INDUCTION HEATING COOKING DEVICE AND ALLOY FOR ITS CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide an induction heating cooking device and an alloy for manufacturing its container. SOLUTION: This induction heating cooking device has a heating part made of a ferromagnetic alloy having a Curie temperature of 150-370 deg.C, and a magnetostriction coefficient ofλs<=5×10-6 at absolute value. This alloy used for manufacturing the cooking device has a chemical composition, comprising 50-85 wt.% of Ni, 50 wt.% or less of Cu, 12 wt.% of X=Cr+Mo+Mn+Si+Al+ W+Nb+V+Ti and the remainder including iron and unavoidable impurities, and is an FeNiCuX type alloy that satisfies relation inequalities (35/25)×(75-Ni)<=Cu<=(50/35)×(85-Ni) and (7/20)×(Ni-65)<=X<=(12/35)×(Ni-50), and the like.
