Abstract
The invention provides a composite type tundish slag retaining wall. The composite type tundish slag retaining wall comprises a wall body. The wall body is composed of two symmetrical oblique sections and a middle section. Circular-arc filter sections are arranged between the oblique sections and the middle section. An included angle of 120-130 degrees is formed between the two oblique sections. A semicircular convex column is arranged in the middle of the middle section. A steel flow hole is formed in the center of each oblique section and is a conical hole which is upwards oblique by 90-120 degrees. A zirconium conical ring is embedded in each steel flow hole. Molten steel is distributed through the semicircular convex column, and the impact force on the middle section is reduced; and after being distributed, the molten steel then flows to the steel flow holes of the oblique sections, so that the impact force on the steel flow holes is reduced, and the service life is greatly prolonged.
Description
Technical field
The present invention relates to the skimming device in a kind of continuous casting of iron and steel tundish, especially a kind of slag blocking wall.
Background technology
Tundish slag wall, as the important functional refractory material of continuous casting production, has very important effect to the flow Field Design of molten steel in tundish.Flow field determines the flow direction of molten steel, and the floating effect that rational molten steel flows to the interior liquid steel temperature distribution of bag between centering and field trash is obvious.
The general density of field trash in molten steel is more much lower than molten steel, and therefore field trash the most still can float.Owing to the steel outlet hole of tundish slag wall is that molten steel is entered into the passage at the mouth of a river by impact zone, steel outlet hole is washed away the most serious, a lot of slag blocking walls just wash away change greatly at several hours metapores of use, shape becomes very irregular, having had a strong impact on the molten steel flow direction, the floating of field trash is produced a very large impact by this, and along with the change in hole is big, the rate of outflow of molten steel have also been smaller, and in this centering bag, the uniformity of liquid steel temperature also can have a negative impact.
Drawbacks described above haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of service life is long, simple in construction effectively shunts and effectively prevents turbulent flow to molten steel, reduces the compound tundish slag wall of the impact to steel outlet hole.
For realizing the object of the invention, provide techniques below scheme: a kind of compound tundish slag wall, including body of wall, it is characterized in that body of wall is made up of two pieces of symmetrical tilting sections and interlude, it is provided with ffp filter section between tilting section and interlude, between two tilting sections, constitutes the angle of 120 ~ 130 degree, in the middle of interlude, be provided with semicircle projection, steel outlet hole is opened in tilting section center, and steel outlet hole is the taper hole of 90 ~ 120 degree of being inclined upwardly.
As preferably, steel outlet hole is embedded is connected to zirconium matter conical ring.
As preferably, steel outlet hole is gone out side by molten steel inflow lateral flow and is gradually reduced.
As preferably, the thickness of tilting section is 30 ~ 50mm.
As preferably, semicircle convex cylindrical surface interlocking has zirconium matter layer.
As preferably, the ratio of the big footpath of steel outlet hole and path is 3:1.
The method have the benefit that slag blocking wall structure is improved by the present invention, and zirconium matter annulus is set, high abrasion resistance due to zirconium matter annulus, use to 40h all without there is obvious enlargement deformation, well solving the expansion problem of tundish slag wall steel outlet hole, service life is long, simple in construction, molten steel effectively shunts and effectively prevents turbulent flow, reduces the impact to steel outlet hole.
