METHOD OF INSTALLING A REFRACTORY LINING

摘要

A method of installing a refractory lining in a coreless or channel electric induction furnace. For installation of a refractory lining in a furnace wall , the method includes the steps of providing a dry refractory material between a liner form (32) placed within the furnace (50) and a furnace wall (72); placing at least one variable frequency/amplitude electric vibrator (10) in operational communication with an element selected from a structural member of the furnace (50), the liner form (32), and a vibrator rig (30) placed within the furnace (50); inducing flow of the dry refractory material by operating at least one variable frequency/amplitude vibrator (10) in a first operational mode having a high amplitude, low frequency vibration; and compacting the dr y refractory material by operating at least one variable frequency/amplitude vibrator (10) in a second operational mode having low amplitude, high frequency vibration after inducing flow of the dry refractory material.
