Description
Technical field
The utility model relates to thin strap continuous casting equipment, particularly the thin strap continuous casting flow distribution device.
Background technology
Strip casting process is one and not only had been related but also distinguishing strip casting process with traditional continuous casting.As shown in Figure 1, it is after molten steel is injected into tundish 3 from ladle, by the mouth of a river 2 molten steel is injected in the current distribution device 1, the perforate of molten steel by the current distribution device bottom will just also be evenly distributed in the molten bath that two water-cooled crystallization rollers 5 and side seal board surround, molten steel solidifies the formation solidified shell gradually on two crystallization roller 5 surfaces, after solidifying fully near two crystallization roller 5 lines of centres, by cooling and rolling after the backwards rotation of two crystallization rollers 5, thus the metal sheet band of formation certain thickness and width.
The twin-roll thin strip continuous casting flow distribution device is in important status in whole strip production, various countries have launched a lot of researchs in this regard, as United States Patent (USP) the 6th, 073,680,5,857,514,6,125,917,6,012, disclosed distributors such as No. 508, it is positioned at the below of tundish.The molten steel that is flowed into by tundish flow in the current distribution device by the discharge orifice of arranging in this distributor.The hanging device that Chinese patent the 01276402.7th, 02283420.6 described current distribution device form is an integral body, the mouth of a river is placed on current distribution device inside, and molten steel directly impacts the two ends at current distribution device, reaches the purpose of cloth stream by the cloth discharge orifice of two ends and both sides.Such current distribution device form has following deficiency:
The streamed impact to liquid level in the molten bath of this cloth is very big, thereby causes the inner liquid fluctuating of current distribution device bigger; Impact to the current distribution device two ends is very big; While current distribution device tapping hole must impact also bigger to the water-cooled roll surface, near the molten steel temperature the side seal board is not high, and easily crust or scull are thicker; Requirement height to side seal board; The quality of edges of band steel is poor; Whole device heat absorption is more serious, causes the inhomogeneous of molten bath internal temperature easily; Whole pool level fluctuation is bigger, and crust easily in the place at the current distribution device inside and outside wall, and crust comes off and easily causes casting process to occur unusually.
Summary of the invention
The purpose of this utility model is to design a kind of thin strap continuous casting flow distribution device, can simplify twin-roll thin strip continuous casting cloth stream, is convenient to lifting and baking, reduces the casting machine height, reduces temperature losses of the process; Evenly, stablize the distribution molten steel and can grasp flexibly with the crystallization control roller in molten bath cloth stream situation and the crystallization roller bath temperature be easy to control, can realize long-time casting.
For achieving the above object, the technical solution of the utility model is,
The thin strap continuous casting flow distribution device, it comprises two submersed nozzles, and submersed nozzle is inverted T-shape, and two submersed nozzles are set up in parallel, and keep the gap between two mouths of a river; Both sides, described submersed nozzle bottom and both ends all have the cloth discharge orifice.
Further, the submersed nozzle of described inverted T-shape comprises the superposed mouth of a river and the current distribution device that is communicated under the mouth of a river; Current distribution device top is semicircle, and the bottom is for semicircle or certain tapering is arranged, and the cloth discharge orifice is offered in the two ends of current distribution device and both sides.
Described cloth discharge orifice and level have downward-sloping angle of a level or level.
Described cloth discharge orifice is radial, and cloth discharge orifice duct internal diameter is inner little, outlet and increases gradually or the homogeneous size.
Described current distribution device both sides respectively have the discharge orifice of arranging, and the shape of cloth discharge orifice is that rectangle or two ends are semicircle shape.
Described cloth discharge orifice is that the center is clockwise or arrangement counterclockwise with the mouth of a river.
In addition, at least one cloth discharge orifice is offered in submersed nozzle described in the utility model or current distribution device bottom.
Insert two submersed nozzles in the molten bath between two rollers, thereby be implemented in and stablize cloth stream in the molten bath between two rollers, between tundish and molten bath, form two independently beam passages, all carrying out the beam flow-control above each mouth of a river and realizing that with this molten metal pool level is controlled between two rollers with a stopper.
The utility model can be realized the even cloth stream of molten steel in the whole molten bath, the molten steel that can effectively reduce liquid fluctuating situation in the molten bath and flow out from the cloth discharge orifice is to the impact of two roller roll surfaces, and can prevent effectively that side seal board place liquid steel temperature is low excessively, cause the cold steel phenomenon of knot, thereby reduce the generation of Cast Strip crackle.Utilize two submersed nozzles can effectively prevent in process of production simultaneously because the reason of load-bearing and impact causes the mouth of a river that the generation of unfavorable factor such as fracture takes place.
The beneficial effects of the utility model:
By adopting the combination of two submersed nozzles, simplified thin strap continuous casting cloth flow structure; Whole mouth of a river device can be fixed fast, and whole and tundish heats together.Tapping hole can be immersed in fully stablizes cloth stream under the bath surface, can reduce the impact of molten steel to two rollers, liquid level and side seal board, prevents that whole pool level fluctuation is excessive; Can prevent to tie cold steel and excessively heat absorption, reduce temperature losses of the process, reduce tapping temperature; Be convenient to level detection mechanism and detect the liquid level variation, can grasp and control the molten steel distribution situation of inside, whole molten bath flexibly; The inner molten steel temperature in molten bath distributes rationally, in the molten bath molten steel fluctuation less, surface temperature and internal temperature difference are less, can realize casting for a long time and replacing fast, thereby have guaranteed the purpose of normally carrying out and producing high-quality band steel of whole casting.
