Abstract
The utility model discloses a slag wall inside a tundish, which mainly comprises a wall body and steel flowing holes. The steel flowing holes are provided in the wall body. The utility model is characterized in that the steel flowing holes are equipped in the wall body in three rows, namely an upper row, a middle row and a lower row. The longitudinal projections of the steel flowing holes in the upper row and the steel flowing holes in the lower row are located between every two adjacent steel flowing holes in the middle row. The utility model can achieve a reasonable distribution of molten steel flow directions and a reasonable hot-fluid distribution, save materials, effectively eliminate the dead zone on the bottom area of the tundish and improve molten steel flowing tracks due to the reasonable installation of the steel flowing holes. Furthermore, the utility model can confine the intense eddy currents generated by steel ladle stream injection impacts in a local area and prevent the turbulence from spreading in case the surface is fluctuated and then the slag is involved in the molten steel. The slag wall in the utility model has the advantages of good slag stopping effects, simple manufacturing technology and relatively low producing cost.
Description
Technical field
The utility model relates to the skimming device in a kind of smelting iron and steel stove tundish, the slag blocking wall in especially a kind of tundish.
Background technology
In steel smelting procedure, because MOLTEN STEEL FLOW is uneven in the tundish, some places are fast, and some places are slow, and especially there is sluggish molten steel stagnant wake in the tundish bottom section, makes the inclusion floating difficulty.In order fully to effectively utilize the tundish volume, promote inclusion floating, people are provided with slag blocking wall usually in tundish, traditional slag blocking wall is generally the body of wall on plane, are not provided with or only are provided with a steel outlet hole on the body of wall, it is unreasonable that steel outlet hole is provided with, in actual use, the steel flow that can't rationally distribute to, can not effectively improve the molten steel flow track, make turbulent diffusion cause surface wave and slag is involved in molten steel inside easily, be difficult to satisfy the production demand.
Summary of the invention
The purpose of this utility model is provide for the deficiency that solves above-mentioned technology a kind of slag blocking wall of steel flow in the effective a kind of tundish of, pushing off the slag that can rationally distribute.
In order to achieve the above object, the interior slag blocking wall of a kind of tundish that the utility model is designed, it mainly comprises body of wall and steel outlet hole, steel outlet hole is arranged on the body of wall, described steel outlet hole branch upper, middle and lower triplex row is arranged on the body of wall, and described longitudinal projection of going up steel outlet hole and following steel outlet hole is in two between the steel outlet hole.
As preferably, described steel outlet hole is positioned at the middle and lower part of body of wall.
As preferably, described steel outlet hole quantity is ten, is followed successively by three, four, three from top to bottom, distribution steel flow that can be effective and reasonable to.
As preferably, described body of wall is trapezoidal body of wall, and the length of going to the bottom of this body of wall is greater than its upper base length, and being provided with of trapezoidal body of wall is beneficial to installation, thereby plays good pushing off the slag effect, can save the material of body of wall simultaneously again.
As preferably, it is characterized in that described body of wall upper surface is provided with two semi-circular groove, is respectively equipped with hanger in semi-circular groove.
The resulting slag blocking wall that is used for smelting iron and steel of the utility model, because steel outlet hole is provided with rationally, can reach reasonable distribution steel flow to, hot-fluid rationally distributes, save material, can effectively eliminate the dead band of tundish bottom section, improve the MOLTEN STEEL FLOW track, the ladle beam can be impacted caused strong eddy current and be limited in regional area, prevent turbulent diffusion from causing surface wave and slag is involved in molten steel inside, pushing off the slag is effective, and this slag blocking wall manufacturing process is simple simultaneously, and production cost is lower.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Wherein: body of wall 1, last steel outlet hole 2, middle steel outlet hole 3, following steel outlet hole 4, hanger 5, semi-circular groove 6.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, slag blocking wall in the described a kind of tundish of the utility model, it mainly comprises body of wall and steel outlet hole, steel outlet hole is arranged on the body of wall, described steel outlet hole branch upper, middle and lower triplex row is arranged on the body of wall, and described longitudinal projection of going up steel outlet hole and following steel outlet hole is in two between the steel outlet hole.
The resulting slag blocking wall that is used for smelting iron and steel of the utility model, because steel outlet hole is provided with rationally, can reach reasonable distribution steel flow to, rationally the distribution hot-fluid is saved material, the dead band that can effectively eliminate the tundish bottom section, improve the MOLTEN STEEL FLOW track, pushing off the slag is effective, and this slag blocking wall manufacturing process is simple simultaneously, and production cost is lower.
As shown in Figure 2, slag blocking wall in the described a kind of tundish of the utility model, it mainly comprises body of wall and steel outlet hole, steel outlet hole is arranged on the body of wall, on described steel outlet hole divides, in, following triplex row is arranged on the body of wall, the longitudinal projection of last steel outlet hole and following steel outlet hole is in two between the steel outlet hole, this steel outlet hole is positioned at the middle and lower part of body of wall, quantity is ten, be followed successively by three from top to bottom, four, three, described body of wall is trapezoidal body of wall, and the length of going to the bottom of this body of wall is greater than its upper base length, the body of wall upper surface is provided with two semi-circular groove, is respectively equipped with hanger in semi-circular groove.
The resulting slag blocking wall that is used for smelting iron and steel of the utility model, because steel outlet hole is provided with rationally, can reach reasonable distribution steel flow to, reasonable distribution hot-fluid, being provided with of trapezoidal body of wall is beneficial to installation, thereby plays good pushing off the slag effect, can save the material of body of wall simultaneously again, can effectively eliminate the dead band of tundish bottom section, improve the MOLTEN STEEL FLOW track.
