EQUIPMENT FOR WIRE ANNEALING
Annealing - a type of heat treatment of metals and alloys, comprising heating to a certain temperature, aging and then, usually, slow cooling. The purpose of annealing is to eliminate arising in the metal structure during molding, pressure treatment, welding deviations from the equilibrium state, i.e. Returns the crystal structure and homogenization. Annealing is carried out to reduce hardness and enhance treatment ability, improve the structure and achieve uniformity with the elimination of internal stress.
