PAN FOR INDUCTION HEATING COOKING

摘要

PURPOSE: To improve the durability and lower the cost regarding a cooking pan produced by joining a ferrous magnetic material to the bottom of a main body made of aluminum for induction heating cooking. CONSTITUTION: Regarding a pan for induction heating cooking which is produced by joining and uniting a plate-like heat radiating member 2 made of a ferrous magnetic material with the outer bottom of a main body 1 made of aluminum; a circular groove 3 is formed in a joining face 2a of either one having higher mechanical strength between the main body 1 and a heat radiating member 2. While the main body 1 and the heat radiating member 2 being pressured in the joining direction, the main body 1 and the hear radiating member 2 are joined by friction- and press-joining in which the main body 1 and the heat radiating member 2 are rotated relatively on the groove 3 as a rotary axis, It is preferably that the groove 3 is a taper groove having a cross-section shape with narrower groove width in the bottom than the open part.
