Title:
MONOLITHIC REFRACTORY FOR INDUCTION FURNACE
Document Type and Number:
Japanese Patent JP3928818
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refractory for lining an induction furnace capable of improving the operating rate of a plant, production cost and workability.
SOLUTION: The innermost side wall part or side wall part and bottom part of the furnace are produced by using a refractory material consisting of 5-30wt.% quartz material, 5-40wt.% silicon carbide material, 30-90wt.% high alumina material or alumina material containing ≥55wt.% Al2O3 and ≥90wt.% in total of three materials and, if necessary, properly adding a sintering assistant. The refractory is remarkably small in the occurrence of crack and free from the development the crack to harmful abnormal damage and is safely and stably used. The useful life is drastically prolonged and the stability of operation is effectively improved since abnormal damage is hardly caused.
