ARC FURNACE ARRANGEMENT I.E. THREE-PHASE ARC FURNACE ARRANGEMENT, HAS CRADLE FRAME FITTED ON RAILS WITH WHEELS BY CONTROL OF HYDRAULIC CYLINDER UNITS AND MAIN SUPPORTS SO THAT CRADLE FRAME EXTENDS OUT FROM REGION WITHIN LIFTING FRAME.

摘要

The arrangement has a metallurgical container (8) arranged in a cradle frame (7), which is positioned on an upper side of a lifting frame (1). Two cross beams (9) i.e. concrete walls, are arranged below the cradle frame. Rails (10) are arranged on the cross beams. Wheels (11) are arranged at the cradle frame. The cradle frame is fitted on the rails with the wheels by corresponding control of hydraulic cylinder units (3) and main supports (4) so that the cradle frame extends out from a region within the lifting frame on the rails in an extending direction (C) after fitting on the rails.
