Steel tube annealing is heating the steel to a certain temperature and holding for a period of time, and then cooling it slowly, which is called annealing.

Steel tube annealing is a heat treatment method that the steel tube is heated to the temperature of phase transformation or partial phase transformation, and then slowly cooled after heat preservation. The purpose of annealing is to eliminate the structure defects, improve the structure, homogenize the composition, refine the grain, improve the mechanical properties of the steel, reduce the residual stress, reduce the hardness, improve the plasticity and toughness, and improve the cutting performance. Therefore, annealing is not only to eliminate and improve the structural defects and internal stress left by the previous process, but also to prepare for the subsequent process. Therefore, annealing belongs to semi-finished product heat treatment, also known as pre heat treatment.

The continuous bright annealing furnace for steel tube is optimized and designed according to the actual use of the continuous annealing furnace at home and abroad. It is mainly used for continuous annealing of steel tube, bearing steel tube, stainless steel tube, copper alloy and other alloy super long tube and bar.
