Abstract: PURPOSE:To reduce the temperature drop at the tip of the material, in the induction heater provided with the pinch roller at the entry and the exit, by moving the heated material at high speed from the exit of the furnace to the exit pinch roller. CONSTITUTION:The feed pinch roller 4 is arranged at the entry of the heating furnace 1 provided with the induction heating coil 3, and the exit pinch roller 6 is arranged near the exit 5. The steel material A to be heated is fed into the furnace by the feed pinch roller 4, and is heated while being moved at low speed.

The high speed setter 8 switches the motor 11 to the high speed revolution, so that the material A is pushed out of the furnace at high speed. At the same time, the timer 10 for setting the high speed feeding time starts, and the high speed revolution is continued until the tip of material A arrives at the exit pinch roller 6 rotating at high speed. After that, the timer 10 makes a time-out, and the high speed setter 8 is switched to the low speed setter 9; hereby, the feed pinch roller 4 is altered to low speed revolution, and feeds the new material into the furnace.

Abstract: PURPOSE:To exactly control a head and to enable high-speed seek by detecting the velocity of the head for each prescribed moving distance and calculating the command value of an actuator each time the velocity is detected. CONSTITUTION:A digital signal processor (DSP) 8 is provided as a means to calculate the target velocity of a head 2 corresponding to a residual distance until the commanded target position of a recording medium 1, and a tracking error detector 2 detects the velocity of the head 2 each time the head 2 is moved to the recording medium 1 for the prescribed moving distance.
