How to calculate the power of induction heating furnace?

Power estimation formula: P=(C×G×T)/(0.24×t×∮)

P stands for equipment power (KW); C stands for metal specific heat coefficient, and steel specific heat coefficient is 0.17G—weight of heated workpiece (kg); T stands for heating temperature (℃); t stands for working cycle (seconds); ∮ stands for equipment The overall thermal efficiency is generally 0.5-0.7, and the special-shaped part is about 0.4.

例：鍛造工場には、Φ60×150mmの鍛造ブランク、12秒/個（補助時間を含む）の作業サイクル、1200°Cの初期鍛造温度があります。

計算は次のとおりです。P=（0.17×3.3×1200）/（0.24×12×0.65）= 359.61KW

Based on the above calculation, a GTR intermediate frequency induction furnace with a rated power of 400KW can be configured.
