Abstract
The utility model provides a submerged nozzle for continuous casting to solve the problem (of other submerged nozzles) of component segregation of molten steel caused by deficiency of radial stirring to the molten steel flowing out from a lateral hole. The submerged nozzle comprises a bowl part, a body, an inner hole, and at least two uniformly-arranged lateral holes, etc.; wherein the lateral holes form an angle of alpha with circumferential direction of the body. With the improved submerged nozzle, radial rotary stirring is generated under action of centrifugal force when the molten steel flows out of the lateral holes, so magnetic stirring system of a crystallizer can be replaced, component segregation of the molten steel is avoided, quality of steel blank is improved, and the input cost of manufacturing device of manufacturer is reduced effectively.
Description
Technical field
The utility model relates to a kind of immersion water gap for continuously casting, specifically is a kind of submersed nozzle with rotation stirring action.
Background technology
Submersed nozzle is steel mill's continuous casting must obligato parts with equipment, and it is except having guiding steel stream, and main is control and improves the flow regime of steel stream in crystallizer.Used submersed nozzle in the prior art, side opening all is a straight hole, after molten steel flows out from side opening like this, can only form the impact that the footpath makes progress to the molten steel in the crystallizer in moment, flow downward by the gravity effect then, the stirring on forming vertically to the molten steel in the crystallizer, like this, molten steel flows downward in the process owing to lack the stirring that the footpath makes progress, and occurs the molten steel composition segregation easily, influences the quality of continuous casting billet.For preventing that component segregation from appearring in molten steel, need increase electromagnetic stirring system to crystallizer, thereby produce stirring transversely.So also certainly will increase the equipment input of manufacturer.
Summary of the invention
The utility model lacks the problem that easily produces the molten steel composition segregation that radially stirs for solving above-mentioned submersed nozzle contralateral exposure outflow molten steel, a kind of improved submersed nozzle is provided, this submersed nozzle comprises a bowl portion, body, endoporus and uniform side opening etc. more than at least two, and side opening and body have an angle α at circumferencial direction.
In the utility model, can also have following technical characterictic: 20≤α≤45.
In the utility model, can also have following technical characterictic: the utility model side opening can also have an angle β in the horizontal direction with body, and 15≤β≤30.
The best inwall of side opening in the utility model has a line or face and endoporus tangent.
Use this improved submersed nozzle, molten steel when side opening flows out because action of centrifugal force will produce the rotation stirring that the footpath makes progress, can substitute the crystallizer electromagnetic stirring system like this, avoid the molten steel composition segregation, help the raising of billet quality, and can effectively reduce manufacturer production equipment input cost.
