Hydrodynamic theory predicts higher pressure at higher drawing speed, but the opposite is true. The temperature in the area of wire and die interface influences lubricant properties, including viscosity. In this paper, the wiredrawing process was studied by means of coupled thermo-mechanical simulations using the Finite Element Method. The temperatures in the die, the wire, and the interface were evaluated, for different parameters such as wire steel grade, drawing speed, and die cooling conditions. This paper discusses their influence on lubrication.
