Abstract

Abstract:

The magnetic properties of the pure iron affect the core function of relays.The differences in magnetic properties of several pure iron materials are investigated primarily under various heat treatment processes and the impact on relay related performane is simulated.Finally, based on the actual usage scenarios of relays,the recommendations on the selection of pure iron materials and heat treatment processes of relay are put forward.

Key words: relay, pure iron, magnetic performance, heat treatment process

CLC Number:

TM58
