METHOD OF LINING METALLURGICAL ASSEMBLY

摘要

A method of lining a metallurgical assembly, in particular a coreless induction furnace comprises lining a furnace bottom, mounting a gauge for forming an inner wall of the lining on the lined bottom, and layer-by-layer filling a space provided between the gauge and an induction heater of the furnace with a lining mass while compacting each layer. Thickness of each layer is 4 to 10 values of said space. The layers are compacted by applying periodically repeated blows against the inner surface of the gauge and in the direction perpendicular to a plane tangential to this surface of the gauge. The blows are applied with an interval being not less than the damping time of free oscillations o-f the furnace. The inventive method makes it possible to ensure uniform compaction of the lining mass in the direction of crucible height and differentiated compaction in the direction of thickness thereof and thereby to increase the lining durability.
