摘要

The movement toward carbon neutrality is expanding as a result of heightened environmental awareness. For soft-magnetic materials, whose usage is expected to increase as electrification progresses, the omission of the heat treatment step called magnetic annealing is regarded as one of the measures for reducing the amount of CO_2 produced by the manufacturing process. Kobe Steel's soft-magnetic pure iron, the ELCH2 series, has magnetic properties comparable to those of the magneticannealed material of low-carbon steel, even without magnetic annealing, and is being looked to as a nonheat-treated material of low-carbon steel. Using forging analysis and magnetic field analysis, a comparison has been made among the component characteristics when a solenoid iron core is changed from magnetic-annealed material of low-carbon steel to as-cold-forged material of ELCH2. This paper introduces the results indicating that the ELCH2, even if the magnetic annealing is omitted, achieves the same electromagnetic force at low current and also achieves higher electromagnetic force at high current than what is achieved by the magnetic-annealed material of low-carbon steel.
