Abstract (en)
[origin: EP1589120A1] A linear furnace body of a heat treating furnace (1) houses in its inside a preheating chamber (3), a heat treating chamber (4) and a soaking chamber (5) with partitioning doors (1 and 2) arranged between them, respectively. Series of independently-driven hearth rollers (6, 7 and 8) are arranged in the chambers, respectively. Upon preheating and soaking of a work W, the series of hearth rollers (6 and 8) in the preheating chamber (3) and the soaking chamber (5) are rotated forward and backward to vibrate the work W. Upon heating of the work W, the series of hearth rollers (7) in the heat treating chamber (4) is stopped. <IMAGE>
