(54) FURNACE FOR ELECTRIC SLAG; OVERFLOW ..

one

This invention relates to a special eurum specium.

A well-known furnace for electroslag remelting, containing guide pillars with electric motors Mn and molds placed on them, which have mechanisms for moving in a vertical plane.

However, the technological capabilities of such a furnace are often limited due to the lack of the required number of electrode holders and the degrees of freedom they possess. This is particularly true (refers to furnaces for smelting sheet ingots.

In the proposed furnace, on the side surfaces of the supporting structures of the electrode holders facing each other, current-carrying plates are installed, and the output shafts of the respective carriages of vertical movement of the electrode holders and crystallizers are located opposite each other and equipped with coupling half couplings, each of the electrode holders vertical movement in horizontal

The guides are equipped with a horizontal mixing drive, for example, a hydraulic cylinder.

FIG. 1 depicts the proposed oven, rear view; in fig. 2 - furnace with remelting into two crystallizers, front view; in fig. 3 - furnace with remelting in one mold, front view; in fig. 4 - furnace with remelting of one electrode in one mold, front view.

The furnace for electroslag remelting consists of columns 1, each of which is mounted with the possibility of vertical movement of the carriage of electrode holders 2 with drives 3 and the carriage of crystallizers 4 with drives 5, which are arranged so that the output shafts have a free exit with coupling half couplings 6, which are located opposite one another.

FIG. 1 shows that a furnace can operate as two independent furnaces or as one common one, if it is necessary to use the total capacity and the total capacity of the drives of both x furnaces for smelting double weight. The current carrying plates 7 dp of carrying the main electrodes 8 are arranged on the trolleys of the electrode holders 2, and on the side surfaces 9 facing one another. current-carrying plates 10: DNP carriers, additional electrode are installed. ; , ;;; -: FIG. 3 illustrates the joint operation of two electrode holders in a common crystallizer 11, as well as the possibility of horizontal movement of the two main electrode holders in horizontal routes SCH.X 12 with hydrocylinders 13 both when setting up the electrodes before melting and during melting. FIG. Figure 2 shows the possibility of separate operation of the electrode holder in separate crystallizers 14–15. Melting in this case proceeds according to different technological schemes: in one Case, by lowering consumable electrodes into a stationary mold, in the other, by the method of counter-movement of the mold and electrodes. FIG. 3 shows joint electrode holders using additional current leads 10, in which additional electrodes 16 are fixed; FIG. 4 - only the operation of an additional central electrode holder, in which it is possible to fix the electrode 17 with a total weight equal to the loading capacity of both drives. -. . .. . . The advantage of the electric holder, formed by the current leads located on the side surfaces of the layers of the electrode feeder structures, facing each other; To a friend: It is also possible that the current-carrying plates can be pushed and moved by horizontal mixing hydraulic cylinders, and this is very important if we consider that in such an electrode holder. you can attach the electrodes of almost any size. 1. About the furnace for electrically remelting, containing two or more guide columns with mounted on the electrode holders and molds with mechanisms of displacement, By the fact that, in order to provide a transition from smelting one assortment of ingots to another and using electrodes of different diameters, it is equipped with additional current-carrying plates located on the side surfaces of the electrode holders facing one another, and on the output shafts The movement shifts of the electrode holders and molds are mounted on the half coupling clutch. 2. on. 1, that is, so that the electrode holders are Equipped with the mechanisms of horizontal movement.
