Influence Of Different Ecoquench Temperature On High Carbon Steel Wire Mechanical Properties

Abstract

Patenting heat treatment wires in the production of bead wire, spring wire, prestressed concrete wire and wire rope provide suitable microstructural properties for subsequent diameter reduction steps. The process of patenting in the fluidized bed, which is a faster and more environmentally friendly process than the conventional lead bath, is carried out in two stages: After heating to the austenitizing temperature, a thin perlite structure is obtained after cooling at the appropriate speeds in the fluid sand bed. Both high tensile strength and ductility can be achieved by suitable patenting conditions. The effect of fluid bed temperatures and cooling rate on the success of the process is of critical importance. In this study, mechanical properties (tensile, elongation, elongation ratio, torsion) and microstructure effects of different fluidized bed temperatures for wt.%0,83 carbon wires at 3.5 mm diameter were investigated.
