PURPOSE:To continuously execute heat-treatment, such as quenching, annealing, on a product to be treated in the continuous heat-treating furnace by arranging heating part together with cooling room toward carrying direction of the product to be treated in the same room of continuous heat-treating furnace. CONSTITUTION:In the above continuous heat-treating furnace 1, the product 10 to be treated is laid on a mesh-belt 2, so that the part to be treated in the product 10 is positioned in the heating part 13. And, while circulating the belt 2 toward the direction of the arrow mark A, the product 10 is moved from the left side to the right side of the furnace 1 shown in the figure. Therefore, a part of product 10, passing through in the heating part 13 heated by a heater 17 and set at the prescribed temp., is heated at the above prescribed temp. On the other hand, while temp. of the other part of the above product 10 passing through the cooling part 14 is not practically raised the treating product is carried. In succession, after the product 10 partially heated at the prescribed temp. is carried out from the heating part 13 and the cooling part 14 of heating room 11, it is sent to a slow cooling room 12, to cool the above heated part at the prescribed cooling speed, and the treatment, such as gas quenching, tempering, annealing, normalizing, brazing, is executed.
