The steel tube micro oxygen annealing furnace 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, nitrogen is introduced into the heating furnace body and cooling box, so that the workpiece in the furnace will not be oxidized, so that the workpiece can achieve the effect of no oxygen scale or micro oxygen.

The equipment is mainly used for continuous bright annealing of steel pipe, stainless steel, copper pipe and other products.
