精密鋼管溫度主要受高頻渦流熱功率的影響，根據(jù)公式可知，高頻渦流熱功率主要受電流頻率的影響，渦流熱功率與電流激勵(lì)頻率的平方成正比;而電流激勵(lì)頻率又受激勵(lì)電壓、電流和電容、電感的影響。激勵(lì)頻率公式為：f=1/[2π式中：f-激勵(lì)頻率;C-激勵(lì)回路中的電容，電容=電量/電壓;L-激勵(lì)回路中的電感，電感=磁通量/電流上式可知，激勵(lì)頻率與激勵(lì)回路中的電容、電感平方根成反比、或者與電壓、電流的平方根成正比，只要改變回路中的電容、電感或電壓、電流即可改變激勵(lì)頻率的大小，從而達(dá)到控制精密鋼管溫度的目的。對于低碳鋼，精密鋼管溫度控制在1250~1460℃，可滿足管壁厚3~5mm焊透要求。另外，精密鋼管溫度亦可通過調(diào)節(jié)精密鋼管速度來實(shí)現(xiàn)。
