ABSTRACT:
A continuous heat treating furnace is equipped with an automatic flow control system and contains a high-temperture treating zone internally provided with a plurality of burners, a pre-heating zone connectively disposed at one end of the high-temperature treating zone and a cooling zone connectively disposed at its other end, the pre-heating and cooling zones being partitioned into a plurality of compartments each provided on its ceiling portion with a convection fan. The automatic flow control system includes a first duct for communicating a terminal compartment of the pre-heating zone and a first compartment of the cooling zone, a second duct for communicating a terminal compartment of the cooling zone and a first compartment of the pre-heating zone, a first flow regulating damper disposed in the course of the first duct to regulate a flow rate of atmosphere gas flowing in the first duct, and a second flow regulating damper disposed in the course of the second duct to regulate the flow rate of the atmosphere gas flowing in the second duct. By such an arrangement, the flow rate of the atmosphere gas introduced into the pre-heating zone and that introduced into the cooling zone are automatically regulated to coincide with each other.
