To align with manufacturing industry trends and advance deep processing of high-strength steel, this paper researched simulating partial heating roll forming (PHRF) for BR1500HS steel. By using electromagnetic induction heating and a finite element model, the effects of current, power frequency and heating distance on the sheet temperature were analyzed. The temperature rose with current and frequency but fell with heating distance. Higher frequencies caused uneven temperature due to the skin effect. Comparing PHRF to cold roll forming, PHRF significantly reduced springback, ensured uniform deformation, and improved stress distribution, leading to higher forming accuracy and quality.

摘要

The temperature rose with current and frequency but fell with heating distance. Higher frequencies caused uneven temperature due to the skin effect. Comparing PHRF to cold roll forming, PHRF significantly reduced springback, ensured uniform deformation, and improved stress distribution, leading to higher forming accuracy and quality.
