Ifomula yokulinganisa amandla wesithando somlilo sokungeniswa:

P=(C×G×T)/(0.24×t×∮)

Incazelo yefomula: P—amandla esisetshenziswa (KW); Ukushisa okukhethekile kwe-C-metal, lapho i-coefficient yokushisa ethize yensimbi ingu-0.17;

G-isisindo se-workpiece eshisayo (kg); T-izinga lokushisa lokushisa (℃); t – isigqi somsebenzi (imizuzwana);

∮—Ukusebenza kahle okushisayo kwesisetshenziswa ngokuvamile kungu-0.5-0.7, futhi cishe u-0.4 wezingxenye ezinomumo okhethekile.

Isibonelo: imboni yokubumba inesikhala sokubumba esingu-Φ60×150mm, umjikelezo wokusebenza yimizuzwana eyi-12/ucezu (kuhlanganise nesikhathi esiyisizayo), kanti izinga lokushisa lokuqala lokubumba lingu-1200 °C. Bese kubalwa amandla esithando somlilo se-GTR intermediate frequency electric sidingeka kanje: P=(0.17×3.3×1200)/(0.24×12×0.65)=359.61KW

Ngokwalesi sibalo esingenhla, okokusebenza kokushisisa kwe-GTR okunamandla alinganiselwe angu-400KW kungalungiswa.
