Description
Technical field
The utility model belongs to the technical field that metallurgical industry is produced, and relates to steel-smelting production process equipment, and more particularly, the utility model relates to a kind of adding apparatus of ladle draining sand.
Background technology
Ladle draining sand adds after the water inlet, contacts with molten steel, forms fine and close sinter layer rapidly at the steel sand interface, and after opened at the mouth of a river, sinter layer was broken by ferrostatic pressure, reaches ladle from the effect of opening.
The mode that adds drainage sand at present has throw-in type and catheter type, and wherein conduit adds sand and is divided into two kinds again, and promptly tilting adds and rectilinear adding.
It is that drainage sand is thrown into position, the ladle bottom mouth of a river with the artificial method that drops into that throw-in type adds sand; It is to lift ladle with overhead traveling crane that conduit tilts to add the sand mode, makes ladle be 30 ° of inclinations, and the conduit oblique cutting is irritated the sand operation to the mouth of a river; Comparatively speaking, the method that vertical conduit adds drainage sand makes drainage sand density even, and the sinter layer shape intact more helps ladle from opening.
But vertical conduit adds sand and has following problem, at first is that catheter tip is directly aimed at the mouth of a river; Added drainage sand surface and formed not mild arch, perhaps the conduit lower end is fixing, but when pulling up conduit; Can destroy drainage sand surface configuration, this can cause that all big bag self-opening rate descends.
The utility model content
The utility model at first provides a kind of adding apparatus of ladle draining sand, its objective is improve ladle draining sand add the sand effect.
To achieve these goals, the technical scheme taked of the utility model is:
The adding apparatus of the ladle draining sand that the utility model provided comprises conduit, and described conduit vertically is provided with, and the upper end of described conduit is established and added the sand mouth, and conduit bottom support is established in the lower end of described conduit.
Described conduit bottom support is three or the three above outwards legs of fork.
The height of described conduit bottom support in the vertical direction is 100mm.
The described upper edge hole that adds the sand mouth is connected with steel cable, and described steel cable is on fixed pulley; The other end of described steel cable is connected with weight, makes described steel cable two ends balance.
Described steel cable is connected with the described sand mouth that adds through the fork hawser of the equal length more than three or three, makes steel cable under the state of lifting, and the projection of its vertical direction is positioned at the described center that adds the sand mouth.
The utility model also provides the drainage sand adding method that adding apparatus adopted of above-mentioned ladle draining sand in order to realize the goal of the invention identical with technique scheme, and its technical scheme is:
Before steel-supplying position, set up a platform, completion adds the sand operation on platform;
The drainage sand adding method that the adding apparatus of described drainage sand adopts is:
With the ladle handling of handling clean water ports and be located on the buggy ladle;
Buggy ladle leaves to said platform below;
Upwards mention said weight, said conduit is descended and the aligning mouth of a river, the lower end of said catheter tip support supports to around the mouth of a river, begins to add the sand operation;
Add sand to drainage sand and form circular convexity, vertically mention said conduit, under the acting in conjunction of weight, conduit moves up to certain altitude to be stopped;
Add sand and accomplish, the ladle that adds sand is transported to the tapping station.
The utility model adopts technique scheme, solved and thrown that sand is inaccurate, arch not just, the problem of density irregularity; Increase support at catheter tip, make catheter tip be fixed in 100mm place, top, the mouth of a river, drainage sand falls naturally, forms mild arch; The conduit upper end increases fixed pulley, links to each other with terminal counterweight with steel wire rope, makes the conduit vertical lift, avoids catheter tip to destroy drainage sand profile, has guaranteed to add the stability of sand operation.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure briefly explains:
Fig. 1 is the guide-tube structure sketch map of the utility model;
Fig. 2 vertically adds sand mode sketch map for the conduit of the utility model.
Be labeled as among the figure:
1, conduit, 2, conduit bottom support, 3, add the sand mouth, 4, steel cable, 5, fixed pulley, 6, weight.
The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Structure like the expressed the utility model of Fig. 1, Fig. 2 is a kind of adding apparatus of ladle draining sand, comprises conduit 1, and described conduit 1 vertically is provided with, and the upper end of described conduit 1 is established and added sand mouth 3.The utility model improved be the filling sand mode that vertically adds sand.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize improving the goal of the invention that adds the sand effect of ladle draining sand, the technical scheme that the utility model is taked is:
Like Fig. 1, shown in Figure 2, the adding apparatus of the ladle draining sand that the utility model provided, conduit bottom support 2 is established in the lower end of described conduit 1.
Described conduit bottom support 2 is three or the three above outwards legs of fork.Realized the stationarity that supports.
Its advantage is:
Add that the sand mode adopts vertical adding and with catheter positioning and fixing mode, solved and thrown that sand is inaccurate, arch not just, the problem of density irregularity; At the conduit 1 terminal support that increases, make catheter tip be fixed in top, the mouth of a river, drainage sand falls naturally, forms mild arch.Its switch is similar in appearance to the steamed bun of a circle, and its effect is ideal.
