Method for preparing thermal deposition copper foil through titanium ring rolling

Abstract

The invention discloses a method for preparing a thermal deposition copper foil through titanium ring rolling. The method comprises the steps that a Gleeble-1500D thermal simulation test machine is used for carrying out thermal stretching on a deposition copper foil through industrial pure titanium TA1 under the conditions that the temperatures are 800 DEG C, 850 DEG C, 950 DEG C, 1000 DEG C and 1050 DEG C and the strain rates are 0.01, 0.1 and 1s-1, and when the industrial pure titanium is broken at 800-850 DEG C, a fracture is a typical ductile fracture; with rising of the temperature, the plasticity of the pure titanium is improved at 900-1050 DEG C, a fracture is a quasi-cleavage fracture, and deformation resistance behaviors of the industrial pure titanium TA1 shows typical restoration and recrystallization softening features; and below the phase change temperature, dynamic recrystallization occurs during high-temperature stretching of the industrial pure titanium. According to the method for preparing the thermal deposition copper foil through titanium ring rolling, the comprehensive performance of rings produced in a simulation mode is the best under the conditions that therotating speed v of a driving roller is low and is equal to 1.75 rad / s, a 0.3-0.5-0.3 mm / s segmental feeding mode is adopted by a core roller, the initial rolling temperature is 850 DEG C and lower than the phase change temperature, and the friction coefficients of the driving roller and a conical roller are as high as 0.7.
