Abstract
The invention provides a submersed nozzle for a thin slab, which comprises an inlet, an inner cavity, stream guidance bosses and a triangular dividing body, wherein the stream guidance bosses are symmetrically arranged on both sides of a central axis of the submersed nozzle, the triangular dividing body is arranged in the middle of an outlet to divide the outlet into two outflow ports. The inner cavity is a combined surface consisting of a group of planes. Edges are arranged between every two adjacent planes so that the planes are not coplanar with each other. The invention has the advantages that the design of the submersed nozzle for the thin slab ensures that steel flows inside the nozzle and at the outlet are more stable and the molten steel can flow reasonably in the crystallizer to reduce unstable state of a molten steel liquid level, thereby improving the quality of the thin slab and prolonging the service life of the submersed nozzle.
Description
Technical field
The present invention relates to a kind of thin stock plate submersed nozzle.
Background technology
The thin stock plate continuous casting is the comparatively novel technology of steel casting, compare with common continuous casting, the characteristics of thin stock plate continuous casting are that the crystallization space is little, pulling rate is fast, the molten steel surface wave takes place easily roll up slag greatly, accidents such as the unreasonable generation bleedout of Flow Field Distribution, thereby used submersed nozzle all had higher requirement from the structure to the material.Structurally because crystallizer is narrow, the size-constrained system in the mouth of a river can only be made pancake, the structure of its inner chamber is wanted can guarantee the flow of molten steel and a rational flow field is arranged in crystallizer, mouth of a river wall thickness is limited, and its slag line material should have good corrosion resistance, to guarantee the long as far as possible continuous casting time.
Existing submersed nozzle as shown in Figure 1, molten steel flows into from import 1, flows in smooth inner lumen 2, because submersed nozzle has been symmetrical arranged water conservancy diversion boss 3 at inner chamber 2 along the central axis position, molten steel is met water conservancy diversion boss 3 and is formed shunting, divides the outlet 4 at fluid 31 places to flow out by triangle is set at last.Though this structure has good practical function,, still can not guarantee the stability that steel flows, can not well overcome the liquid fluctuating problem.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of thin stock plate submersed nozzle is provided.
Purpose of the present invention is achieved through the following technical solutions:
Thin stock plate submersed nozzle, comprise import, inner chamber, be symmetricly set on the water conservancy diversion boss of submersed nozzle central axis both sides, and be arranged at the outlet centre position divide fluid with the triangle that outlet is divided into two flow exports, described inner chamber is the combinatorial surface that one group of plane is formed, between described each adjacent planar seamed edge is arranged, make between the described plane mutually not coplane.
Beneficial effect of the present invention is mainly reflected in: the design of this thin stock plate submersed nozzle makes steel stream in inside, the mouth of a river and exit better stability be arranged, make molten steel in crystallizer, reasonably to flow, reduce the labile state of liquid steel level, thereby improved the quality of thin stock plate, prolonged the life-span of submersed nozzle.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: thin stock plate submersed nozzle generalized section of the prior art.
Fig. 2: thin stock plate submersed nozzle generalized section of the present invention.
Wherein:
1 import, 2 inner chambers, 21 planes
3 water conservancy diversion boss, 31 triangles divide fluid 4 outlets
The specific embodiment
The present invention has disclosed a kind of thin stock plate submersed nozzle, as shown in Figure 2, comprise import 1, inner chamber 2, be symmetricly set on the water conservancy diversion boss 3 of submersed nozzle central axis both sides, and be arranged at outlet 4 centre positions and will export 4 triangles that are divided into two flow exports and divide fluid 31, wherein said inner chamber 2 is the combinatorial surface that one group of plane 21 is formed, and forms the not coplane body with many seamed edges between the described combinatorial surface, and promptly similar adamantine shape is formed, formed to combinatorial surface by the plurality of sections plane.
After molten steel enters from import 1,,, from two outlets 4, flow out after dividing the shunting of fluid 31 by triangle again through the water conservancy diversion of water conservancy diversion boss 3 by the interior guide face 21 of similar diamond shape.
The present invention compared with prior art has the following advantages: the interior guide face 21 similar adamantine designs of this thin stock plate submersed nozzle, guide face 21 has some seamed edges in making, with level and smooth in the prior art and decide inner chamber 2 and compare, have a plurality of planes, make steel stream better stability be arranged, make molten steel in crystallizer, reasonably to flow, reduce the labile state of liquid steel level in inside, the mouth of a river and exit, thereby improved the quality of thin stock plate, prolonged the life-span of submersed nozzle.
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.
Claims (1)
