Conveyor Cooling Effects on the Wire Rod Residual Stresses during Production

Abstract:
In the recent years, industrial practice has proven that a more ductile wire rod can be produced by reducing the cooling rate of the produced wire during its travel on the conveyor, just after the laying head. This is important for low carbon wire rod (A¸5.5 mm) that is used for end-user applications which require relatively small -sometimes even below A¸1 mm- final wire diameters; it is succeeded by covering the moving wire with specific covers insulated by a low density ceramic material. In this way, the material exhibits lower hardness, and larger percent-elongation values at breakage. Residual stresses coming from thermal stresses during cooling at the conveyor are considered to be a reason and a short computational study was carried out in order to prove this assumption. A special computer program that takes under consideration the thermal, stress, and strain phenomena across a section of the wire rod based upon existing theory was developed. It seems that residual stresses can be attributed upon cooling schemes, verifying industrial practice. Similar phenomena have been analyzed for wire rods quenched up to certain depths, which will be presented as well.
