Definitions
- the invention relates to a float, the float and a Float body has fixable guide rod.
- floats are well known in the art and are, for example used to retain the slag in a converter.
- floats consist of a hemisphere made of concrete with a defined Density and a built-in guide rod.
- the swimmers swim against End of a converter tapping between steel and slag and prevent that Slag flows out of the converter.
- the guide rod is already in the Float body installed if the float is supplied by the manufacturer. Out However, for space or transportation reasons, it is sometimes preferred if the swimmer is supplied in two parts by the manufacturer. The assembly is then at the customer performed.
- connection options for suggested the float body and the guide rods, but all very are complex and also special tools, mortar or other handling objects require.
- the present invention is therefore based on the object of providing a float its assembly without any aids to simple and inexpensive Way can be accomplished.
- this object is achieved in that a spring washer in the Float body is incorporated, which after assembly the guide rod encloses and with this a non-dissolving under operating conditions Connection comes in.
- the float body needs only via the guide rod to be put over or the guide rod pushed into the float body to become, without the need for additional tools. Will the guide rod pushed in the direction of insertion through the spring washer into the float, so this is clamped by the spring washer and can no longer come out of the float to be pulled.
- the spring washer has a through opening provided with lamellae on. The through opening of the spring washer has a smaller diameter than the guide bar on.
- the guide rod consists of an elongated metallic part, a part of its length made of a fire-resistant material has, wherein the spring washer after assembly with the elongated metallic Part of the connection that does not come loose under operating conditions. By the metallic part of the jacket is protected from the melt.
- the Float body through a passage through which the guide rod is pushed and into which the spring washer is incorporated, a first part of the through opening, which is adjacent to the spring washer, has a diameter which in corresponds essentially to the diameter of the jacket. At least encloses part of the first through opening the jacket. Because the coat in the first Part of the through hole protrudes, the metallic part of the guide rod protected from the slag.
- a second part of the through opening, that adjoins the spring washer from the opposite side one Have diameter that is essentially the diameter of the elongated metallic Partially corresponds. This results in an exact and form-fitting connection between the float body and the guide rod.
- the float body is advantageously hemispherical.
- FIG. 4 shows a preferred embodiment of the present invention.
- the assembled float shown in FIG. 4 consists of the one shown in FIG. 1 shown guide rod 3, 4 and the float body shown in Fig. 2 1.
- the Float body 1 is essentially hemispherical and has a center a through opening 7a, 7b.
- the float has a certain density and so swims towards the end of a converter tapping between steel and slag and thus prevents slag from flowing out of the converter.
- the guide rod consists of a metallic part 3, which has a part its length has a protective jacket 4, which is preferably made of a refractory Material exists.
- the through opening of the float body 1 from two parts 7a and 7b, each bordering on the spring washer 2 and through these are separate.
- the first part 7a of the through opening 7 has a diameter b, which essentially corresponds to the diameter a of the jacket of the guide rod 4 corresponds.
- the second part 7b of the through opening 7 has a diameter c which is essentially the diameter d of the unclad metallic part 3 corresponds.
- the first part 7a of the through opening 7 is via the opening 8 of the spring washer 2 connected to the second part of the through opening 7b.
- the diameter the opening 8 of the spring washer 2 is smaller than the diameter b of the through opening 7a and smaller than the diameter d of the metallic part 3.
- FIG. 5a a preferred embodiment of a spring washer 2 is shown, which is shown in FIG the float body 1 is installed.
- the spring washer 2 is made of spring steel and, as can be seen in Fig. 5b, deformed curved to give a better spring effect achieve.
- the spring washer 2 has a plurality of radially inwardly directed Slats 6, which serve that the spring washer and the guide rod a form a solid connection with each other.
- the jacket 4 protrudes only a little into the first part of the through opening 7a.
- the arrangement of the passage opening parts 7a, 7b of the float body 1, the Size and the arrangement of the spring washer are of course not on this Embodiment limited.
- the spring washer can also be used at the beginning or be arranged at the end of the through opening of the float body 1.
