PURPOSE:To always obtain stable quenched characteristic by arranging energy beam control means controlling output and/or shifting velocity of the energy beam and restraining dispersion of the quenched characteristic. CONSTITUTION:This controller is composed of an electromagnetic wave detecting device 5 detecting the electromagnetic wave projected from surface of quenching part 3, temp. converting device 7 converting signal thereof into the temp. quenched characteristic assuming means, energy beam deciding means 8 and energy beam control means 9. The above quenched characteristic means treat the temp. distributing data 7a from the above device 7 to assume the quenched characteristic. And, the above deciding means 8 decide the output and/or the shifting velocity of the energy beam 1 based on the quenched characteristic assumed from the above assuming means. Further, the above control means 9 control the output and/or the shifting velocity of the energy beam based on output of the above deciding means 8.
