PURPOSE: A batch type annealing heat treatment facility free from the danger of an explosion is provided to have an ambient gas flowing into a furnace by an alternating combustion of combustors whereby a separate flow fan is required. CONSTITUTION: A batch type annealing heat treatment facility(10) comprises a furnace(110), a supporting member, a cover(120), multiple combustors and a cooling member(300). The cooling member includes a circulation duct(310), a heat exchanger(320) and a circulation fan(330). The circulation duct has both ends connected to the furnace. The heat exchanger is installed on the circulation duct and cools the ambient gas flowing into the circulation duct. The circulation fan is installed on the circulation duct. |
