摘要：一種退火爐輻射冷卻系統緩冷段裝置及其控制方法,所述緩冷段裝置設置為48個區段,每個區段分別設置一個空氣流量控制閥(3)及溫度檢測儀,當溫度檢測儀檢測到爐內溫度時,信息通過反饋控制器(11)來調節空氣流量調節閥;每個區段均在帶鋼的上下方交叉布置輻射套管(2),通過輻射套管中的冷空氣輻射來對帶鋼進行降溫冷卻,連接各區段的流量調節閥(3)經空氣管道(4)連接至抽風機(5)后由排氣煙囪(6)排出.

 One kind of radiation annealing furnace slow cooling zone cooling system device and control method, the device is set to slow cooling section 4--8 zones, each zone are provided an air flow control valve (3) and temperature detector when the temperature detector detects the temperature in the furnace, information feedback controller (11) to regulate the air flow control valve; beneath each cross section are arranged in the strip of radiation sleeve (2), set by radiation (6) is discharged from the exhaust chimney in cold air to cool the radiation cooling of the strip, each segment connecting the flow control valve (3) through the air duct
