two semicircle runner pipes 2 is connected to the discharge nozzle 4, two semicircle runner pipes 2
Between form cavity 5, the heating equipment 3 is arranged in the inside of the cavity 5, and molten steel physical property when temperature is relatively low can be sent out
Changing, so heating equipment 3 can ensure that the physical property of molten steel does not change.
Be both provided with multiple discharge holes 41 on the opposition side wall of the discharge nozzle 4, the setting of the discharge hole 41 it is described go out
The side wall of expects pipe 4, it is possible to reduce the impact to liquid level in bath.
A kind of above-mentioned thin strap continuous casting convection type flow distribution device, the heating equipment 3 are coil heats equipment.
The embodiment created above to the utility model is described in detail, but the content is only the utility model wound
The preferred embodiment made, should not be considered as limiting the scope of the present invention.It is all to create range according to the utility model
Made by all the changes and improvements etc., should all still belong within this patent covering scope.
