PCT No. PCT/IT94/00092 Sec. 371 Date Mar. 17, 1995 Sec. 102(e) Date Mar. 17, 1995 PCT Filed Jun. 22, 1994 PCT Pub. No. WO95/04250 PCT Pub. Date Feb. 9, 1995A pushing machine is described, which is capable of running to opposite directions, upon remote control, along a length of rail provided in front of the mouth or slag hole of an electric furnace (10) for the smelting of iron products. It shows, at the end of an arm (5, 5a) telescopically extensible and preferably pivoting to be able to swing also in the vertical plane, a head or front shield (6) mounted on a frame (1) which can be anchored to the ground and is slidable on rails by means of wheels (2, 2' . . . ), at least two of which are driving wheels. Said shield (6), having a size slightly smaller than the slag hole, has the function of keeping the scrap at the inside of the furnace during the charging operation and keeping the threshold free of the slag without any operator's intervention. |
