How to calculate the heating time of a 1000kw ಮಧ್ಯಂತರ ಆವರ್ತನ ಕುಲುಮೆ for forging diameter 100 length 250 bars

A certain factory knows that the existing forging blanks are φ100×250mm, the heating time is 10 seconds/piece (including auxiliary time), and the initial forging temperature is 900°C. Calculate the configured power. Calculate the mass of φ100×250mm as 9.4Kg.

P=(0.168×1000×9.4)/(0.24×0.6×10)=1000KW

ಎಲ್ಲಿ:

0.168—The average specific heat of ferrous metals;

9.4—The quality of the workpiece (Kg);

1000—Temperature rise of workpiece heating;

0.24—Work heat equivalent;

0.6—average efficiency (in this example, 0.6, generally 0.5~0.65, and special-shaped inductors are lower, 0.4);

10—heating time (seconds)

Based on the above calculation, a 1KHz forging induction heating furnace with a rated power of 1000KW can be configured.
