Abstract
The invention relates to a combined detachable embedded ladle edge, which comprises six connecting plates, rib plates and refractory materials, wherein the rib plates are vertically arranged on the inner sides of the connecting plates, the six connecting plates are uniformly arranged on the inner sides of ladle openings, the connecting plates are fixedly connected with the inner walls of the ladle openings through bolts, the rib plates are perpendicular to the upper edge of the ladle openings, the refractory materials are poured between every two adjacent rib plates to form the ladle edges, and refractory material bricks are built below the ladle edges on the inner sides of the ladle openings. The long-term verification proves that the service life of the ladle edge is greatly prolonged and is 2-3 times of that of the welding type ladle edge, the ladle edge is tightly connected with the inner wall of the ladle opening of the ladle through the bolt, the replacement is simple, the time and the labor are saved, the ladle edge of the position which is easy to damage can be replaced independently, and the replacement time of each time is about 1/3 of the welding type.
Description
Technical Field
The invention relates to the technical field of ferrous metallurgy, in particular to a combined detachable embedded ladle edge.
Background
At present, the ladle edges of various steel mills are generally welded, and after the ladle edges are used for a certain time, the ladle edges are gradually warped and deformed along with the thermal expansion of ladle lining refractory materials. After the deformation reaches a certain degree, the wrapping edge can not fix the refractory material any more, and the service life of the refractory material is greatly influenced. Meanwhile, the electrode position in the LF process for steel making has great damage to the wrapping edge, a new wrapping edge is always on line, the wrapping edge at the electrode position is melted, and the situation that all the wrapping edges are replaced again is forced. In addition, the steel ladle capping energy-saving heat preservation technology is commonly adopted in various large steel plants at present, the upwarping of the ladle edge can cause great influence on the elevation of the ladle cap, and the ladle cap cannot be capped normally. The welding type package edge is required to be completely cut off and abandoned when replaced, and then the new package edge is welded again, so that time and labor are wasted, and the cost is high.
Fig. 1 shows a welded ladle edge in the prior art, which is structurally characterized in that a circle of welded ladle edge is welded on the outer side surface of the inner wall of a ladle opening in a manner of clinging to the edge of the ladle opening, and grout is filled between the welded ladle edge and a refractory brick to form the ladle edge.
The existing ladle edge is deformed or melted to a certain degree and is integrally replaced, rib plates are welded on the inner side of the ladle wall of a ladle opening in some steel mills, the old ladle edge is replaced after a refractory material is built, but the welding time is cut again after the rib plates are melted and deformed, so that the steel ladle repairing time is influenced.
Disclosure of Invention
In order to overcome the defects, the invention aims to provide a combined detachable embedded type steel ladle edge.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides an embedded ladle package edge can be dismantled in combination, includes six connecting plates, gusset, refractory material, the inboard of connecting plate is equipped with the gusset perpendicularly, six the even inboard of installing at ladle package mouth of connecting plate, connecting plate and ladle package mouth inner wall pass through bolt-up connection, make gusset perpendicular to ladle package mouth's top edge, and the pouring has refractory material between two adjacent gussets, forms a package edge, and ladle package mouth inboard is located the below on package edge and builds refractory material brick by laying bricks or stones.
Specifically, the refractory material is poured between rib plates of the connecting plate through a pouring process.
The invention has the following beneficial effects: the long-term verification proves that the service life of the ladle edge is greatly prolonged and is 2-3 times of that of the welding type ladle edge, the ladle edge is tightly connected with the inner wall of the ladle opening of the ladle through the bolt, the replacement is simple, the time and the labor are saved, the ladle edge of the position which is easy to damage can be replaced independently, and the replacement time of each time is about 1/3 of the welding type.

In the figure, 1 steel ladle opening, 2 welding ladle edge, 3 grouting material, 4 refractory brick, 5 refractory material, 6 connecting plate and 61 rib plate.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
According to the combined detachable embedded ladle edge shown in the figures 2 and 3, the combined detachable embedded ladle edge comprises six connecting plates 6, rib plates 61 and refractory materials 5, wherein the rib plates 61 are vertically arranged on the inner sides of the connecting plates 6, the six connecting plates 61 are uniformly installed on the inner sides of a ladle opening 1, the connecting plates 6 are fixedly connected with the inner wall of the ladle opening 1 through bolts 7, the rib plates 61 are perpendicular to the upper edge of the ladle opening 1, the refractory materials 5 are poured between every two adjacent rib plates 61 to form a ladle edge, and refractory material bricks 4 are built below the ladle edge on the inner side of the ladle opening 1.
Specifically, the refractory 5 is poured between two adjacent rib plates 61 by a pouring process.
The present invention is not limited to the above embodiments, and any structural changes made under the teaching of the present invention shall fall within the protection scope of the present invention, which is similar or similar to the technical solutions of the present invention.
The techniques, shapes, and configurations not described in detail in the present invention are all known techniques.
