How Does A Hydraulic Press Increase The Limit Of The Heating Rate?

1. The heating temperature of the tube billet should be appropriate and even to avoid various defects caused by improper heating, reduce the energy consumption of tools and rolling, so as to improve the productivity of the tube billet heating of the hydraulic press and the quality of the billet. The faster the heating speed of the hydraulic press, the shorter the time to reach the predetermined heating temperature, which can reduce the burning rate of the tube blank and improve the productivity of the heating furnace.
The so-called heating speed is the speed at which the temperature rises when the hydraulic press tube blank is heated. The heating temperature of the tube blank should be determined according to the temperature range that is most conducive to the plastic deformation of the metal.
2. The thermal conductivity of the metal of the hydraulic machine and the thermal stress during heating In the early stage of heating, the surface and center temperature of the tube blank are inconsistent, and the internal and external temperatures of the tube blank can be averaged only by the internal heat conduction of the metal.
