The invention relates to a loading basket for loading an electric arc furnace with a Scrap block, consisting of a support ring attached to a main suspension rope, from which several chains hang down, which are releasably connected at their lower ends.

Such a loading basket is known from DT-PS 35 453 The releasable connection of the individual Chains are made by an easily combustible or easily meltable fastening means that through the heat of the oven burns or melts making it necessary to remove the fastener after each To replace loading and occurs with the loading itself the significant disadvantage that the release the scrap load takes place after a more or less long exposure time to the heat of the furnace and is not well defined or precisely controllable

From CH-PS 2 84 505 it is known depending To provide carrying ropes of a loading basket at their lower ends with rings through which a closing cable is threaded and locked at its ends by a detachable plug connection. Draft The plug-in pin of the connector can be loosened on a release rope, so that the cohesion the lower locking rings is lifted and the lower end of the loading basket is under the weight of the scrap block expands and releases it. However, the threading of the closing rope into the rings is quite tedious and time consuming.

The object of the invention is to create a loading basket of the type indicated at the beginning, which does not have any locking parts lost when charging an electric arc furnace but still quickly locked with a simple structure and by arbitrary control from the outside can be operated.

According to the invention this object is achieved in that the releasable connection consists of one of several Individual links existing bottom-end chain is formed, the individual links releasable from the outside Connecting pins are connected.

Since the individual elements without any Einfädelungsvorgänge need only be connected to one another or to the adjacent chain respectively, ^We can ^en The invention is described below with reference to a _Z e ^ haen2h shown near Ausführungsbe.sp.eles

The bottom side is releasably connected to one another

The connecting link 9 and nut .hm Z connecting pin 5 is connected via an associated auxiliary chain 4.14 in the in FIG. 1 illustrated We.- "mii learn all connecting links» «££ * ·" ■ connection pin 5 common pull rope 13 connected.

The following is the mode of operation of the inventive JSe.iLchungskorbes explained Um m.t de, *, Be «Loading basket a block of scrap 7 into an electric high-speed furnace to charge, ^. ^ SSJ ^ basket raised by means of a hoist over the scrap block 7, in such a way that the hanging chains 3 You surround the sides of the scrap block 7: then the individual links of the bottom end chain 8 connected to one another by the connecting links whereupon the scrap eye 7 on the support ring »hanging from the chains 3 and the bottom chain 8 under · handles is introduced into the electric arc furnace. When the loading basket is raised, the pull rope is activated ? 3 loose. Since the hanging scrap block 7 closes the bottom chain 8 in the direction of the arrows (see Fig. 3) the connecting pin 5 cannot stretch out of the

Slide out the pin bore 10. When the scrap block 7 reaches the furnace floor, the main support set 6 becomes loose and the pull rope 13 is tightened. Through this the connecting pins S are pulled out of the pin bores 10, so that the chain end links 11 and 12 can be detached from each other. In this way, the individual links of the bottom end chain 8 separated from each other and the lower ends of the chains 3 released, whereupon the chains 3 and the single handle of the bottom end chain 8 at Lifting the support ring 1 together with this, leaving the scrap block 7 on the furnace floor and the end of the input process can be withdrawn from the oven. As a result of the construction and

the arrangement of the loading basket according to the invention, the loading process can be safe and easy be performed. This will reduce the labor time for inputting the block of scrap into an electric arc furnace shortened, since the entire operation can be carried out by a single operator can.

In addition, because all chains are held back and over and over again during a long period of operation can be used, there is no consumption of chains or other shooting links when loading, so that the feed economy is improved.
