Introduction of annealing method for Pressed ventilation elbow products

Heating Pressed ventilation elbow products to a certain temperature and heating for a period of time, and then slowly cooling, called annealing. Annealing of Pressed ventilation elbow products is a heat treatment method that heats the steel to a phase transformation or partial transformation after the insulation has cooled slowly. The purpose of annealing is to eliminate tissue defects, improve the organization to homogenize the composition and fine particles, improve the mechanical properties of Pressed ventilation elbow products, reduce residual stress; reduce hardness, improve plasticity and toughness, and improve cutting performance. Therefore, annealing is used to eliminate and improve the structural defects and internal stress left in the previous process, and to prepare for subsequent methods, annealing is a semi-finished heat treatment, also known as preheating.

Pressed ventilation elbow products

Tempering and annealing of U-shaped Pressed ventilation elbow products are reheated and annealed to determine elbow quality. If these two links are mastered, then our elbow production will increase productivity.

Cool it down by a certain method until seasoned. Its purpose is to eliminate internal stress generation and reduce hardness and brittleness to achieve the desired mechanical properties. Temperature tempering, medium tempering and low temperature steamboat. Most tempering is used with quenching and normal flame.
