Abstract
The utility model discloses a slag wall for steel smelting, 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 composed of two upper steel flowing holes and one lower steel flowing hole equipped below the upper steel flowing holes. The three steel flowing holes are disposed into an inverted triangle shape. The hole diameter of the lower steel flowing hole is smaller than that of the two upper steel flowing holes. 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 a 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 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, especially a kind of slag blocking wall that is used for smelting iron and steel.
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 that provide for the deficiency that solves above-mentioned technology a kind of can rationally distribute steel flow to, the slag blocking wall that is used for smelting iron and steel that pushing off the slag is effective.
In order to achieve the above object, the slag blocking wall that is used for smelting iron and steel 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, this steel outlet hole comprises that two are gone up steel outlet hole and are arranged on two following steel outlet holes going up the steel outlet hole below, three steel outlet holes become a del setting, and the aperture of following steel outlet hole is less than the aperture of last steel outlet hole.
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 less than its upper base length.
As preferably, the two sides of described body of wall are stepped, and being provided with of cascaded surface is beneficial to installation, thereby plays good pushing off the slag effect, can save the material of body of wall simultaneously again.
As preferably, 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.

Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Fig. 3 is the side view of the utility model embodiment 2.
Wherein: body of wall 1; Last steel outlet hole 2, following steel outlet hole 3, hanger 4, semi-circular groove 5.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described slag blocking wall that is used for smelting iron and steel of the utility model, it mainly comprises body of wall and steel outlet hole, steel outlet hole is arranged on the body of wall, this steel outlet hole comprises that two are gone up steel outlet hole and are arranged on two following steel outlet holes going up the steel outlet hole below, three steel outlet holes become a del setting, and the aperture of following steel outlet hole is less than the aperture of last steel outlet hole.
The resulting slag blocking wall of the utility model, because steel outlet hole is provided with rationally, can reach reasonable distribution steel flow to, the hot-fluid that rationally distributes, the dead band that can effectively eliminate the 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 that turbulent diffusion from causing surface wave and slag is involved in molten steel inside, pushing off the slag is effective, this slag blocking wall manufacturing process is simple simultaneously, and production cost is lower.
As Fig. 2, shown in Figure 3, the described slag blocking wall that is used for smelting iron and steel of the utility model, it mainly comprises body of wall and steel outlet hole, steel outlet hole is arranged on the body of wall, this steel outlet hole comprises that two are gone up steel outlet hole and are arranged on two following steel outlet holes going up the steel outlet hole below, three steel outlet holes become a del setting, the aperture of following steel outlet hole is less than the aperture of last steel outlet hole, the two sides of body of wall are stepped, body of wall is trapezoidal body of wall, the length of going to the bottom of this body of wall is less than its upper base length, and 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 of the utility model, because steel outlet hole is provided with rationally, can reach reasonable distribution steel flow to, the effect of the hot-fluid that 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.
