The continuous bright annealing furnace for steel pipe mainly consists of feeding frame, heating furnace, cooling box, discharging frame and ammonia decomposition furnace. As the idlers on the heating furnace and cooling box rotate continuously, the steel pipe moves forward continuously. In the working process, the mixture of 75% hydrogen and 25% nitrogen is put into the heating furnace body and cooling box, so that the workpiece in the furnace will not be oxidized and the workpiece will be bright. The equipment is mainly used for continuous bright annealing of steel pipe, stainless steel and other products. The continuous bright annealing furnace for steel pipe produced by Suzhou jinruier Electric Furnace Co., Ltd. has the advantages of simple operation, strong safety, meeting the national acceptance standard and strong manufacturability. Heat flow circulates back and forth in the furnace, with good temperature uniformity, no noise, no environmental pollution, small heat storage, less heat loss, high temperature control accuracy and strong temperature uniformity. It can effectively reduce the temperature of steel production, so as to produce bright and tough steel.
