Abstract
The proposed method relates to metallurgy and foundry engineering. The process of lining a metallurgical assembly, in particular an induction furnace (1) is carried out in the following sequence. First, a bottom (2) is lined using a conventional method, following which a gauge (3) for forming an inner wall of the furnace lining is mounted thereon, and a space (5) provided within the gauge (3) and an induction heater (4) of the furnace (1) is filled with a lining mass (6). The lining mass is filled in layers each having a thickness of 4 to 10 values of said space (5). The layers are compacted by applying periodically repeated blows against the inner surface of the gauge (3). These blows are applied in the direction perpendicular to a plane tangential to said surface of the gauge (3), the interval between the blows being not less than the damping time of free oscillations of the furnace. The above described method may be used when carrying out rammed lining within coreless induction furnaces.
