PCT No. PCT/EP93/02795 Sec. 371 Date May 23, 1996 Sec. 102(e) Date May 23, 1996 PCT Filed Oct. 12, 1993 PCT Pub. No. WO94/13417 PCT Pub. Date Jun. 23, 1994A device for automatically operating slide gates for liquid metal containers, involving a fixed plate assembly rigid with a container base and a movable plate assembly hinged to the fixed plate assembly along a support element provided near a lateral edge thereof, and engageable with the fixed assembly when the slide gate structure is close. The device has means which first cause the pure axial translation of the support element so as to cause the movable plate assembly to slide tangentially with respect to the fixed plate assembly thus disaligning the pouring holes of the two plates, and then cause the axial rotation of the support to cause the movable plate assembly to rotate relative to the fixed plate assembly thus carrying out the opening of the slide gate structure. |
