Abstract

PURPOSE:To shorten responsing time of actual temp. to the aimed temp. of the material to be heated by arranging gas circulating passage to outlet part of a furnace to forcedly circulate the atmospheric gas and cooling the gas to lower the temp. in the furnace. CONSTITUTION:Gas duct 14 for the gas circulating passage communicating with the inner part of the furnace body 2A is arranged at roof surface of the furnace body 2A of annealing furnace 2, etc. On the way of the gas duct 14, a gas blower 15 for gas circulating means and a gas cooler 16 for gas cooling means are arranged to forcedly circulate the atmospheric gas in the inner part of the furnace 2. An introducing pipe 17 is connected with the gas duct 14 at the downstream of the blower 15 and at the time of being short of cooling capacity of the cooler 16, new atmospheric gas is supplementarily supplied in the furnace 2. The aimed furnace temp. corresponding to the aimed strip temp. is set and by working the gas blower 15, the forced cooling of the atmospheric gas is executed. By this method, the strip temp. can be set to the aimed temp. for a short time.
