Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 3, the slag grate for ferroalloy stokehole casting includes a transition tank 1, a liquid slag tank 2, an iron flowing tank 3, an iron sinking tank 4, and a grate 5, wherein the transition tank 1 is abutted to the liquid slag tank 2, and the top surface of the liquid slag tank 2 is lower than the top surface of the transition tank 1, so that when molten iron enters the transition tank 1 from a submerged arc furnace 9, slag in the molten iron floats upwards and flows to the liquid slag tank 2.

The iron flowing pool 3 is symmetrically arranged on two sides of the transition pool 1, so that molten iron can be shunted, one-side maintenance is facilitated, the grate 5 is arranged at the butt part of the iron flowing pool, a grate channel 8 is arranged below the grate 5, so that dregs can not pass through, a slag stopping function can be realized, and the molten iron flows into the iron flowing pool 3 through the grate channel 8.

The iron sinking pool 4 and the iron flowing pool 3 are arranged in parallel and share a butt joint surface, and an iron sinking discharge opening 6 is arranged below the butt joint surface.

And a casting iron port 7 is arranged below one side of the casting iron pool 3 and is connected with the layer casting pool 10, so that molten iron in the casting iron pool 3 can be drained in time, and the continuous work of the slag grate is realized.

The liquid slag pool 2 is made of cast iron materials and is connected with the water tank 11, and water flushing of slag can be achieved.

The transition tank 1, the iron flowing tank 3 and the iron sinking tank 4 are built by molding sand, and are high-temperature resistant and not easy to deform.

The grate 5 is made of carbon bricks and has high temperature resistance and good slag resistance.

The high-temperature resistant plug is arranged at the position of the iron sinking discharging opening 6, when a furnace of molten iron is discharged, the plug is opened, and the residual molten iron is discharged to the iron sinking tank 4 through the iron sinking discharging opening 6 for recycling, so that the clogging of the grate channel 8 can not be caused.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
