In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the connection may be direct or indirect via an intermediate medium, and may be a communication between the two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to the figures 1-3, the invention relates to a ladle molten steel rapid ladle slag device, which is provided with a ladle slag barrel 2, wherein the upper surface and the lower surface of the ladle slag barrel are open, the symmetrical positions of the side wall of the upper end of the ladle slag barrel are provided with hoisting ear plates 1, a ladle slag tray 5 is arranged in the ladle slag barrel, the ladle slag tray divides the inner part of the ladle slag barrel into an upper part and a lower part, the height of the upper bottom surface of the ladle slag tray is lower than that of the upper end surface of the ladle slag barrel, a plurality of slag overflow hole pipes 6 are inserted in the ladle slag tray, the upper end openings of the slag overflow hole pipes are higher than that of the ladle slag tray, and the lower end openings of the slag overflow hole pipes penetrate through the lower bottom surface of the ladle slag tray; and a plurality of small slag-absorbing steel columns 3 are also arranged on the lower bottom surface of the ladle slag tray downwards.

Furthermore, in this embodiment, the slag overflow hole pipes are radially distributed from the center to the periphery on the ladle slag tray, and the slag overflow hole pipes on each circle are uniformly distributed at intervals.

Further, in the embodiment, the height of the lower bottom surface of the ladle slag tray is higher than that of the lower end surface of the ladle slag cylinder.

Furthermore, in this embodiment, the lower end of the small slag-absorbing steel column extends out of the port of the lower bottom surface of the ladle slag tray, and the small slag-absorbing steel column is made of a steel bar column with rough patterns 4 on the outer wall.

The hot molten steel density in the actual ladle was 7.0 x 10³About, and the density of cold steel is 7.85 x 10³Left and rightThe density of the scum is 2-3 x 10³Left and right, therefore when using, the whole ladle slag cylinder of the invention is hoisted and put into the molten steel of the ladle for several times, because the density of the scum is small, the ladle slag cylinder and the ladle slag tray of the invention are made of cold steel and have relatively large density, when it sinks into the hot molten steel, but will not sink too much, sink under the scum, the scum will float out from the hole tube of the slag overflow, and spill out from the upper port of the hole tube of the slag overflow and fall on the ladle slag tray, can come out the dreg basically once when the scum quantity is small, repeat the operation two or three times when the quantity is large and basically finish the clearing.

The coarse patterns are arranged on the small slag-absorbing steel columns at the bottom of the ladle slag tray, so that the contact area between equipment and steel ladle molten steel during ladle slag can be increased, and slag can be adsorbed and brought out from the steel ladle slag-absorbing steel columns, and the cleaning effect is improved.

The ladybug slag tray and the slag overflow hole pipe can block a part of holes after being used for many times, the equipment can be directly put into cold water when the ladybug slag tray and the slag overflow hole pipe are hot, and slag can easily fall into the water before solidification, so that the purpose of cleaning the hole pipe is achieved.

The invention greatly improves the slag impurity cleaning efficiency of molten steel in the whole ladle by designing a brand-new ladle slag cleaning tool to replace the original ladle slag cleaning mode, the structural design of the whole equipment is very simple, the equipment is safer and more efficient compared with the traditional slag cleaning treatment operation, the actual use effect is very obvious, the manufacturing cost of the equipment is low, and the economic benefit is high.
