Abstract
The invention provides a rotary outlet type submerged nozzle for continuous casting, which comprises a submerged nozzle body and a water inlet and a water outlet which are mutually orthogonal, wherein the bottom surface of the submerged nozzle is provided with at least two diversion ports, and the diversion ports are arranged in a spiral way. The invention has the main advantage that the rotary outlet type submerged nozzle for continuous casting can enable the temperature of molten steel to be more uniform, better control the dissolving of crystallizer protecting slag, reduce the generation possibility of eddy current, improve the quality of molten steel, replace the electromagnetic stirring effect to a certain extent and save the energy.
Description
Technical field
The present invention relates to a kind of continuous casting rotary outlet submersed nozzle.
Background technology
Continuous casting is the important production process of modern steel metallurgy, and the effect of submersed nozzle is that metallic solution is incorporated into the crystallizer from tundish.Submersed nozzle is steel mill's continuous casting requisite parts of equipment, and it is except having the steel of guiding stream, and main is control and improves the flow regime of steel stream in crystallizer, and the interior liquid level of maintenance crystallizer is stable.
As shown in Figure 1, general submersed nozzle for routine, the inwall of its submersed nozzle body 1 is through-type, molten steel enters from water inlet 11, by through-type passage from flowing out with the vertically disposed delivery ports 12 of water inlet 11, the flow-guiding mouth that the bottom surface 3 of delivery port 12 is offered is straight flow-guiding mouth 31, and the generation of eddy current is arranged when causing molten steel to enter mould, influences the quality of molten steel.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of continuous casting rotary outlet submersed nozzle is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of continuous casting rotary outlet submersed nozzle comprises submersed nozzle body, mutual vertically disposed water inlet and delivery port, is provided with two flow-guiding mouths on the bottom surface of wherein said submersed nozzle at least, and described flow-guiding mouth is the spiral setting.
Further, above-described continuous casting rotary outlet submersed nozzle, relative formation one up/down steps in wherein said flow-guiding mouth bottom surface with delivery port bottom surface, bottom center position.
Beneficial effect of the present invention is mainly reflected in: continuous casting can make the more uniform temperature of molten steel with the rotary outlet submersed nozzle; the better dissolving of crystallization control device covering slag reduces the generation of eddy current, improves the quality of molten steel; and can replace the use of electromagnetic agitation to a certain extent, save the energy.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: common submersed nozzle generalized section of the prior art.
Fig. 2: common submersed nozzle of the prior art is along the cutaway view of A-A.
Fig. 3: submersed nozzle of the present invention is along the cutaway view of A-A.
Wherein:
1 submersed nozzle body, 11 water inlets, 12 delivery ports
3 bottom surfaces, 31 straight flow-guiding mouth 32 flow-guiding mouths
4 steps
The specific embodiment
The present invention has disclosed a kind of continuous casting rotary outlet submersed nozzle, as shown in Figure 2, comprises submersed nozzle body 1, mutual vertically disposed water inlet 11 and delivery port 12, is provided with the flow-guiding mouth 32 that two spirals are provided with on the bottom surface 3 of submersed nozzle at least.Simultaneously, form a up/down steps 4 in flow-guiding mouth 32 bottom surfaces and delivery port bottom surface, 3 center, bottom surface, step 4 has played the effect of buffering when molten steel flows out.
The present invention compared with prior art has the following advantages: continuous casting can make the more uniform temperature of molten steel with the rotary outlet submersed nozzle; the better dissolving of crystallization control device covering slag; because flow-guiding mouth 32 adopts the spiral setting; reduce the generation of eddy current; improve the quality of molten steel; and can replace the use of electromagnetic agitation to a certain extent, save the energy.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
